Design

In transformers, the windings and magnetic circuits are most vital parts. Highly sophisticated design techniques are applied to ensure the required electrical, mechanical and thermal stability against severe fault conditions to withstand multiple times of the rated current which leads to mechanical forces in windings. Windings are built up with sufficient insulations to withstand naturally occurring high voltage surges.

The magnetic circuit layout is made with sophisticated design technique to achieve optimum level of constant losses at the moment of switching on power supply to the transformer.
