Testermeter- JYZ-FF Overhead Live Line Flag Fault indicator
| JYZ-FF Flag fault indicator is an electronic fault detection device specially designed for medium voltage power distribution overhead lines. They are suitable for overhead power distribution lines <110KV. The JYZ-FF Flag fault indicator has a load self-adaptive function, which can adjust the fault tripping threshold according to the load change on site. Cooperating with the remote control unit DCU, Flag Fault indicator can realize remote and fast acquisition of fault information. The unique mechanical signs can be quickly identified even 100m away during the day, and the bright LED lights at night have a 360° viewing angle, which can quickly locate the fault point 500m away. |
