Early Detection, Maximum Protection
Earth faults are silent threats that compromise both safety and uptime. Chhabi’s ELMS identifies insulation degradation at an early stage, enabling operators to take preventive action before minor leaks escalate into major hazards
Identifies positive and negative ground faults with sensitivity down to 50mA (100mA optional).
Simultaneously supervises up to 8 independent feeders.
Seven-segment LED displays per feeder, with positive/negative indicators.
Modbus RTU/TCP options for SCADA/BMS connectivity.
Includes scan-and-hold function with configurable scan time
