Most high-voltage bushings for power transformers rated at 110kV and above are OIP Transformer Bushings. They rely on a capacitive core to improve electric field distribution.
Preventive testing for OIP Transformer Bushing involves periodic power-off inspections and tests, primarily including main insulation tests and end-shield tests, along with examinations of other components.
Transformer bushings stand as indispensable elements within power systems. Functioning as current-carrying conduits, they establish a crucial connection between the internal high- and low-voltage leads of a transformer and its external tank. Simultaneousl...
