A Supervisory System for Partial Discharge Monitoring

Continuous measurement of partial discharge plays a vital role in monitoring the status of high voltage equipment in electricity substations. This requires a comprehensive supervisory system to detect, monitor, collect and locate partial discharge activities. Most of the sensors developed so far require a dedicated software and hardware platform to integrate them into a system. A comprehensive supervisory system is proposed and designed that integrates broadband radiometric sensors into a robust wireless network. The network is easy to install and reconfigure. Partial discharge activities are collected by the sensors and transferred to a central database where processed to provide monitoring, visualisation and localisation of the partial discharge sources.
