Common Fault Types And Diagnosis Methods Of Transformer Epoxy Resin Bushing

There is also the porcelain epoxy bushing wrapped around the outside, and the transformer oil filled inside also plays an insulating role. The remaining epoxy resin bushing parts include some accessories with a fixing function. Due to the principle of capacitor voltage division, the decline in the insulation performance of a certain part in epoxy resin cast bushing will cause the capacitance to change, thereby causing epoxy bushing manufacturer to discharge or creepage, etc., affecting the insulation performance of the entire epoxy bushing for transformer.
