05-ME-38APPARATUS AND METHOD OF PHASE SHIFT COMPENSATION OFAN ACTIVE TERMINATED CURRENT TRANSFORMERABSTRACT OF THE DISCLOSUREApparatus and method of compensating for a shiftin the phase of the current applied to a currenttransformer terminated in a low impedance operationalamplifier. The operational amplifier phase response isaltered to minimize the phase angle between thetransformer current and the amplifier output voltage tothus provide an output voltage directly proportionalto the transformer current.
