摘　　要：分析了从电网二次侧测量配电网电容电流的方法,根据情况可分别从电网的PT开口三角端或消弧线圈的二次绕组注入变频恒流信号,从而计算出配电网对地电容电流。Measurement of capacitive current in power distribution network by injecting current of various frequencies are introduced. The current is injected into the opening deleta windings of the network PT, or into the secondary winding of the Petersen coil. By using the formulae given in this paper, the capacitive current can be calculated.
