Fault passage indicator

Listing ID #4227528

The main function of fault passage indicating system is to identify faults occurring in the downstream section from the point of its installation in the medium voltage system. This is achieved by continuous monitoring of voltage presence and current flow in medium voltage line.

Any increase in current along with absence of voltage is signaled by the equipment. Fault condition is indicated by flashing lights in FPI; this information is sent using radio signals to the communication gateway installed nearby for onward transmission to SCADA system at the control centre through a suitable communication channel.

Using this system, the utility acquires information regarding the section of the line having fault. This identification helps eliminate the patrolling of entire line for finding the fault, ultimately reducing restoration time.
