Abstract

716,721. Supply meters. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 2, 1952, [Oct. 3, 1951.] No. 23079/51. Class 37. An induction type electricity meter has a disc or rotor provided with a series of anti-creep holes of such number and size as to provide a braking torque of the magnitude required to prevent excess running of the disc at above normal (e.g. +10 per cent) system voltages.
