Abstract :
Measurement of partial discharge by electromagnetic method is widely used in high voltage testing. This paper deals with the three-axis loop antenna to detect the electromagnetic signal caused by partial discharge. The principle of the newly developed three-axis antenna and some experimental results are shown in this paper. Test result shows that the antenna has high sensitivity and space resolution for the directivity.
