engineering recuitment GATE EE 2023-24 Test Series Electrical Machines Transformer Transformer on Load
The open circuit test performed on HV side of a single phase transformer gives the following data.
\({V_1} = 660V,{V_2} = 220 V\)
Current = 0.6 A, Power = 45 W
Now, when transformer is running on load, what will be the primary current when the secondary current is 270 A at 0.85 pf lagging?
