Four-Faith Overhead Line Fault Indicators are usually used in radial medium and high voltage overhead line distribution networks, which neutral points are ineffectively grounded. Short-circuit fault and single-phase earthed fault can be detected and indicated by mechanical flag and three ultra-bright blinking LEDs, which can be seen from 360º sight. The fault information and load current value can also be transmitted to the SCADA by 2G/3G/4G networks.
