For the sake of identifying the fault of electric power cables easily and practically
this paper presents a new method to measure capacitive current of single-phase/three-phase power cable with two-terminal earthed or multi-points earthed
on the basis of comprehensive analysis of common used on-line insulation monitoring approaches of power cables. Corresponding criteria of insulation condition are given and prototype of measurement device is also designed and realized. Furthermore
in order to verify the effectiveness of the method and criteria
