Abstract :

Short circuit electromagnetic forces are considered as important factor from design point of view of transformer and should be taken care of while designing a transformer as it has very serious damaging effect to the transformer. Short circuit forces are more dominant in case of large power transformers. The work has been carried out on a power distribution transformer. The procedure for the analysis of power distribution transformer can be used to calculate the short circuit electromagnetic forces of large power transformer also. Therefore, a 630kVA, 11/.433kV power distribution transformer has been modelled for analysing the short circuit electromagnetic forces. Windings are modelled in twenty-three sections and short circuit force of each and every section of the winding is calculated using Finite Element Method of analysis. Electromagnetic forces are calculated for single helical and double helical windings of transformer.
