General

Awareness of the necessity ofpower quality is increasing, andpower factor correction (PFC) willbe implemented on a growingscale in future. Enhancing powerquality – improvement of powerfactor – saves costs and is a fastreturn on investment.In power distribution, in low- andmedium-voltage networks, PFCfocuses on the power flow (cos ϕ)and the optimization of voltagestability by generating reactivepower – to improve voltagequality and reliability at distribu-tion level.

How reactive power isgenerated

Every electric load that works withmagnetic fields (motors, chokes,transformers, inductive heating,arc-welding generators) producesa varying degree of electrical lag,what is called inductance. This lagof inductive loads maintains thecurrent sense (eg positive) for atime even though the negative-going voltage tries to reverse it.This phase shift between currentand voltage is maintained, currentand voltage having opposite signs.During this time, negative poweror energy is produced and fedback into the network. When cur-rent and voltage have the samesign again, the same amount ofenergy is again needed to buildup the magnetic fields in inductive

loads. This magnetic reversalenergy is called reactive power. In alternating voltage networks(50/60 Hz) such a process repeats50 or 60 times a second. So anobvious solution is to briefly storethe magnetic reversal energy incapacitors and relieve the network(supply line) of this reactiveenergy.For this reason, automatic reactivepower compensation systems(detuned/conventional) are installedfor larger loads like factory plants.Such systems consist of a group ofcapacitor units that can be cut inand cut out and which are drivenand switched by a power factorcontroller as determined by acurrent transformer.

Power factorLow power factor (cos ϕ)Low cos ϕ results ina higher energy consumption

and costs,a less power distributed via the

network,a power loss in the network,a higher transformer losses,a increased voltage drop in

power distribution networks.

Power factor improvement

Power factor improvement can beachieved bya compensation of reactive power

with capacitors,a active compensation – using

semiconductors,a overexcited synchronous

machine (motor/generator).

Types of PFC (detuned or conventional)

a individual or fixed compensa-tion (each reactive powerproducer is individually com-pensated),

a group compensation (reactivepower producers connected asa group and compensated as awhole),

a central or automatic compensa-tion (by a PFC system at acentral point),

a mixed compensation.

Fundamentals of Power Factor Correction

What is power factorcorrection?The rational use of electricalenergy calls for economical gener-ation, transmission and distribu-tion with little loss. That meansrestricting all factors in electricalnetworks that cause losses. One ofthese factors is lagging reactivepower. Consumers in industrialand public electrical networks areprimarily of an ohmic-inductivenature.The purpose of systems for powerfactor correction in networks is tocompensate the generated lag-ging reactive power by leadingreactive power at defined nodes.In this way impermissibly highvoltage drops and additionalohmic losses are also avoided. The necessary leading power isproduced by capacitors parallel to

the supply network, as close aspossible to the inductive con-sumer. Static capacitive compensa-tion devices reduce the laggingreactive power component trans-mitted over the network. If net-work conditions alter, the requiredleading reactive power can bematched in steps by adding andtaking out single power capacitors(regulated PFC) to compensate thelagging reactive power.

Key componentsPFC controllerModern PFC controllers are micro-processorized. The microprocessoranalyzes the signal from a currenttransformer and produces switch-ing commands to control the con-tactors that add or remove capaci-tor stages. Intelligent control bymicroprocessorized PFC controllersensures an even utilization ofcapacitor steps, minimized numberof switching operations and opti-mized life cycle.

FuseAn HRC fuse or MCCB acts as asafety device for shortcircuitprotection.

Capacitor contactorContactors are electromechanicalswitching elements used to switchcapacitors or reactors and capaci-tors in standard or detuned PFCsystems. The switching operationcan be performed by mechanicalcontacts or an electronic switch(semiconductor). The latter solu-tion is preferable if fast switchingis required for a sensitive load forexample.

Reactor (compensation and filtering)Power distribution networks areincreasingly subjected to harmonicpollution from modern powerelectronic devices, socalled non-linear loads, eg drives, uninter-ruptible power supplies, electronicballasts. Harmonics are dangerousfor capacitors connected in thePFC circuit, especially if the capaci-tors operate at resonant frequency.The series connection of reactorand capacitor to detune the seriesresonant frequency (the capaci-tor's resonant frequency) helps to prevent capacitor damage.Critical frequencies are the 5th and7th harmonics (250 and 350 Hz).Detuned capacitor banks alsodecrease the harmonic distortionlevel and clean the network.

CapacitorPower factor correction capacitorsproduce the necessary leadingreactive power to compensate the lagging reactive power. PFCcapacitors should be capable ofwithstanding high inrush currentscaused by switching operations (> 100 * IN). If capacitors areconnected in parallel, ie as banks,the inrush current will increase (≥ 150 * IN) because the chargingcurrent comes from the grid aswell as from capacitors parallel tothe switched one.

Benefits of power factorcorrectiona Amortization in eight to

24 months through lowerpower costs

Power factor correction reducesthe reactive power in a system.Power consumption and thuspower costs drop in proportion.

a Effective installation useAn improved power factor meansthat an electrical installation worksmore economically (higher effec-tive power for the same apparentpower).

a Improved voltage qualitya Fewer voltage dropsa Optimum cable dimensioningCable cross-section can bereduced with improvement ofpower factor (less current). Inexisting installations for instance,extra or higher power can betransmitted.

a Smaller transmission lossesThe transmission and switchingdevices carry less current, ie onlythe effective power, meaning thatthe ohmic losses in the leads arereduced.

