VOLVO PENTA GENSET ENGINE

TAD532GE1500 rpm, 127 kW (172 hp) – 1800 rpm 132 kW (179 hp)

The TAD532GE is a powerful, reliable and economical Generating Set Diesel Engine.

Durability & low noiseDesigned for easiest, fastest and most economical installation. Well-balanced to produce smooth and vibration-free operation with low noise level. To maintain a controlled working tem-perature in cylinders and combustion chambers, the engine is equipped with piston cooling. The engine is also fitted with replaceable cylinder liners and valve seats/guides to ensure maximum dura-bility and service life of the engine.

Low exhaust emissionThe state of the art, high-tech injection and charging system with low internal losses contributes to excellent combus-tion and low fuel consumption. The TAD532GE is certified for EU Stage 2 exhaust emission regulations.

Easy service & maintenanceEasily accessible service and mainte-nance points contribute to the ease of service of the engine.

Power StandardsThe engine performance corresponds to ISO 3046, BS 5514 and DIN 6271. The technical data applies to an engine without cooling fan and operating on a fuel with calorific value of 42.7 MJ /kg (18360 BTU/lb) and a density of 0.84 kg/liter (7.01 lb/US gal), also where this involves a deviation from the standards. Power output guaranteed within 0 to +2% att rated ambient conditions at delivery. Ratings are based on ISO 8528.Engine speed governing in accordance with ISO 3046/IV, class A1 and ISO 8528-5 class G3Exhaust emissionsThe engine complies with Tier 2 and TA-luft exhaust emission regulations.

Rating GuidelinesPRIME POWER rating corresponds to ISO Standard Power for continuous operation. It is applicable for supplying electrical power at variable load for an unlimited number of hours instead of com-mercially purchased power. A10 % overload capability for govering purpose is available for this rating. MAXIMUM STANDBY POWER rating corresponds to ISO Standard Fuel Stop Power. It is applicable for supplying standby electrical power at variable load in areas with well established electrical networks in the event of normal utility power failure. No overload capability is available for this rating. 1 hp = 1 kW x 1.36InformationFor more technical data and information, please look in the Gener-ating Set Engines Sales Guide.

STANDARDSNewage Stamford industrial generators meet therequirements of BS EN 60034 and the relevant sectionof other international standards such as BS5000, VDE0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.Other standards and certifications can be considered onrequest.

VOLTAGE REGULATORS

SX460 AVR - STANDARDWith this self excited control system the main statorsupplies power via the Automatic Voltage Regulator(AVR) to the exciter stator. The high efficiencysemiconductors of the AVR ensure positive build-upfrom initial low levels of residual voltage.The exciter rotor output is fed to the main rotor througha three phase full wave bridge rectifier. This rectifier isprotected by a surge suppressor against surges caused,for example, by short circuit.

SX440 AVRWith this self-excited system the main stator providespower via the AVR to the exciter stator. The highefficiency semi-conductors of the AVR ensure positivebuild-up from initial low levels of residual voltage.The exciter rotor output is fed to the main rotor througha three-phase full-wave bridge rectifier. The rectifier isprotected by a surge suppressor against surges caused,for example, by short circuit or out-of-phase paralleling.The SX440 will support a range of electronicaccessories, including a 'droop' Current Transformer(CT) to permit parallel operation with other acgenerators.If 3-phase sensing is required with the self-excitedsystem, the SX421 AVR must be used.

SX421AVRThis AVR also operates in a self-excited system. Itcombines all the features of the SX440 with,additionally, three-phase rms sensing for improvedregulation and performance. Over voltage protection isprovided via a separate circuit breaker. An engine reliefload acceptance feature is built in as standard.

MX341 AVRThis sophisticated AVR is incorporated into theStamford Permanent Magnet Generator (PMG) controlsystem.The PMG provides power via the AVR to the mainexciter, giving a source of constant excitation powerindependent of generator output. The main exciteroutput is then fed to the main rotor, through a full wavebridge, protected by a surge suppressor. The AVR hasin-built protection against sustained over-excitation,caused by internal or external faults. This de-excites themachine after a minimum of 5 seconds.An engine relief load acceptance feature can enable fullload to be applied to the generator in a single step.If three-phase sensing is required with the PMG systemthe MX321 AVR must be used.We recommend three-phase sensing for applicationswith greatly unbalanced or highly non-linear loads.

MX321 AVRThe most sophisticated of all our AVRs combines all thefeatures of the MX341 with, additionally, three-phaserms sensing, for improved regulation and performance.Over voltage protection is built-in and short circuitcurrent level adjustments is an optional facility.

WINDINGS & ELECTRICAL PERFORMANCEAll generator stators are wound to 2/3 pitch. Thiseliminates triplen (3rd, 9th, 15th …) harmonics on thevoltage waveform and is found to be the optimumdesign for trouble-free supply of non-linear loads. The2/3 pitch design avoids excessive neutral currentssometimes seen with higher winding pitches, when inparallel with the mains. A fully connected damperwinding reduces oscillations during paralleling. Thiswinding, with the 2/3 pitch and carefully selected poleand tooth designs, ensures very low waveformdistortion.

TERMINALS & TERMINAL BOXStandard generators are 3-phase reconnectable with 12ends brought out to the terminals, which are mountedon a cover at the non-drive end of the generator. Asheet steel terminal box contains the AVR and providesample space for the customers' wiring and glandarrangements. It has removable panels for easyaccess.

SHAFT & KEYSAll generator rotors are dynamically balanced to betterthan BS6861:Part 1 Grade 2.5 for minimum vibration inoperation. Two bearing generators are balanced with ahalf key.

INSULATION/IMPREGNATIONThe insulation system is class 'H'.All wound components are impregnated with materialsand processes designed specifically to provide the highbuild required for static windings and the highmechanical strength required for rotating components.

QUALITY ASSURANCEGenerators are manufactured using productionprocedures having a quality assurance level to BS ENISO 9001.

The stated voltage regulation may not be maintained inthe presence of certain radio transmitted signals. Anychange in performance will fall within the limits ofCriteria 'B' of EN 61000-6-2:2001. At no time will thesteady-state voltage regulation exceed 2%.

NB Continuous development of our products entitles usto change specification details without notice, thereforethey must not be regarded as binding.
