Phase angle difference between any two Busbar voltages of a big power system varies with the loading and operating condition of the power system. Supplying a common distributed load from these two phase shifted sources needs the application of a controlled phase shifter. Three-phase tapped autotransformer connected in delta with properly controlled variation of input and output tap settings may perform the function of this type of phase shifter. Both on-load and off-load tap changing may be used to control the phase angle for scheduled sharing of a common distribution load between these two phase shifted sources. Independent control of voltage magnitude is also possible through the same phase shifter.
