Electromagnetic Forces in Power Transformers
1010603 Electromagnetic Forces in Power TransformersM.V. PrabhakarT.K. GanguliThe most severe mechanical stressing occurs in a transformer, when it is subjected to a sudden short circuit. Since the currents flowing through the windings at that time are enormous, the forces generated are also enormous. Much work has been done to analyze and calculate these forces. The problem does not yield easy solution due to the transient and dynamic nature of the phenomenon.
