Overhead transient characteristic remote fault indicator

model：JYZ-DX

1、 Demand analysis

High voltage transmission line, due to its long distance and complex terrain across the region, is the place where power system failures occur frequently. It is very important to quickly and accurately locate the fault location of high voltage transmission line to restore power supply and ensure the safe and economic operation of power system. The overhead transient characteristic remote fault indicator has the functions of line load monitoring, short circuit fault and ground fault indication, which can help the line finder quickly find the fault point, shorten the outage time and improve the power supply reliability. The product is made of high-strength materials, which are formed in one time, with high hardness, good perspective, anti pollution, anti-oxidation, long service life and maintenance free.

2、 Working principle

The equipment monitors the load of the line when there is no abnormal operation of the line. When the equipment detects faults such as interphase short circuit and ground fault on the line, it can carry out local sign flipping indication and LED flashing, and upload the detection information to the master station system in real time through the communication terminal to help the operation and maintenance personnel quickly determine the fault point, conduct fault handling, shorten the power outage time, and greatly improve the stability of power supply.
