The process of determining the transient surge of current that flows into a transformer’s primary winding when it’s initially energized is crucial for power system design and operation. This surge, often several times larger than the transformer’s normal operating current, arises due to the magnetic flux within the core needing to establish itself. Factors like the residual magnetism in the core, the instant of switching on the voltage waveform, and the impedance of the power system all influence the magnitude of this initial current spike.
