Answer Posted / akash pandey
if a transformer is of X VA then it means that this is the
burden of secondary side and also we knoe that this output
power is limited by the losses namely the core loss
depending on V and ohmic losses depending on I hence the
rating is given in VA. Consider a case where the power
factor of the load is ZERO hence the power delivered will be
zero but losses will still be there ...hence the output
varying with the condition ...but whats constant is VA.