Voltage fluctuations (transientovervoltage, up/down voltagefluctuation, flicker)These are mostly caused by thepower consumption of large loadslike welding machines and arcfurnaces, or by heavy power fluc-tuations. These random voltagefluctuations are often also referredto as flicker, because they arenoticeable as visible alterations inlighting installations. They are not

only disturbing to the human eye,they can also disrupt sensitiveproduction processes. On weaknetworks, flicker can affect largegeographic areas. Dynamic volt-age compensation is a possibleremedy.Harmonic distortion is the result ofnonlinear loads and can also leadto malfunction of the equipmentconnected. Apparatus can bedamaged by resonant effects in a network. Active and passivefilters offer protection against thisphenomenon.

Commutation notches are usuallyproduced by power electronicdevices and can be reduced bycircuitry measures.

Design of capacitorsa MKK/MKP technologyThe broad field of application forcapacitors combined with physicaland economic considerationscreates the need for differentdielectric technologies.When it comes to low-voltagepower factor correction, MKK/MKP(metalized plastic film/polypropy-lene) has demonstrated that it iscurrently the most suitable andmost economic technology. Thethickness of the dielectric differs asa function of voltage rating. Themetalization (with zinc and alu-minum as its major constituents)and edge enhancement withextra junctions or cross-profilemetalization play a significant rolein achieving high current handlingand stable capacitance at highoperating temperatures. Heavyedged and special film cutting

technique (optimized combinationof wavy and smooth cuts) pro-duces a maximum effective surfacefor the metal spraying or contact-ing process (winding design). Thisresults in exceptional surge currentcapability. The pinching effect onthe film edge of the winding – thecause of contact edge problems –is demonstrably eliminated in thisway.

a Self-healingAn electric breakdown is possibleas the result of thermal or electricoverload or at the end of servicelife. This results in a small arc thatevaporates the metalization in theregion of the breakdown in amatter of microseconds. The gaspressure caused at this spot by thehigh temperature blows the in themeantime vaporous metalizationout of the breakdown region.Which means that a non-conduct-ing isolation region free of metal-ization is formed here.

During and after the breakdownthe capacitor is fully functional. Thereduction in capacitance caused byself-healing is less than 100 pF, ie ofan order that can only be verifiedby a precision measuring instru-ment.

a Vacuum impregnationThe active winding elements areheated and then dried for adefined period. Impregnation (egby gas) is performed in a highvacuum. In this way air and mois-ture are extracted from the innercapacitor, and oxidation of the elec-trodes as well as partial dischargesare avoided. Afterwards capacitorsare hermetically sealed in cases (egaluminum). The elaborate processensures excellent capacitancestability and long service life.

a Overpressure disconnectorElectrical components do not haveunlimited service life, that appliesto self-healing capacitors too. Aspolypropylene type capacitorsseldom produce a pronouncedshortcircuit, fuses do not offerreliable protection.All capacitors featured in this cata-log are consequently fitted with adisconnector that responds tooverpressure. If numerous electricbreakdowns occur at the end of

service life or as the result of ther-mal or electric overload, the for-mation of gas produces a fast risein pressure inside the capacitorcase. With cylindrical cases thiscauses a change in lengthbecause of curvature of the lid orstretching of the expansion bead.Expansion beyond a certaindegree will separate the internalwires and disconnect from theline. Then the capacitor receivesno more energy and the develop-ment of gas stops.

To ensure full functionality of anoverpressure disconnector, itselastic elements must not behindered, ie– connecting lines must be flexible

leads (cables),– there must be sufficient space

for expansion above the connec-tions (stated for the differentmodels),

– folding beads must not beretained by clamps

Definitionsa Temperature class of capacitors

to standard IEC 831-1Capacitors are divided into tem-perature classes. Each class isrepresented by a number followedby a letter, eg –40/D. The numberis the lowest ambient temperatureat which a capacitor may operate.The upper limit temperature isindicated by the letter (see tableabove).

One should always remember thatthe useful life of a capacitordepends very much on tempera-ture. Proper cooling of a capacitormust ensure that the maximumcase temperature is not exceeded,otherwise service life is degraded.When configuring a circuit, oneshould make sure that capacitorsare not subjected to heat fromadjacent components (reactors,bus bars, etc). Forced cooling ispreferable for compact designs.And it is highly inadvisable toarrange capacitors directly abovereactors.

a Enclosure of capacitors (IPxx)For different models there aredifferent types of enclosure. Thetype of enclosure is indicated by adesignation consisting of the twoletters IP followed by two digits.

a Maximum admissibleovercurrent

The nominal current (IN) is thecurrent resulting for nominalvoltage (UN) and frequency (Hz),excluding transients. The maxi-mum admissible overcurrent (Imax)of 1.5 * IN to IEC standard 831 ismaintained by all capacitors in this catalog. The figures for over-current allow for the combinedeffects of harmonics, overvoltageand capacitance tolerance.

a Maximum admissibleovervoltage

Capacitors from EPCOS are suit-able for operation on overvoltagesquoted by IEC 831 (see table).

a Useful lifeThe statistical useful life of powercapacitors is governed by thefollowing factors:– duration of overload,– ambient temperature and the

resulting case temperature,– maximum rms current and the

resulting case temperature,– maximum voltage.The calculated service life of thevarious series is stated for nominaloperating conditions. If compo-nents are stressed less than theabove IEC 831 factors, longeruseful life can be expected, and acorrespondingly shorter one ifnominal parameters are exceeded.

