Validation of model for medium voltage distribution transformer under inrush current conditions

Pole mounted transformers are subject to inrush currents, that occur during start-up of the transformer. The inrush currents may cause unwanted forces on the windings. Testing was done at a Transformer Testing Facility to develop a model to understand the inrush currents. The model matched measured...

Summary:Pole mounted transformers are subject to inrush currents, that occur during start-up of the transformer. The inrush currents may cause unwanted forces on the windings. Testing was done at a Transformer Testing Facility to develop a model to understand the inrush currents. The model matched measured results closely.
