Fault Passage Indicator

SICAM Fault Passage Indicator (FPI) is a device that is used for detection and signalling of short circuit and earth-fault on medium voltage cable networks.4 external current sensors detect the phase faults (R, Y, B) and earth-fault (E).The current sensor detects phase fault and earth-fault current based on the set current threshold detection and communicate to SICAM FPI via an optical signal.By using the rotary switch available on the individual sensor, you can set the fault current threshold for phase sensors from 200 A to 1200 A (Type 1 Series), 200 A to 800 A (Type 2 Series) and for earth sensor from 10 A to 100 A (Type 1 Series), 40 A to 300 A (Type 2 Series).When the current exceeds the set threshold level, the current sensor provides an input via plastic fibre-optic cable to SICAM FPI. In this condition, the corresponding LEDs blink. In normal operating condition, there is no LED indication.SICAM FPI is used as a fault detection and indication unit. SICAM FPI is used in the feeder and distribution automation of secondary medium-voltage systems that ranges from 10 kV to 36 kV.
