Abstract
An auxiliary generator supplies a sinusoidal voltage of fixed amplitude adjusted in phase to the mains supply voltage. A comparator, followed by a threshold circuit and a bistable switch, enables a static contactor to be opened almost instantaneously when the difference between the voltages of the mains supply and of the generator exceeds a certain preset value. Power is then supplied by an auxiliary back-up power supply.
