Abstract

PURPOSE: To hasten the attenuation of the residual voltage with a secondary short resistance inserted into the secondary circuit at the power failure.
CONSTITUTION: When power failure is detected with a power on/off detector 7 in one step, if a switching device is turned on, the next step is activated and in the step 21, the detector 7 memorizes the power failure during the operation simultaneously with the detection of the power failure. At the same time, a timer provided for the power/on or off detector 7 is activated to start counting of time. Simultaneously, in the steps 25 and 26, closed one of a switch 4 or 6 is opened with a sequence device 11 while receiving a gate signal, a thyristor composing a switch circuit 10 to turn on the circuit 10, leading a shorting resistance 9 to be connected to the secondary circuit. In this manner, the residual electromotive force is consumed to lower the residual voltage.
