Windings and Insulation
1010603 Windings and InsulationM.V. PrabhakarS.K. GuptaWindings form the electrical circuit of a transformer. Their construction should ensure safety under normal and faulty conditions. The windings must be electrically and mechanically strong to withstand both over-voltages under transient surges, and mechanical stress during short circuit, and should not attain temperatures beyond the limit under rated and over-load conditions. For core-type transformers, the windings are cylindrical, and are arranged concentrically. Circular coils offer the greatest resistance to the radial component of electromagnetic forces, since this is the shape which any coil will tend …
