NGRM7xx_D00292_07_M_XXEN/02.2022

3. Function

3.1 Device features

 Determination of R

NGR

with passive and active measurement methods

 Continuous monitoring of the R

NGR

even if the installation is de-energized;

 Alarm or trip on ground fault

 Monitoring of the current I

NGR

 Monitoring of the voltage U

NGR

 Faulted phase indication (optional; up to 690 V direct coupling, otherwise via poten-

tial transformers)

 Ethernet communication

 Web server

 Language selection (German, English GB and US, Spanish, French)

 Test button (internal, external) with/without tripping

 FFT analysis of neutral current and voltage

 Pulser control for manual ground fault location

 Relay outputs for detection of ground faults and resistor faults

 Relay output for shutdown of the installation after a configurable time

 Can be combined with RCMS… for automatic shutdown of feeders

 Graphical user interface

 Integrated wide-range power supply unit for operating the NGR monitor

(AC/DC 24…240 V)

 Range of use up to 5000 m AMSL

 Fault/History memory

 Analogue output of measured values (0…10 V, 4…20 mA, etc., selectable parameter)

 Detachable HMI for door mounting

 Password protection

 Tripping on RMS, fundamental component signal or harmonics

 Detection of AC and DC ground faults
