Product Description
1.Introduction
  Overview: 
Good solution of the pinpointing of single phase to earth fault
It applies to overhead line small current grounding power system.
It is use to pinpoint the earth fault when line break down when single phase grounding fault happen.
The kit includes transmitter (OGFL-200T), senor (OGFL-200S) and receiver (OGFL-200R) and the accessories. 
After the overhead line stop running, the transmitter will inject ultralow frequency HV signal to the line to reappear the fault. Detect along with the line by the sensor and it will transmit data to the receiver by wireless mode. The receiver will collect and display this detect result.
