Abstract
Voltage regulation of power transformers by the use of a separate, removable, detachably coupled device external to the main transformer that can be attached to a main transformer unit when voltage regulation is desired. The device is connected to the three neutrals of the main transformer and can comprise: (a) a bank of three capacitors connected in wye, (b) a bank of three medium voltage (MV) or low voltage (XV) transformers, (c) one three-phase low voltage or medium voltage transformer, or (d) a combination of a XV/MV transformer and a capacitor bank.
Claims11
A transformer system for use in an electric power system, comprising:
- a power transformer;
- and
- a voltage regulation device detachably coupled to the transformer and external to the transformer, the voltage regulation device regulating the magnitude of the voltage of the transformer.
