The nameplate on a 70 kva transformer shows a primary voltage of 480 volts and a secondary voltage of 115 volts. we wish to determine the approximate number of turns on the primary and secondary windings. toward this end, three turns of wire are would around the external winding, and a voltmeter is connected across this 3-turn coil. a voltage of 50 volts is applied to the 115 volt winding and the voltage across the 3-turn winding is found to be 0.77 volts. how many turns are there on the 480 v and 115 volt windings (approximately)?
