Underground Fault indicator DYO-FF-FIS is a Four-Faith underground cable fault indicator family used in environments with higher precision requirements. The sensor based on the Rogowski coil has better sensitivity and supports the detection of short-circuit ground faults. It has self-test and self-recovery functions. Underground Fault indicator is suitable for 5-38KV power distribution ring network lines. Installed in substation cable outlets, RMU reduces fault location time and provides safety for public utility workers.
The display panel adopts wall-mounted installation, which is simple and fast, and the sensor adopts threaded interface to quickly lock the cable
Remote access to SCADA
Minimize the fault finding time, without opening the high-voltage cabinet, reducing personnel investigation
Manual, time, automatic, remote Custom time reset, 12h, 24h to ensure enough time to find faults
Based on Rogowski coil sensor, the accuracy can reach ±5%> When 100A, the protection level meets IP65
