초록 ▼

A process for measuring electricity consumption, especially suitable for small consumers, comprises the steps of continuously measuring consumer current, integrating the current with time to obtain a value (A.h) relating to consumption; adjusting the integration in function of the voltage of the network to obtain an adjusted value (A.sub.v.h) proportional to a preestablished unit of electricity consumption; and computing the number of preestablished units obtained to provide a value proportional to chargeable electricity consumption. The adjustment to the integration is carried out in accordance with four bands of network voltage, in the form of a nominal band on either side of the nominal network voltage, an overvoltage band, an extended voltage band below the nominal band, and an undervoltage band. An electricity meter for performing the process includes a current transformer (TC) having a primary which is the consumer load line (15) and a secondary which generates a current representative of the current in the load line, a circuit connected to the secondary to integrate the value of such current with time, a detector for detecting when the integration circuit reaches a preestablished chargeable unit value of consumption of electricity, and a counter associated with the detector to sum the detected units of consumption.

[ We claim:] [1.] Measuring process for measuring chargeable electrical consumption from an electrical network, characterised by comprising the steps of:a) carrying out a permanent measurement of the current of the consumer;b) integrating the value of the measured current with respect to time until a value. (A.h) is obtained relative to the electrical consumption by the consumer;c) adjusting the integration step b) in function of the electrical voltage of the network until an adjusted value (A.sub.v.h) is obtained that is proportional to a preestablished unit of electrical consumption; andd) computing the number of preestablished units obtained so as to obtain a value proportional to the electrical consumption chargeable up to any given moment.
