Abstract

The application status of the internal UHF sensor for monitoring partial discharge in power transformers is introduced

and then the feasibility of using external UHF sensor for detecting partial discharge activities is analyzed.A measurement system based on UHF method for studying PD is designed.Experimental results show that the UHF signals can diffraction through the transformer’s joint.Through detecting the diffraction UHF signals outside the transformer

it can be a new approach to detecting PD of transformers.
