Residual current monitoring

The residual current monitoring (RCM) plays an increasingly important roll for applications with a demand for highly available power supplies. With a continuous residual current monitoring, you have control over your low voltage network. Dangerous residual currents, which can lead to system faults or increase the risk of fire are detected immediately so that a production losses can be avoided.

Further information and the detailed RCM white paper can be found at: https://www.janitza.com/whitepaper-about- rcm.html

BENEFITS OF A RESIDUAL CURRENT MONITORING


RCM measurement devices from Janitza, such as the UMG 512-PRO / UMG 509-PRO / UMG 96RM-E / UMG 96-PA / UMG 96RM-PN, UMG 20CM, are suitable for monitoring alternating currents and pulsating direct currents according to IEC/TR 60755 (2008-01) (type A and type B), and can be used for constant review of residual currents in TN-S systems.

Application possibilities can be found in nearly all market segments, particularly when continuous processes and especially sensitive applications are involved. This is how e.g. data centers, hospitals or semiconductor factories rely on RCM monitoring. Wherever insulation resistance measurements and residual current circuit breakers cannot be implemented due to local or operating conditions, RCM measurement provides a good alternative.

ADDED VALUE AND SAVING POTENTIALS Early detection and notification of residual currents

by continuous monitoring Constant review of the intactness of TN-S systems Compliance with EMC and minimization of faults on

grounded electrical equipment and thus an increase in the system availability

Reduced inspection effort on stationary electrical facilities in the context of DGUV regulation 3 for electrical operational safety, IEC 60364-6:2016

Insulation measurements on stationary electrical facilities and the related shutdown can be omitted


PREVENT SYSTEM FAILURES

IMPROVE FIRE PROTECTION

PREVENT PRODUCTION INTERRUPTIONS

REDUCE ENERGY CONSUMPTION(ISO 50001/50006)

OPTIMIZE MAINTENANCE COSTS

MONITOR HIGHLY AVAILABLE ENERGY DISTRIBUTION BOARDS

No danger to sensitive loads which could be damaged by a high test voltage

No high personnel and administrative effort due to shutdowns and thus a reduction of costs

Maximum alternative safety in areas in which no RCDs can be used due to operational reasons

Early warning system for RCDs and ground fault switch High connectivity and retrofitting capability in new

and existing systems Essential for TN-S systems with a demand

for a high availability!

THE MONITORED TN-S SYSTEM


Residual and operating current monitoring: Implementable with network analyzers 512-PRO / UMG 509-PRO / UMG 96RM-E /

UMG 96-PA (with RCM module). The RCM device used should be easy to operate, automatically point out problems and simultaneously

provide service technicians with a valuable tool.

TN-S systems are mandatory for new systems. Even for older TN-C-S systems, retrofitting to TN-S systems is recom-mended. The functionality of TN-S systems can be perma-nently monitored and recorded with Janitza RCM solutions.

This requirement represents a key function for the safety and economic success of a company in many industries and application areas.

In practice, all three phases and the neutral conductor run through the summation current transformer. For systems without a neutral conductor, for example with controlled drives, only the three phases of the summation current transformer are used. When the system is in an error-free state, the total current is zero or almost zero (in the tolerable range) so that the induced current in the secondary circuit is also zero or almost zero. Conversely if,

in the event of an error, a residual current flows to ground, the current difference in the secondary circuit causes a current that is detected, reported and evaluated by the RCM measurement device.

Notification before shutdown – a goal of the residual current monitoringIt is essential to detect faults that arise early on, before fuses or residual current circuit breakers (RCD) of affected systems or socket circuits shut down. The usually gradual increases in residual currents (e.g. triggered due to insulation faults and too high operating currents of system parts or consumers) must be monitored, evaluated and reported for this, before failures arise!

DESIGN OF A RESIDUAL CURRENT MONITORING WITH JANITZA

The Janitza network analyzers allow a modular and flexible system design over the entire power supply. All measurement devices have at least one Modbus RTU interface. Though, depending on the type, also TCP/IP, SNMP, BACnet IP, Profibus, Profinet via Modbus. This allows an integration without complicated diversions via proprietary protocols in already existing BMS. Comprehensive RCM diagnostic variables are available in order to implement an optimal monitoring solution.

The Smart Energy Panel JPC 70 – up to 200 RCM monitoring points are handled in one display


GridVis®

network visualization software

Additionally, all devices can be managed and visualized with the GridVis® network visualization software. Automated RCM test reports facilitate the evaluation and documen-tation requirements.

The Smart Energy Panel JPC 70 can fully manage and display up to 200 RCM monitoring points. It is the tailored solution for a system-related status monitoring.

NETWORK ANALYZER

Secondary distributionThe UMG 96RM-E has 6 current inputs (4 inputs for 1 or 5 A and 2 analog inputs 0...30 mA), wherein the 2 analog inputs can be used for temperature or residual current monitoring. It combines five functions in one compact device: Universal measurement device, energy monitoring, harmonics analysis and power quality and residual current monitoring.

A continuous monitoring of the residual currents in power distribution systems is thereby possible in addition to the normal measurement of the operating currents. A special method was implemented for the RCM measurement,

in which the RCM threshold values are dynamically set according to the total power. With the dynamic threshold value creation, a customized residual current threshold value is created in all load areas and thus unnecessary error alarms are prevented. Unlike conventional RCM monitoring devices, an optimal residual current threshold value is also ensured in the low load range.

Residual currents and leakage currents are detected and recorded to ground according to IEC 60755 type A and B.
