Frequently Asked Question

Q1 Which oil is used in the transformer?

It is imperative to note that three types of transformer oil are often used: mineral oil, silicone, and bio-based. Transformer oils based on mineral oil are widely used due to their excellent electrical and cooling characteristics and ability to provide a practical arrangement.

Q2 Why oil is added to the transformer?

The main purposes of transformer oil are to cool and insulate a transformer. As a result, it needs to be highly dielectric, thermally conductive, and chemically stable, and it needs to maintain these characteristics over time at high temperatures.

Q3 What is the power transformer used for?

Power transformers are used to convert high voltage (transmission line) voltage to low voltage (consumer). The transformer is an electrical device that uses electromagnetic induction to transmit energy.
