Benefits of technology

This patented technology helps detect if there are any problems with an electricity supply network caused by equipment or other issues during operation without being able to identify which problem it's causing itself.

Problems solved by technology

This patented describes how to detect if there are any disruptions or failures on electricity transmission lines that may lead to accidents such as fires caused by overvoltage conditions during periods when no electrical current flows through them (a type called direct) without causing damage.

Abstract

The invention provides a distribution line fault detection system. The distribution line fault detection system comprises a signal acquisition unit, a signal conditioning unit, a control processing unit, a display unit, an alarm unit, a communication unit and a circuit breaker control instruction output unit. The distribution line fault detection system analyzes and judges whether a grounding fault occurs or not according to the voltage signals acquired by the signal acquisition unit, judges whether a circuit breaker performs reclosing operation or not according to different conditions, and uploads fault information to a remote monitoring center through the communication unit. The provided distribution line fault detection system which can judge the working condition of a distribution line according to the fault condition and improve the safety and reliability of the distribution line.
