The OC and SC test data are given below for a single phase, 5KVA, 200V/400V, 50Hz transformer
| OC test from LV side | 200V | 1.25A | 150w |
| SC test from HV side | 20V | 12.5A | 175w |
Determine the following :-
1) Draw the equivalent circuit of the transformer referred to LV side.
2) At what load or KVA the transformer is to be operated for maximum efficiency?
3) Calculate the value of maximum efficiency.
4) Regulation of the transformer at full load 0.8power factor lagging.
