Sažetak
When a power transformer is switched to power supply there is a transient inrush
of current in each of the transformer phases. Its peak value mainly depends on the
resistance of the primary winding, the point on the voltage wave at the instant of
switching the transformer on, and the residual magnetic flux of the transformer.
The inrush current is predicted by the time stepping 2D finite-element method
(FEM) coupled with the external electrical circuit. During the switching on
process the electromagnetic forces that appear as a result of inrush currents and
theirs leakage magnetic fields are calculated. An experimental transformer is
built and the measured results are given.
