but no load current is so small.. as we know pf is inversely proportional to current then it should have been high when no load current is small right??

 

Dear ;

 

As we know all, the ” no-load current ” of a transformer is the ” magnetizing current “, that means the current of the transformer’s impedance ” Reactance + Resistance “, and as the biggest one of those is the reactance, so the PF of no-load current is small or too small.
