Test Analysis of an Oil-immersed Current Transformer Failure
It introduces the maintenance process of a 110 kV oil-immersed current transformer after failure.Through oil chromatography and dielectric loss test,it was found that there was an in-ternal fault.The transformer was disassembled and inspected after the power off,it shows the inter-nal primary winding insulation paper was partially aged with heating discharge and wrapping defects.It also can provide reference for operation and maintenance for the similar equipment.
