Abstract
This paper introduces a kind of device which uses high frequency pulse current method to detect cable partial dis-charge.Using high-speed broadband sampling and signal separation and classification technology,this device is able to im-prove detection rate of partial discharge pulse in strong background noise and detecting precision and reliability.In addition, the device is feasible to provide reliable detecting schemes for detecting and positioning for straight joint and insulated joint.On the basis of testing in test room and field application,it proves good effectiveness of this device.关键词