Application notesa Fuse protectionPower capacitors can be protectedagainst shortcircuits by fuses ormagnetic shortcircuit releases.Preferable are slow-blow, low-voltage high-breaking-capacityfuses. The fuse rating should be1.6 to 1.8 times the nominalcurrent of the capacitor. Magneticshortcircuit releases should be set to between 9 and 12 timesnominal current to prevent themresponding to high inrushcurrents.

a SwitchingWhen a capacitance is switched toan AC system, the result is a reso-nant circuit damped to a greateror lesser degree. In addition to thenominal current, the capacitoraccepts a transient current that isa multiple of (as many as 200times) its nominal current. Fastswitching, low-bounce contactorsshould be used, observing theswitching capacity for capacitivecurrents stated by the producer.Recommended are special capaci-tor contactors with leading con-tacts that feature prechargingresistors to damp inrush currents(see chapter 3).

a DischargingCapacitors must be discharged tomaximally 10% of nominal voltagebefore cutting them in again. This prevents an electric impulsedischarge in the application, influ-ences the capacitor's useful life inPFC systems, and protects againstelectric shock. The capacitor mustbe discharged to 75 V or lesswithin 3 min. There must not beany switch, fuse or any otherdisconnecting device in the circuitbetween the power capacitor andthe discharging device. EPCOSsupplies capacitor dischargeresistors to all series, or alternative-ly discharge reactors (chapter 6)be supplied.

a Use in networks withharmonics

Harmonics are produced in theoperation of electric loads with anonlinear voltage/current charac-teristic (eg rectifiers and invertersfor drives, welding apparatus anduninterruptible power supplies).Harmonics are sinusoidal voltagesand currents with higher frequen-cies of a multiple of the 50 or60 Hz line frequency. In low-voltage three-phase systems the5th and 7th harmonics are espe-cially troublesome. Detuned capaci-tors should be used for power

factor correction in systems sub-ject to harmonics. These representa series resonant circuit of powercapacitor and reactor. The circuit istuned so that the series resonantfrequency is below the harmonicsappearing in the system. This pro-duces an inductive response to allfrequencies above the series reso-nant frequency, avoiding reso-nances with system inductances.Depending on the selected seriesresonant frequency, part of theharmonic current is taken up bythe detuned power capacitors.The remainder of the harmoniccurrent flows into the superordi-nate system. The use of detunedpower capacitors thus contributesto reducing voltage distortionthrough harmonics and lessensthe disturbing effect on properoperation of other electric loads.

a InstallationSpecifications like VDE 0100, VDE0101, VDE 0560 part 4 and 46,EN 60831 and IEC 831 apply tothe installation and operation ofpower capacitors. They should besited in cool and well ventilatedlocations away from other heat-radiating elements. Natural heatdissipation is generally sufficientfor cooling purposes if enough airis able to flow to and away fromthem and the capacitors arespaced at least 50 mm apart.Otherwise, in a less well ventilatedenvironment, forced cooling (fans)will be necessary, scaled so thatthe maximum admissible ambienttemperature is not exceeded.

– undervoltage detection– overvoltage detection– low measurement current– exceeded measurement current– insufficient capacitor output– harmonics limits– over temperature

a PrincipleThe new, microprocessorized (fast16 Bit processor) PROPHI is usedfor power factor correction in thelow-voltage sector. It features intel-ligent control and an LCD displaywith indication of harmonics andnumerous other parameters.

The single-phase, electronicmeasuring system detects thereactive and active component ofthe network through the currentand voltage path. From this itcalculates the phase shift betweenthe fundamentals of current andvoltage and compares this to theset target power factor.

If there are deviations, capacitorstages are cut in and out by theoutputs. This contactor control isoptimized so that the desired cos ϕis achieved with minimum switch-ing operations.

ApplicationShort circuit protectionAdvantage:a Easy replacement

Equipment and systems need tobe safeguarded so that they pre-sent no danger to persons or theenvironment in the event of adefect or failure. This protection isalso important so that all thefunctions of equipment or sys-tems become available again asfast as possible after a defect orfailure. Possible solutions arefusible cutouts (exchangeable) orautomatic circuit-breakers.

Types of protectionFuse elements must meet therequirements of the major interna-tional standards and recommenda-tions, eg IEC 947-1, 947-2, 947-3and 947-4, EN 60947-1 and60947-2, VDE 0660T107,CSA C22.2, UL 1077 and JIS.Equally important are thosestandards concerning climaticrequirements.

Personal protectionIntegrated personal protection (egIP54) is defined by EN 60529 andDIN 40050 and also applies tofuse elements.This also covers protection againstforeign bodies (graded by the firstdigit) and the ingress of water andmoisture (second digit).

HRC-Fusesa HRC-fuses do not protect a ca-

pacitor against overload - theyare for short-circuit protectiononly

a The HRC fuse rating should be1.6 to 1.8 times nominal capaci-tor current

a Do not use HRC-fuses forswitching (risk of arcing!)

a PrincipleOnly devices specially designedfor the purpose should be used toswitch PFC capacitors. Capacitorcontactors should be designed toavoid contact bounce and theresulting high transients. Theinrush currents must be limited toless than the nominal current ofthe contactor and the capacitor.

