Abstract

1. Electronic electricity meter having a multiplier (1, 2), operating according to the timedivision method, for first and second input quantities (U, I), the first input quantity (U) being supplied to a modulator (1), representing a component part of the multiplier (1, 2), and having a quantizer (3), subsequently connected to the multiplier (1, 2), the quantizer (3) operating according to the charge compensation method and being constructed with an integrator (17, 18) and a subsequently connected first comparator (26), characterized in that the multiplier (1, 2) and the quantizer (3) have the following features : a) during each first time phase of a clock generator (8) a first capacitor (23) is connected to the input of the integrator (17, 18), b) during each second time phase of the clock generator (8) the first capacitor (23) is charged with a charge proportional to the second input quantity (I), c) the polarity with which the first capacitor (23) is placed at the input of the integrator (17, 18) is determined by the output signal of the modulator (1), constructed according to the delta-sigma method and controlled by the clock generator (8), d) a second capacitor (25) is charged with a reference charge, while the output of the quantizer (3) is at "0", and is placed at the input of the integrator (17, 18), as long as the output of the quantizer (3) is at "1", e) a flip-flop (27), controlled by the clock generator (8), is subsequently connected to the first comparator (26), the output of the flip-flop (27) representing the output of the quantizer (3).
