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.