In modern PFC capacitors, highpower density and reduction oflosses have led to low inductanceand small series resistances.Circuits of capacitors, especiallythe parallel connection of capa-citors that are already activated,lead to extremely high inrushcurrents (> 200 x IN). This has anegative effect on the useful life of both contactors and capacitors,besides degrading the powerquality in a network.

In capacitor contactors withprecharging resistors, theseresistors are switched by leadingauxiliary contacts. The auxiliarycontacts close before the maincontacts and precharge the capac-itor. This significantly reduces highinrush currents on the capacitor.

capacitor contactora Soft switching of capacitor and thus

better useful lifea Enhanced mean lifetime of PFC systema Reduced ohmic lossesa Leading contacts with wiper function

Capacitor contactor for switch-ing detuned and conventionalthree-phase capacitorsa PrincipleWhen a capacitance is switched to an AC system, the result is aresonant circuit damped to agreater or lesser degree. In addi-tion to the nominal current, thecapacitor accepts a transient cur-rent that is a multiple of (as manyas 200 times) its nominal current.Fast switching, low-bounce con-tactors should be used.Because of the leading contacts,the inrush current spikes (reversecharging operations) are limited ordamped by resistance wires. Thesecurrent spikes would lead to weld-ing of the contactor's main con-tacts and they are also harmful forthe capacitors. Reduction of theinrush currents also avoids tran-sients and voltage sags.

Leading contacts with a wiperfunction are used in these capaci-tor contactors, ie each leadingcontact is linked to the contactoryoke by a permanent magnet. Theleading contacts close before themain contacts and open when themain contacts are with certaintyclosed. This feature of the capaci-tor contactors guarantees effec-tive, stable operation throughoutuseful life. The single controlledleading contacts also enhanceresistance to soiling during opera-tion.

The capacitor contactors aresuitable for direct switching of low-inductance and low-loss ca-pacitor banks (IEC 831, VDE 0560)with or without detuning reactors.They feature leading auxiliaryswitches and damping resistors toreduce peak inrush to < 70 * Iin(inrush current).The capacitor contactors are weldresistant up to a possible peakinrush current of 200 x Iin. Thebackup fuses gL (gG) should bescaled for 1.6 to 1.8 * Iin.All capacitor contactors come withan auxiliary contact (normally open).

9.2. Antiresonance three-phase filter reactorFeaturesa High resistance to harmonicsa Very low lossesa High linearity to avoid choke tilta Low noisea Simple mountinga Long useful lifea Temperature protection (NC contact)

a PrincipleElectrical energy is a significantproduction factor for industry,and its efficient use should be aprimary objective. Reducing thereactive current component byPFC correction helps to saveenergy.The increasing use of modernpower electronic apparatus(drives, uninterruptible powersupplies, etc) that produce non-linear current influences andloads the network with harmon-ics (line pollution).

The power factor correction orcapacitance of the power capa-citor forms a resonant circuit inconjunction with the feedingtransformer. Experience showsthat the self-resonant frequency ofthis circuit lies typically between250 and 500 Hz, ie in the regionof the 5th and 7th harmonics.Resonance can lead to the follow-ing undesirable effects:– overloading of capacitors,– overloading of transformers and

transmission equipment,– interference with metering and

control systems, computers andelectrical gear,

– resonance elevation, ie amplifi-cation of harmonics,

– voltage distortion.

These resonance phenomena canbe avoided by connecting capaci-tors in series with filter reactors.Detuned systems are scaled sothat the self-resonant frequency isbelow the lowest line harmonic.The detuned PFC system is purelyinductive seen by harmonics abovethis frequency. For the 50 Hz linefrequency, the detuned systemacts purely capacitively, thuscorrecting the reactive power.

GeneralPhaseCap capacitors in cylindricalaluminum cases were designedfor power factor correction inlow-voltage plant. Loads likemotors and transformers consumeactive power as well as reactivepower. Generators, supply cablesand other electrical distributionequipment, in turn, should berelieved of reactive power. TheMKK (metalized plastic compact)AC series (> 2.5 to 30 kvar) isintended to increase packing den-sity per bank and cut componentcosts. Improved thermal responseand simplified installation areadvantages of the cylindricalaluminum case.

Technical Data

The compact PhaseCap capacitor isa self-healing, metalized polypropy-lene film capacitor. The current-carrying metal layer (electrode) isvapor-deposited onto one side ofthe film.

Compact design – low height,weight and volumeThree electrically separated, partialcapacitors are wound concentrical-ly in a single operation onto aninsulated metal core tube, whichguarantees excellent winding pre-cision. The electrodes are connect-ed by metal spraying the face endof the winding element. The partialcapacitors are star, delta or seriesconnected.

The compact MKK winding ele-ments are housed in a cylindricalaluminum case and hermeticallysealed by a press-rolled metal lid.

Triple safety systema Dry technology: instead of a

liquid impregnating agent, thecapacitor is filled with gas. Sothere is no risk of fire caused byspurting or leaking oil. Drydesign is a must for ecologicallysensitive applications and insur-ance follow-up.

a Self-healing: the capacitor repairsitself after overload.

a Overpressure disconnector: thisprevents the capacitor frombursting at the end of its usefullife or through electrical orthermal overload.

