    Overview

    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.
