Real Time Transmission Line Fault Monitoring and Analyzing using IoT

Fault monitoring based on Internet of Things technology for Transmission Line is proposed. The proposed diagnostic method monitors online changes in the three phase zero-sequence voltage and current of fixed points on high-voltage transmission lines in real time. The proposed method also equally measures such voltage and current to evaluate the performance of the section and identify short circuits and ground malfunction In fault diagnosis and line maintenance, the Internet of Things enables interflow and interaction among units, such as the detection terminal, signal relay, long-distance control centre and maintenance crew. The proposed detection method has a “self-learning� function; that is, it does not require multiple thresholds on transmission lines with different loads in advance. Performed online in real time, fault diagnosis based on the Internet of Things for electricity supply networks is accurate and convenient.
