<p>A transformer based voltage-optimization device 101 is used as a component of an electrical circuit 102 associated with an electrical power supply 103, a load 104 and a bypass switch connection 105. The voltage optimization device comprises a transformer having a control winding, an electrical power input means and a transformer tap. The device also has a control means configured to control the voltage potential across the transformer and equalize the voltage and the associated phase angle of the voltage across the transformer in order to limit the voltage potential across the control winding before disconnecting the transformer from the power supply. To transfer the electrical power supply the bypass switch shorts out the transformer of the voltage-optimization device by connecting its input and output. As the voltage and phase angle across the transformer is equalized, undesirable circulating currents are avoided.</p> |