Innovative and reliable SIGUT®

connection technologySIGUT terminals ensure reliable andstraightforward connection, even ina parallel capacitor circuit, withbenefits likea simplified parallel connection of

input ends in series,a protection against electric shock

hazard (IP20/IP54 to VDE 0106part 100),

a additional connection ofdischarge resistors for extrareliability and safety,

a clamping device to preventloosening of screws,

Extended useful life of 115,000 operating hoursAfter a long drying phase in a highvacuum to eliminate moisture fromthe active element, the capacitor isimpregnated. The case is filled withinert gas and sealed. Then routinetest are performed for gas leakage.

This production process helps toavoid oxidation and partial dis-charges (corona effect), promotingcapacitance stability over anextremely long period, an essentialin filter circuit applications.

High inrush current withstandcapability is crucialCapacitors used for power factorcorrection undergo a lot of switch-ing operations. The high inrushcurrents that go along with thismust be handled without degrad-ing useful life. The pulse strengthof this technology comes in partic-ular from the enlarged, sensitivecontact area (improved metalspraying). The breakthrough camewith a Siemens patent called thewavy cut, plus heavy edge filmdesign. PhaseCap capacitors caneasily handle inrush currents of upto 200 times rated current.

GeneralThe new PhaseCap HD series is afollow-on development of the MKKAC series, covering the powerrange above 25 through 60 kvarwith just one capacitor in acylindrical aluminum case. ThePhaseCap HD is especially intend-ed for heavy-duty industrial appli-cations with extreme demands foruseful life, constant capacitanceand high inrush current withdstandcapability.

Such applications require typicalpower steps of 25 or 50 kvarswitched by a PFC controller viaeach capacitor contactor. The for-mer series was limited to 25 kvar.The new MKK AC series was devel-oped to increase packing densityper bank and cut componentcosts.

This is a first-time implementationof 60 kvar with only one capacitorin a cylindrical aluminum case,improving thermal response andsimplifying installation.

Technical Data

High inrush current withstandcapability is crucialCapacitors used for power factorcorrection undergo a lot of switch-ing operations. The high inrushcurrents that go along with thismust be handled without degrad-ing useful life. The pulse strengthof this technology comes in partic-ular from the enlarged, sensitivecontact area (improved metalspraying). The breakthrough camewith a Siemens patent called thewavy cut, plus heavy edge filmdesign. PhaseCap HD capacitorscan easily handle inrush currents ofup to 200 times rated current.




Extended useful life of 130,000 operating hoursAfter a long drying phase in a highvacuum to eliminate moisture fromthe active element, the capacitor isimpregnated. The case is filled withinert gas and sealed. Then routinetest are performed for gas leakage.

Technical Data

High inrush current withstandcapability is crucialCapacitors used for power factorcorrection undergo a lot of switch-ing operations. The high inrushcurrents that go along with thismust be handled without degrad-ing useful life. The pulse strengthof this technology comes in partic-ular from the enlarged contact area(heavy edge metalization) andmetal sprayed contact (face side ofwinding element).


contactors

Useful life up to 100,000 operating hoursAfter a long drying phase in a highvacuum to eliminate moisture fromthe active element, the capacitor isfilled with biodegradable soft resin.

This production process helps toavoid oxidation and partial dis-charges, promoting capacitancestability over a long period.

PhiCap is a self-healing, metalizedpolypropylene film capacitor. Thecurrent carrying AlZn metal layer(the best alloy for an electrode) is vapor-deposited onto one side of the film, the surface of thedielectric.

Compact design – low weightand volumeThe entire three-phase capacitor iscomposed of three single-phaseelement stacks. The electrodes areconnected by metal spraying theface ends of the winding elements.The winding elements are encapsu-lated in a cylindrical aluminum caseand hermetically sealed by a press-rolled metal lid or plastic disk withfast-on terminals.

Dual safety systema Self-healing: the capacitor repairs

itself after overload. Self-healingcapability prevents permanentdielectric breakdown in theevent of sporadic voltage surges,overcurrent or overtemperature.

a Overpressure disconnector: thisprevents the capacitor frombursting at the end of its usefullife or through electrical or ther-mal overload. In the event ofpermanent self-healing attemptscaused by repetitive, very highpeak voltages or other overload,there can be permanent break-down. The safety switchingdevice is then activated and dis-connects the capacitor windingelements from the power sourceby an internal pressure increase(expansion of the capacitor case).

Design tipBecause of the increase in capacitorheight on breakdown, it is neces-sary to provide enough clearanceabove the capacitor terminals.

Connection technologya Simplified parallel connection of

capacitors (double fast-on termi-nal or double wire clampingscrew terminals).

a Discharge resistors alreadymounted; standard for extrareliability and safety.

a Cable connection layout (termi-nals) for secure, safe clamping ofrequired cable cross-section.

PhiCap selectionWhen specifying and selectingcapacitors for PFC, there are severalfactors affecting peformance anduseful life:a Voltage,a Harmonics,a Temperature,a Load (overcurrent),a Inrush current.Permanent overvoltage shortens theuseful life of a capacitor. The capaci-tor's nominal voltage must be equalto or greater than the operatingvoltage of the circuit the capacitorwill be connected to.

Harmonics produce overvoltageand overcurrent on capacitors. If thetotal harmonic distortion level forvoltage exceeds 5% for example,serious damage can be caused by

circuit resonance. In such cases,series reactors (detuning) are recom-mended.

Operation of capacitors above theupper category temperature willaccelerate degradation of the dielec-tric and shorten the capacitor's use-ful life.

