Abstract
Phase angle regulator for high voltage power distribution systems. An electrical transformer having inductively coupled series and regulating windings is provided with the series windings connected between a source of electrical power and an electrical load circuit and the regulating winding connected to an excitation transformer which, when excited, causes a voltage to be induced in the series windings which is in quadrature with the line conductor voltages. Auxiliary windings, one of which is arranged in a partial interconnected star configuration with each regulating winding, are connected to a regulating winding in a different phase of the series transformer to cause the voltage induced in the respective series winding to be phase shifted to a predetermined electrical angle with respect to the line voltage which minimizes the variation between the load and source voltages over the range of phase shifts provided by the phase angle regulator.
