What is 33KV Oil-immersed Transformer

A 33KV oil-immersed transformer is a type of transformer that is designed to step down high voltage power levels of up to 33 kilovolts (33,000 volts) to a lower voltage that is suitable for use in residential, commercial or industrial applications. These transformers are immersed in a high-quality mineral insulating oil that provides electrical insulation and cooling, ensuring reliable and efficient operation.

The transformer consists of a core made of high-permeability steel laminations that are stacked to minimize magnetic losses. The windings are then wrapped around the core and connected to the high voltage supply and low voltage output. The windings may be made of copper or aluminum and are insulated using high-quality materials to ensure electrical insulation of the windings.

The  33KV oil-immersed transformer comes with a variety of features such as an on-load tap changer, which adjusts the output voltage of the transformer to compensate for variations in the incoming voltage, and a Buchholz relay, which detects the presence of oil gases and faults in the transformer.

Overall, the 33KV oil-immersed transformer is an essential component in the power grid system, providing a reliable and efficient means of stepping down high voltage power to a level that is safe and suitable for use in homes and industries.
