Used for 6-110 kV power transmission and distribution lines
Features
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.
Automatic Reset: after the indicator change the card in the window, current transmission is automatically reset through the current impact, without setting time.
Strong anti-jamming: the circuit, excitation rush current, and ultra harmonics don’t affect signal, especially the capacitance bypass of cable distribution.
Assembling and Disassembling With Power: no influence to the operation of network.
