Product Description

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. When detect before fault point, the current will continue but after the fault, the current will can't be tested.
First use this device to find the fault by areal survey, then pinpoint to find the fault point.

3.Function features:
Apply to small current neutral grounding distribution power system. It is used to detect the over head line metallic grounding fault, arc grounding fault, resistance grounding fault and so on.
Workable for broke down line, apply for branch line
Ultralow frequency signal to avoid capacitor influence. Easy to find the high resistance fault
Recreate fault by high voltage signal, easy to locate
Safe transmitter by black and short-circuit function
High sensitive sensor, open design and easy to hang on the line
Wireless transmission, safe and reliable
Flexible power supply. Transmitter is workable by Utility power and electric generator. Sensor and receiver are by dry battery
Light and easy to carry
Receiver has large LCD display interface, which can show the current waveform and current value
