Abstract
593,010. Supply meters. ENGLISH ELECTRIC CO., Ltd., and TAGG, G. F. June 11, 1945, No. 14731. [Class 37] In an induction watt hour meter a power factor compensating coil wound around the pole of the series magnet is closed by an adjustable resistance supported within a moulding 2 and formed.of tapered strips 10, 11 of high resistance material such as michrome dimensioned to give a change of circuit resistance such that the rate of change of meter registration with movement of a bridging clamp 4, 4a is nearly uniform.