Residual voltage should not exceed10% of rated voltage whenreswitching capacitors. During thecharging period of capacitors thecurrent is very high – in automaticcapacitor banks it is very likely thatdischarged capacitors will be con-nected to charged ones already con-nected to the grid. In such cases themaximum admissible transient peakcurrent is 100 * IN.

During the switching process, ther-mal and electrodynamic stress isproduced by transient overcurrentsof high amplitude and frequencyand may damage the system.Capacitor contactors with precharg-ing resistors or series inductance(twinned cables between contactorand capacitor) will avoid excessivetransient currents.

SquareCap™ AC Capacitors

GeneralThe SquareCap (metalizedpolypropylene) capacitor series isdesigned for power factor correc-tion in low-voltage plants.

The power range is 1 through60 kvar for a single capacitorcontainer. PFC capacitor modulesare available for single- or three-phase applications in regular orheavy-duty design. Modulescontain the required number ofsingle-phase capacitors in deltaconnection. The capacitors arehoused in a single rectangularsteel case and are connected tothree offset screw terminals (ter-minal block). This constructionenables simple and inexpensiveinstallation on site and savesinventory costs on spares.

WindingThe metalized polypropylene film(MPP) is manufactured inhouse on machines of the latest tech-nology. It consists of two sheets ofpolypropylene film, each with athin layer of silver-zinc-aluminumalloy on one side. Heavy edgeconstruction of the films providesbetter bonding between the elec-trode and the metal spray area toincrease current carrying capabili-ty. It also ensures better resistanceto the electromechanical stressthat occurs in switching surges.

The windings themselves are cen-tered inside the can and sealedwith polyurethane resin. In thisway ionization and corona dis-charge are eliminated, resulting incapacitors of highly stable charac-teristics and long useful life.

High-temperature capabilityThe low dissipation of MPP filmcombined with the superiorthermal conducting properties ofpolyurethane permits operation at temperatures up to 80°C hotspot temperature.

Inductor coilsFor ratings of 6 kvar and higher,each single-phase capacitor isprovided with an inductor coil(mounted between the offsetterminal and capacitor terminal) to control inrush current to thecapacitor, particularly for parallelswitching and automatic controlapplications. This feature ensureslongterm stability of the kvaroutput and extended life.

Discharge resistorAll modules are provided withresistors to discharge the modulesaccording to IEC requirements tovoltages below 75 V within 3 min(IEC 831-1). As a safety precau-tion, all capacitor terminals mustbe shortcircuited before handlingthem.

Triple safety systemSelf-healing technology, over-pressure disconnector andpolyurethane impregnationtechnology contribute to reliableand safe PFC capacitor products.

MKV Cap AC Capacitors

Construction and characteris-tics of MKV capacitorsThe winding element of the MKVAC capacitor consists of polypropy-lene film and paper. The paper layers, carrying metallayers on each side, are separatedby a polypropylene film, serving as dielectric. This winding construction con-tributes to achieve extremely lowlosses and highest pulse currentwithstand capability. For impregna-tion of the capacitor, oil on veg-etable base is used. The oil impreg-nation enables extremely goodheat dissipation from the windingelement to the aluminum can’ssurface, thus preventing hot spotsin the winding element.The capacitor is designed to coverambient temperatures of up to70°C max.

of capacitorsa Reduced lossesa Shockproof case for rail mounting

a PrincipleThe losses of discharge reactorsare substantially lower than thoseof discharging resistors. This isvery important in modern powerfactor correction with high powerdensity because the useful life ofPFC capacitors depends verymuch on ambient temperature.

Discharge reactors satisfy therequirement for permanentlyconnected discharging devicesand for a discharge time of a fewseconds.Because of its high AC resistance,discharge reactor B44066-E9900-S001 only generates extremelysmall losses during operation ofthe capacitor. When capacitors are turned off, there is very fastdischarge over the low DCresistance.

Fast discharging allows a fast re-switching in automatic PFCequipment.

a Power factor correction

To achieve optimum power factorcorrection, a PFC system has to bedesigned according to the re-quired demand on reactive power.The best method is to performactive and reactive power mea-surement prior to the design.Measurements have to cover allimportant time periods duringday- and nighttime to obtainreliable values for peak reactivepower requirements.

PFC formulas (active, reactive,apparent power)

a Active power

The amount of input powerconverted into output power istermed active power and general-ly indicated by P in watts [W] anddefined by the following formula:

P = 3 · U · I · cosϕ [W]

The entire input power, eg appar-ent power, should be convertedinto useful output power stated asactive power, eg the real motorpower output. The quality of sucha power conversion is indicated ascosϕ, the unity power factor.

a Reactive power

Electrical machines work on theprinciple of conversion of electro-magnetic energy (eg electricmotors, transformers). Part of theinput energy is consumed tocreate and maintain the magneticfield. Inductive consumers shift theangle between voltage and cur-rent (to a value > 0). Power creat-ed by portions of V and I wave-forms having opposite directions(+ and –) is called reactive power.This part of the energy (magneticreversal energy), defined as reac-tive power Q in volt ampere reac-tive [var], cannot be convertedinto active power and is returnedto the electrical supply networkduring changes of the magneticfield. But the same amount ofenergy will be consumed by thenetwork again and required forthe next change of the magneticfield.

Q = 3 · U · I · sinϕ [Var)

a Apparent PowerIn principle, applications of electri-cal equipment are based on con-version of electrical energy intosome other form of energy. Theelectrical power drawn by equip-ment from the source is termedapparent power, indicated by S involt ampere [VA], and consists ofactive and reactive power.

