JYZ-HW-FI Remote Overhead Line Fault indicator
The earth-fault and short-circuit fault indicator type JYZ-HW-FI V1.0 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 three ultra-bright blinking LEDs, which can be seen from 360º sight.

The earth-fault and short-circuit fault indicator type JYZ-HW-FI V1.0 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 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.


The indicator can be mounted under live conditions with the help of an adapter and a hot stick. The parameters such as trip current, reset time, blinking interval, etc., can be read and adjusted by a bidirectional wireless tool. Permanent fault, instantaneous fault, and battery low warning can be distinguished and indicated separately by three different ultra-bright blinking LEDs. And the earth-fault can be indicated by two alternating different ultra-bright blinking LEDs.


The earth-fault and short-circuit fault indicator type JYZ-HW-FI V1.0 consists of:
1 pc DCU: Optional, transmission fault and load current value to SCADA
3 pc indicators: short-circuit and earth fault detection and indication
