Fig. 4.—Method of obtaining Primary Current Locus by thePrinciple of Reciprocal CLOSED CIRCUIT OPEN CIRCUIT and is in the direction of OA, and the secondary resistance isvaried. Admittance and Impedance Loci. 305 The electromotive force has the position OJ on open circuitand ON on short circuit. OH is the power electromotiveforce on open circuit, and includes the effects of primaryresistance and the losses due to hysteresis and eddy currents;HJ is the electromotive force to overcome the primary self-induction. These are in the direction of the primary current,and at right angles to it, respectively. A line from J to K,at right angles to the secondary current, would show thereaction of the secondary upon the primary. It is to benoted that the line NH represents the effects due to magneticleakage. It is desired to find the locus for the primary cur-rent when the primary electromotive force has a constantvalue, and is drawn in the direction OA. The angle of lag 0Ubetween the primary electromotive force and current on opencircuit, is JOH. Accordingly, with a constant
