Waveform diagram illustrating transformer inrush current causes, peak values, and protection methods.

Transformer inrush current is one of the most common causes of unexpected circuit breaker trips during transformer energization. When a transformer is switched on, its initial magnetizing current can rise far above its normal operating current, even when no load is connected to the secondary winding. For industrial power systems, understanding transformer inrush current is […]
