Analysis on The Cause of Abnormal Capacitance of Valve Side Bushing of a Converter Transformer
In this paper the author introduces a case of capacitance out of tolerance of valve side bushing of ±800kV UHV converter transformer before installation, expounds the testing methods of schering bridge, analyzes the measurement conditions and methods of A type valve side bushing before installation, points out the protection tube to dismantle or not has a great influence on the capacitance measurements, it is major causes of abnormal test results.
