to calculate kva rating of single phase transformer: kva rating= Q =Vp * Ip * 10^-3where,Vp= terminal voltage of primary windingIp= current of primary windingso,Q = V * I *10^-3 =2.22 * f * phi *Kw...
You can't determine the output voltage of a transformer by knowing kva. Transformers will be marked as to input and output voltages. Some will have multiple input and output voltages. The output...