S = 3 · U · I [VA)

a Power factorElectrically, the power factor (indi-cated by k) of an electrical circuit isdefined as the cosine of the phaseangle between the fundamentalof voltage and current waveforms.Another definition of power factoris the ratio between active powerand apparent power.

power factor cosϕ = active power / apparent power = P / S

a Reactive power compensation Magnetic reversal energy suppliedto the network (reactive power) incircuits without compensation canbe stored temporarily in capacitorsand then used for the nextchange of magnetism, ie circuitswith reactive power compensa-tion. To calculate the requiredcapacitor reactive power QC in volt ampere reactive [var], thefollowing formula is used:

QC = P · (tanϕ1 – tanϕ2) [var]

A capacitor of QC kvar will com-pensate the inductive Q and com-pensate to cosϕ = 1. It is not com-mon practice to produce cosϕ =1by installation of capacitors since itmay result in overcompensationdue to load changes and responsetime of the controller. Generally,public utilities or power compa-nies specify a value (cosϕ2) towhich the existing power factor(cosϕ1) should be corrected.

a Connection and rating of capacitors

A general expression for the kvarrating of a capacitor:

QC = UC · IC [Var]

UC · UC (UC)2QC = –––––––– = –––––

XC XC

1 1XC = ––––– = ––––––––– · C 2 · f · C

QC = (UC)2 · · C = (UC)2 · 2 · f · C

a Capacitor in single-phase PFCapplication

The capacitor is connected acrossthe phase and neutral and issubjected to the phase neutralvoltage (see above).

a Capacitor in three-phase PFCapplication

STAR connection

The capacitor is subject to avoltage of (UL / 3).

Thus total kvar compensation iscalculated as:

(UL)2QTOT = 3 · –––––– · · C

(3)2

QTOT QTOTCSTAR = ––––––––– = –––––––––––––(UL)2 · (UL)2 · 2 · f

DELTA connection

The capacitor is subjected to linevoltage UL, phase to phase.

Thus total kvar compensation iscalculated as:

QTOT = 3 · (UL)2 · · C

QTOT QTOTCDELTA = –––––––––– = ––––––––––––––3 · (UL)2 · 3 · (UL)2 · 2 · f

As a conclusion one can say:

CSTARCDELTA = –––––3

So PFC configurations are usuallydelta connected because star con-nection requires three times thecapacitance of a delta connection.

a Apparent power transmission

Due to the power factor correc-tion, the required apparent powertransmission can be reduced bythe value S1 – S2.

S1 uncompensated load:S1 = P / cosϕ1 = 220 / 0.7 =

= 314 kVA

S2 compensated load:S2 = P / cosϕ2 = 220 / 0.9 =

= 244 kVA

Reduction of apparent power aftercompensation:

S1 – S2 = 70 kVA

Thus, additional power of 70 · (0.9) = 63 kW can be supplied and transferredvia the existing network.

The power losses decrease withthe square of the current.PU1 – PU2 = I12 – I22

= approx. S12 – S2

The resistive transmission losses(power loss) PU are reduced by:

(S12 – S2

2) · 100% =S1

[(314)2 – (244)2] · 100% = 39.6%(314)2

a Cable cross section calculation

Line current drawn by the motor:

I1 uncompensated load (0.7):

220 · 1000I1 = ––––––––––––––––– = 412 A3 · 440 · (0.7)

I2 compensated load (0.9):

220 · 1000I2 = ––––––––––––––––– = 320 A3 · 440 · (0.9)

Thus, the cable can carry anadditional load of 92 A, or thedesigner can reduce the cablecross section.

Example 2:

Given parameters:

– Active powerP = 100 kW (peak)

– Actual cosϕ= 0.75 = ϕ = 41.5° = tanϕ1 = 0.88

– Target cosϕ*= 0.93 = ϕ = 21.5° = tanϕ2 = 0.4

* set by power utility

Calculation of compensation:

QC = P · (tanϕ1 – tanϕ2)= 100 · (0.88 – 0.4)= 48 kvar

to be compensated to meet thepower factor requirement set bythe power utility. Common com-pensation would recommend acapacitor of at least 50 kvar.

Calculation using capacitor’sreactive power QC table:

cosϕa (actual) = 0.75*cosϕt (target) = 0.94** the cross point indicates factor

F = 0.52

QC = P · F = 100 · 0.52 = = 52.0 kvar

The required appropriate compen-sation to meet cos ϕ = 0.93 is≥ 52.0 kvar

Installation and Maintenance

Mounting

Power capacitors should be installed in a cool and well ventilated location, and notclose to objects that give off heat, like filter circuit reactors and furnaces, or in directsunlight.

Leave enough spaceon top of the capaci-tor and do not fix anymounting compo-nents at the crimp oron top to allow longi-tudinal expansion ofthe can and properfunctioning of theoverpressure discon-nector.

The M12 stud also serves for grounding.Connect to ground or connect the capaci-tor to other conductive items that aregrounded. Note that suitable connectorsmust penetrate existing layers of lacquerto achieve good and constant conductionand sufficient current carrying capability.

Tighten the threaded M12 stud on the bottom of the case with 10 Nmtorque.

A minimum spacingof 20 mm is neces-sary between capaci-tors to ensure propercooling.

≥ 20 mm

≥ 20 mm

PhaseCap, WindCap:any mounting position of the capacitoris possible, vertical and horizontal.

