Brief description of device

The UMG 96 RM-E is a multi-functional net-

work analyser, which

• measures and monitors residual currents

(RCM) and currents at the central grounding

point (CGP). The residual current monitoring

is carried out via an external residual current

transformer (30 mA rated current) on the

current measurement inputs I5 and I6.

• measures and calculates electrical variables

such as voltage, current, power, energy,

harmonics, etc. in building installations,

on distribution units, circuit breakers and

busbar trunking systems.

• displays and saves measurement results

and transmits them via interfaces.

NOTE!

If residual currents in electrical systems

are monitored, the device (inputs I5/I6)

can trigger warning pulses if a response

threshold is exceeded. The warning pulses

can provide an alarm before a protective
