NWE FPI

NWE FPI is designed to detect and indicate Earth fault (phase-to-ground) and Short circuit faults (phase-to-phase) on overhead distribution lines. The unit will indicate a fault condition when current is detected above set trip current settings and fault information is instantaneously sent to the central server for further actions. This enables the operator at dispatch center to immediately identify the fault location and quick actions can be taken to recover power outage.

If the current exceeds programmed set current for programmed response time (i.e. if fault occurs for t>= response time) the fault will be indicated by flashing LED. Reset occurs automatically by preset time passage (adjustable) or manually on-site or can be done remotely from data centre. Configurable parameters need to be programmed at the time of installation thus avoiding unauthorized field tampers.
