Abstract
A phase lag adjustment in an electric meter includes a single-turn loop of large cross section encircling substantially the entire flux generated in a voltage stator which interacts which the disk of the electric meter. A variable inductor, in series with the single-turn loop, changes the effective impedance of the single-turn loop thereby adjusting the phase angle of the flux produced by the voltage stator. The variable inductor consists of a small number of turns of copper having a large cross section within a cylindrical shell made of silicon steel. Threaded bushings at each end of the cylindrical shell accept an adjusting bolt from either direction to permit adjustment from either end of the variable inductor. The silicon-steel cylindrical shell is clamped directly over connecting tabs of the cylindrical shell without insulation therebetween. The high resistance of silicon steel can be ignored in parallel with the much lower resistance of the copper turns.
