摘要
用跨接法、磁耦合法、电耦合法获取局部放电故障信号，依据放电脉冲强度、放电脉冲群频度。
This paper introduces a on line system monitoring the partial discharge trouble of the high voltage equipment in substation. The system acquires the signal of partial discharge trouble by means of bridge connecting, magnetic coupling and electric coupling, and judges the property of the trouble by analysing the discharge strength, frequency of dicharge pulses ensemble, discharge times in negative half period, and distribution status of the discharge pulse.
