Abstract

This paper summarized global research status of test equipment of UHV transformer’s AC withstand voltage and partial discharge tests.Referred to the 1 000 kV-transformer testing data from UHV test-base of Wuhan high voltage research institute

a testing method and a circuit schematic diagram are both proposed

which are applied in ACWV test and PD test on UHV equipments.Design methods of frequency conversion power supply and high voltage reactor in the equipment are discussed.This paper has proved the rationality of the testing appliance by analyzing the data from ACWV test and PD test on 750 kV EHV equipments

and the data demonstrates that the testing equipment has high stability

good security

strong practicability and good potential in application.