Remember to ensure sufficient cooling.

Capacitors installed in a cabinet should be at the bottom to ensure the leasttemperature stress.

Discharge resistorsa Discharge resistors are required to discharge capacitors and protect humans

against electric shock hazard as well as to switch capacitors in automatic PFCequipment (opposed phase).

a EPCOS discharge resistors are designed to discharge capacitors to 75 V or lesswithin 60 s.

a Before switching again, capacitors must be discharged to 10% or less of nominalvoltage.

a Discharge resistors are included in delivery.

Notea Discharge resistors must not be configured between a connecting cable and the

top of the capacitor – shortcircuit risk.a Make sure resistors are firmly clamped and that there is enough space between

resistors and between them and metallic parts of the capacitor case.

Ambient temperatureCapacitors are divided into tem-perature classes. Each class is represented by a number followedby a letter, eg –40/D. The numberis the lowest ambient temperatureat which a capacitor may operate.The upper limit temperature isindicated by the letter, D standingfor 55°C. Higher ambient temper-ature is possible by forced cooling.A maximum case temperature of60°C must not be exceeded. Tem-perature is one of the main stressfactors for polypropylene capaci-tors, having a major effect on theiruseful life. For higher temperaturerequirements up to 70°C (withnatural cooling) MKV capacitorsfrom EPCOS should be selected.

Inrush currentSwitching LV PFC capacitors, espe-cially when they are in parallelwith others that are already ener-gized, can cause high inrush cur-rents of up to 200 times nominalcurrent. This leads to additionalstress on contactors as well ascapacitors and reduces their usefullife. Plus, high inrush currentshave a negative effect on powerquality, producing transients andvoltage drops for example.

Although the MKK AC design withits wavy cut exhibits excellentpulse withstand capability, limita-tion of inrush current is still recom-mended, eg:

a contactors with prechargingresistors,

a serial air coils (approx. eightturns in the connecting cablebetween contactor and capaci-tor with a diameter of 10 cm).

For more information on this sub-ject, refer to the EPCOS applica-tion report "Damping of inrushcurrents in LV PFC equipment".

HarmonicsHarmonics are produced in theoperation of electric loads with anonlinear voltage/current charac-teristic (eg rectifiers and invertersfor drives, welding apparatus anduninterruptible power supplies).Harmonics are sinusoidal voltagesand currents with higher frequen-cies of a multiple of the 50 or60 Hz line frequency.Note: In applications subject toharmonics, you should only usepower capacitors with reactors,socalled detuned capacitor banks.Depending on the selected seriesresonant frequency, part of theharmonic current is absorbed bythe power capacitor. The remain-der of the harmonic current flowsinto the superordinate system. Theuse of power capacitors with reac-tors reduces harmonic distortionand lessens the disturbing effecton proper operation of other elec-tric loads.

A major reason for installingdetuned capacitor banks is toavoid resonance. This can multiplyexisting harmonics and createpower quality problems, as well ascausing damage to distributorequipment.

For more information on thissubject, refer to the EPCOS appli-cation report "Harmonics andremedial measures in LV PFCequipment".

Safetya Ensure good, effective ground-

ing for capacitor enclosures.a Provide means of disconnecting

and isolating a faulty compo-nent/bank.

a Handle capacitors carefully,because they may still becharged even after disconnec-tion due to faulty dischargingdevices.

a Follow good engineering prac-tice.

a Do not use HRC fuses to powera capacitor up and down (riskof arcing).

a Remember that the terminals ofcapacitors, connected bus barsand cables as well as otherdevices may also be energized.

Overcurrent and shortcircuitprotectiona Use HRC fuses or MCCBs for

shortcircuit protection. Shortcir-cuit protection and connectingcables should be selected sothat 1.5 times the nominalcapacitor current can be perma-nently handled.

a HRC fuses do not protect acapacitor against overload –they are only for shortcircuitprotection.

a The HRC fuse rating should be1.5 to 1.8 times nominal capaci-tor current.

a Do not use HRC fuses to switchcapacitors (risk of arcing).

100 EPCOS AG

MKK AC capacitors are mainte-nance-free, but regular servic-ing will ensure reliable andsafe operation for the full lifecycle:a Periodically check that connec-

tions and terminals are tight.a Regularly clean terminals/bush-

ings to avoid shortcircuits dueto dust and soiling.

a Check shortcircuit protectionfuses.

a Make a current reading twiceannually to see if applicationconditions have altered.

a Consider upgrading or modi-fying the PFC system if theapplication environment haschanged.

a In the event of a current abovenominal, check your applicationfor possible modification.

a In the event of a significantincrease in nonlinear loading,call in a consultant for a har-monics examination.

a If harmonics are present, con-sider installation of a detunedcapacitor bank (reactors).

a Check discharge resistors/reac-tors and their functioning:– Power the capacitor up and

down.– The voltage across the termi-

nals must fall to < 75 V within60 s.

Selection of connecting cablecross-section, HRC fuse ratingThe cross-section figures below areguidelines for operation in normalconditions at ambient tempera-tures up to 40°C. Upgrade accord-ingly if conditions, eg temperatureor harmonics, differ.The internal wiring of a capacitorbank is normally possible with asmaller cross-section. Various para-meters such as temperature insidethe cabinet, cable quality, maxi-mum cable isolation temperature,single- or multi-core cable andcable length have to be consid-ered for proper selection.
