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.
