System and method for magnetizing a transformer in an electrical system prior to energizing the electrical system

An electrical system, comprising:

• a transformer structured to be selectively coupled to an AC source that provides a main AC voltage having a main AC voltage level, the transformer having a number of windings;
• and
• a charging module structured to be selectively coupled to the AC source that provides the main AC voltage to receive the main AC voltage having the main AC voltage level and to generate a magnetizing AC voltage in response to receiving the main AC voltage having the main AC voltage level from the AC source, wherein the charging module is structured to selectively provide the magnetizing AC voltage to the transformer, wherein the magnetizing AC voltage is such that responsive to the magnetizing AC voltage being provided to the transformer one or more of the windings will be magnetized in a manner wherein a voltage of the one or more of the windings is in phase with the main AC voltage provided from the AC source to eliminate or reduce in-rush current into the transformer.
