Dielectric Loss and Capacitance Test Method on 220kV CVT without Dismantling HV Lead |
| |
| Abstract: | In order to reduce the equipment damage caused by dismantling the high voltage down-lead and improve the examining and repairing efficiency,according to the construction feature of 220 kV integral type CVT,this paper presents a method for testing dielectric loss and capacitance without dismantling high voltage(HV) lead,analyses the testing principle and error,and proposes a data-processing method.The testing and data-processing method is verified by comparing the test data with dismantling HV lead. |
