Product Introduction

If you're in need of overhead line distributed fault location monitoring device to help with your business, please be free to buy with our factory. As one of the leading such manufacturers in China, we will offer you low price and unmatched services.

The distributed fault location monitoring system utilizes fault monitoring terminals distributed along transmission lines to obtain traveling wave current, traveling wave transit time, and reflection time at the moment of the fault. This data is transmitted to the system platform via wireless communication technology to accurately determine the fault location. Additionally, intelligent discrimination technology is employed to analyze fault waveform characteristics, identifying whether the fault is caused by lightning or non-lightning factors. When the fault is lightning-induced, the system can further distinguish between "back flashover faults or shielding failure faults," and the diagnostic results are immediately notified to the staff.

Terminal layer:
Use intelligent fault monitoring terminals to obtain traveling wave current, traveling wave transit, and reflection time at the time of the fault, perform preliminary analysis, and filter redundant data.
Network layer:
Use wireless communication technology to transmit data to the system platform and accurately determine the fault location.
Operation and maintenance platform layer:
Use intelligent identification technology to analyze fault waveform characteristics and identify whether the fault is caused by lightning or other factors.
