Measurement and Analysis of AC Leakage Current in Preventive Test of 220 kV Insulated Bucket Arm Truck
Insulated bucket arm trucks are important equipment for live working,and their electrical performance directly affects safety of personnel and grid's operation.This paper analyzes abnormal measurement results of AC leakage current on a 220 kV insulated bucket arm truck,which indicates the significant impact of space capacitance current on test re-sults.It proposes a method of using shielded measurement leads to remove interference current,ensuring accuracy and re-liability of the test results,and facilitating safety of personnel and grid's operation.
