Abstract
It has been standard practice to provide stator frame shift on frequency changers that must be paralleled with other units that are already in operation. An installation is described in which it was decided to dispense with frame shifting and obtain no-load phase coincidence by the use of a differential coupling on one unit. Advantages include simplicity and low first cost
