  • Transformer Inrush Current

    2 days ago · A transformer draws inrush current that can exceed saturation current at power up. The Inrush Current affects the magnetic property of the core. This happens even if the transformer has no load with its secondary open. The magnitude of the inrush current depends on the point on the AC wave the transformer is switched on.
