1. A 200 KVA 3300/240volts, 50Hz single phase transformer has 80 turns on the secondary winding. Assuming an ideal transformer. Calculate (1) the primary and secondary current on full load (2) the maximum value of flux (3) the number of primary turns. 2. A transformer has 200 turns in the primary, 50 turns in the secondary, and 120 volts applied to the primary (Ep). What is the voltage across the secondary (Es) 3. Find the efficiencies of a 150KVA transformer at 75% of full load at unity power factor and 100% of full load at power factor of 0.8 lag. If full load copper losses are 1.6 KW and the core lossés are 1.4 KW.
