What is the consequence of not managing magnetizing current properly during energization?

Managing magnetizing current during energization is crucial for the stable operation of electrical systems. When magnetizing current is not properly managed, it can lead to a situation where the inrush current significantly exceeds the normal operating levels during transformer energization. This high inrush can cause voltage dips in the power system which, in turn, may affect downstream equipment.

Consequently, these voltage dips can trigger protective devices or relays, resulting in service interruptions. Therefore, it's essential to carefully manage the magnetizing current to maintain system stability and avoid disruptions in electrical service. Proper management ensures that the equipment is energized smoothly and does not lead to unexpected outages.
