Abstract

CURRENT MEASURING TRANSFORMER TO ACHIEVE A PROPORTIONAL VOLTAGE TO THE CURRENT TO MEASURE, with a closed iron core crossed by the current to be measured and with a secondary winding that is short-circuited directly without load impedance and the iron core also carries another winding, in whose terminals the voltage proportional to the current to be measured appears.
