I think the "varnish" you're referring to is the insulation on the windings and the iron core. The purpose of insulating the windings is to keep the different phases/poles/coils insulated from each other, and to keep the coils insulated from the iron core. If there were no insulation, the windings would short out against each other, or ground out against the core.Originally posted by Maricarl@Jul 6 2005, 09:45 PM
Why is varnish applied in transformer?
What is the effect if transformer is not applied?
What is the composition of varnish?
