Abstract

The core of the detection system is if the partial discharge signal is effective, clear and reasonable during the process of on-line monitoring of partial discharge in cable terminal. The safe operation of cables in power system can be guaranteed through the effective detection method of partial discharge source to predict failure risk of the electrical insulation equipment. The use of ultrasonic method can effectively reduce electromagnetic interference and be easy to achieve on-line monitoring. The partial discharge location can be orientated through changing the sensor position and using Levenberg-Marquardt algorithm. The relationship between magnitude of partial discharge and amplitude of ultrasonic signal, the characteristics and the propagation law of the ultrasonic signal were analyzed in the experiment
