If i have three single phase transformers of different capacities, say two 50 kVa transformers and one 75 kVA, connceted in a star-star configuration, and i also have the line and phase voltages and currents on the secondary side of the bank taken by a clip-amp meter or some other device, how do i determine the total load the bank is supplying?
For example i may have measurements on the secondary side of the bank as follows :
Line Voltage (Red-Blue phases) = 228 V
Line Voltage (Red-White phases) = 230 V
Line Voltage (White-Blue phases) = 227 V
Line/Phase Current I (Red Phase) = 15 A
Line/Phase Current I (Blue Phase) = 14 A
Line/Phase Current I (White Phase) = 15 A
How do i determine if the bank is overloaded from these readings?
Thnx
