Abstract :
THE VOLTAGE which must be induced in the secondary winding of a current transformer, in order to overcome the impedance of the circuit, gives rise to a corresponding magnetic flux in the core. It is the ampere turns needed to maintain the flux which constitute the error of the transformer.
