CSFPI, Fault Passage Indicator — Earth is designed to detect and indicate Earth fault on a cable system, in RMU networks with one input / open ring arrangement. The unit will indicate a fault condition when current is detected above set trip current settings. Fault current is sensed by cable mounted sensor, which gives signal to indication unit. Sensor must be mounted on screened cable and can be retrofitted on the cable.
