摘要

Improvements introduced into the subject of the main patent number 8701183/2 for a system for remote measuring of electrical energy consumed by the various users, in which the auxiliary meter concentrator CAM is connected with the main meter concentrator CPM using the low- voltage electricity line, to which end it uses a modem for data transmission via the low-voltage electricity grid, and it is supplied from the said line, to which end it uses a phase selection and fault detector; it also consists of an interface for communication with the pulse generators which has available a first power-supply line for the generators and a second line, by which it receives a pulse of defined shape per consumer unit, which is tapped off to earth by means of a precision resistor and memory units, all being governed by a microprocessor. Applicable in electricity distribution. <IMAGE>
