What is the function of HV bushing in transformer?

As the vital link between the high-voltage components inside the transformer tank and the external electrical equipment, high-voltage (HV) bushings are essential to the operation of transformers. The following are the main functions of these bushings:

Electrical Insulation: High-voltage electrical current is kept inside the boundaries of the transformer thanks to the insulation that HV bushings offer for the high-voltage wire inside the transformer. This guarantees the safe transfer of power and stops electrical leaks.

Connection Point: They facilitate the flow of electricity into and out of the transformer by serving as the point of connection between the external circuitry and the internal high voltage winding.

Support and Sealing: HV bushings protect the transformer's internal components from the elements by supporting the internal winding structure and sealing the transformer tank to keep out outside contaminants.

HV bushings are essentially essential parts that make transformers safe and effective to operate, allowing high voltage electricity to be smoothly transmitted while protecting and insulating the internal workings of the transformer. What is the function of HV bushing in transformer?
