Hello 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

Connect 230 V sides of trs in parallel with
dimmer-stat.Connect secondaries in series . Connections
should be done in such a way that the secondary voltages add
to each other.This can be ensured by measuring voltage .
