Abstract:

The forces exerted due to the transient currents in a power transformer can result in deformity of core and winding. These transient currents are the excessive current arising in the transformer at the time of short-circuit fault. This study aims in examining the axial and radial force generated in the transformer's high voltage winding and the deformations associated with it when a double line short-circuit fault occurs. The analysis has been done for a three phase 11/66 kV power transformer of 40 MVA. Finite element method is employed using COMSOL Multiphysics. The electromagnetic force study is significant in determining various design parameters of the power transformer so as to protect it from the harmful effects taking place due to the transience in currents.
