局部放电在线监测电流传感器的等效电路及其参数计算

Equivalent Circuit and Parameter Calculation of Current Sensor of On-line Monitor of Partial Discharge

局部放电在线监测是保证电力设备正常工作的重要手段。从变压器理论出发 ,提出了局放脉冲电流传感器等效电路及其参数计算方法 。

On line monitor of partial discharge is an important measure to ensure that the electrical power equipment works well Based on the theory of transformer, the paper proposes the equivalent circuit and parameter calculation of PD pulses of current sensor The developed method is used successfully for sensor design of factual PD on line monitor
