Janitza UMG96RM-E Digital rack-mount meter 6-channel network analyzer UMG 96 RM-E, Ethernet, with RCM measurement

The UMG 96 RM-E measuring devices have 6 current inputs (4 inputs to 1 or 5 A and 2 analogue inputs 0 - 30 mA), of which the 2 analog inputs for temperature or differential current measurement can be used. A continuous monitoring of the current difference in power distribution is so in addition to the normal measurement of the operating currents. A special procedure for the RCM-measurement was implemented, with the rcm limits in relation to the total power dynamically. With the dynamic limit value formation is in all load areas a customized differential current limit value is calculated and unnecessary error alarms are avoided. In contrast to conventional RCM monitoring devices, even in small load range, an optimum fault current limit value is guaranteed. Flowing fault currents and leakage currents to ground according to IEC 60755, type A and B registered and recorded, for example, consumers in infeeds, or central grounding points.
