A (1000+n ) VA 230/2300-V Y-A has been tested to determine its equivalent circuit. The results of the tests are shown below (Given that core lose is 150% of the Cu loss at rated condition) Short-Circuit test (on High voltage side) V sc (20+m) V Isc = (10+m) A Psc = (140+m) W a) Find the equivalent circuit of this transformer per unit system b) Find the transformers efficiency at rated condition and .8 pf lagging
