Abstract
PURPOSE: To reduce voltage regulations by inserting a tap transformer between a short circuit generator and a testing transformer.
CONSTITUTION: A tap transformer 2 is inserted between a short circuit generator 1 and a testing transformer 3 and the applied voltage to the short circuit generator 1 is regulated by making the generating voltage of the short circuit generator 1 always constant (maximum generating voltage) and changing the taps of the tap transformer 2. Then, the internal impedances of the short circuit generator 1 which become the governing factors of the magnitudes of the voltage regulations owing to the presence or not leakage current become minimum through maintenance of the generating voltage at maximum, thus even if the test voltage is changed in various ways, the voltage regulations are kept at ±5% and the need for using the short circuit generator 1 of a large capacity is eliminated.
