JYL-FF Remote Overhead Line Wave Recording Fault circuit Indicator



The wave record fault circuit indicator type JYL-FF V2.0 is usually used in radial medium and high voltage overhead line distribution networks, which neutral points are ineffectively grounded.

Trial Sample

The wave record fault circuit indicator type JYL-FF V2.0 is usually used in radial medium and high voltage overhead line distribution networks, which neutral points are ineffectively grounded. Short-circuit fault and single-phase earth fault can be detected and indicated by four ultra-bright blinking LEDs, which can be seen from 360º sight. The voltage and current wave can be recorded at all time, especially when the voltage drop or the current change suddenly. The wave records in the forms of IEEE Comtrade 1999 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. One DCU can link at most nine indicators.
The wave record fault circuit indicator type JYL-FF V2.0 consists of:

1 pcs DCU: transmission fault, load current value and wave record to SCADA
3 pcs indicators: fault detection and indication, and wave recording
