Topic : single phase transformer , Shortcircuit & OpenCircuit , Efficiency of a transformer My question is : Is it logical to say that the Copper loss or Shortcircuit watt meter reading is a FULL LOAD reading @ 3kVA? And if the load is rated for 2kVA do you have to take 2 parts of the 3KVA's watt meter reading for the short circuit test ?

Best ResponseYou've already chosen the best response.0Generally with this test you should be able to determine, copper and core losses, and with other transfomer characteristic you should be able to create a model of input copper losses and inductance, core losses, output copper losses and inductance in which you can determine a load of .85 power factor lagging. Good luck I haven't taken that course in 30 years but the modeling is out there.
