Through the high and low voltage insulating bushing, the transformer conducts its high and low voltage windings from the oil tank to the outside. The transformer winding is insulated from the earth (shell and iron core) by the high and low voltage insulation bushing, which also serves ...
What is the purpose of the transformers?TransformerTransformer is a static electrical device that transfers energy from one circuit to another by means of electromagnetic induction. This works by varying the current in one coil to produce varying magnetic flux in the transformer's core. This ...
What is the difference between a step-up and a step-down transformer? Give examples where each would be used. What is the difference between step up and step down transformer? What is the working principle of the transformer and which type of current is applied?
Introduction: Transformer internal cited the high voltage and low voltage leads to a tank outside the insulating sleeve, not only as a lead-to-ground insulation, and bears a fixed lead, transformer bushing is one of the transformer current-carryi...

droplets of moisture accelerate partial discharge activity in the bushing assembly. Since air is a significant component of the insulation system inmodern switchgear, moisture carried in air alters its dielectric properties. Partial discharge is more likely because of the air’s lower breakdown strength...
Since the bushing is usually protected by an air gap or arrester whose insulation under surge is lower than its own, flashover will occur across the bushing and the grounded tank. The weakest insulation should be weaker by a sufficient margin than that of the principal equipment it is ...
