Product description

ZGDJ-X1 distributed fault location system is an advanced lightning monitoring system which is made by ZG Lightning technologies. This
system changes the location of traditional fault locating device from secondary side of substation onto the line to directly get the fault current traveling wave so as to collaboratively analyze several checking points of fault current traveling waves to get actual fault location correctly.
Compared with the traditional fault locating method, distributed fault locating is more approaching to actual status of current traveling wave and is
able to make modification based on calculated datum gained from practical operation status on lines. And this method greatly improves the
locating accuracy. As to info of lightning interference, this system can realize effective identification of lightning strikes through analysis of
time-domain data of lightning current traveling wave, polarity and energy spectrum, which can provide guidance to planning departments to make
targeted lightning protection plan.
The system can quickly determine the fault section and fault location, shorten the time to repair, which greatly improves the reliability of power
supply system and reduce the direct and indirect losses due to power failure.
