JJZ-FF Overhead Line Fault Indicator Overhead Fault Indicator, Line Fault Indicator

JJZ-FF Overhead Line Fault Indicator is usually used in 5~38KV overhead line power distribution network to monitor and detect short-circuit and earth fault. The fault is indicated by mechanical flag and three ultra-bright blinking LEDs with 360º sight.The indicator can be mounted under live conditions with the help of an adapter and a hot stick. The trip current and reset time can be set by dial switches during production. And battery low voltage warning can be distinguished and indicated by red mechanical flag.
