1 4570Hello friends., my question is related to testing of current transformer... A Ct having knee point voltage of 750 volts., and I have two step up transformer's of rating 230 v to 440 volts., can I obtain the value of 750 volts by using the two transformer's.... If yes then how could I connect the transformer's to obtain knee point voltage?? thank you in advance
