In the field of power grid operation and maintenance, traditional fault detection often faces the predicament of "searching for a needle in a haystack" - manual inspection is time-consuming and labor-intensive, and the alarm system is noisy and disruptive, with positioning errors often reaching hundreds of meters. However, today, the story has a different script. The HIZ-SD-GCJ power line fault distance measurement device independently developed and designed by Guangxi Haizhuo Technology can be deployed in substations, power plants and other scenarios. The device responds immediately when a fault occurs, eliminating the need for on-site alarms and manual inspections. It can accurately capture the subtle time difference of the fault traveling wave, just like a professional detective, locking onto the root cause of the fault from the current signal.
The device automatically completes the fault location calculation through the collection and analysis of fault signals and sends the results to the operation and maintenance personnel via text message. The fault location accuracy is high, with an error of no more than one tower position. It can achieve rapid and precise distance measurement of faults in 110kV and above voltage level transmission lines, significantly improving the efficiency of power grid operation and maintenance.
