Line Fault Indicator

1. High level of accuracy. 2. Stable operation. 3. Automatic reset function. 4. Easy installation and maintenance-free.

Line Fault Indicator (earthing and short-circuit faults)

Fault Indication: during normal operation, the window displays in white. When short-circuit fault and grounding fault happen, window displays in red. The light will be on at night if there is a fault happens.

Online operation: directly installed on the overhead network and no maintenance.

Good Adaptability: automatic verdict.

Strong anti-jamming: the circuit, excitation rush current, and ultra harmonics don’t affect signal, especially the capacitance bypass of cable distribution.

Automatic Reset: after the indicator change the card in the window, current transmission is automatically reset through the current impact, without setting time.

Assembling and Disassembling With Power: no influence to the operation of network.
