Transformer Inrush Current Calculation

Transformer Inrush Current Calculation. Inrush current is a form of over current that occurs during energisation of a transformer and is a large transient current which is caused by part cycle. Since 1994, ametherm has provided the most reliable and effective inrush current limiting solutions available.
