摘要

Improvements introduced into the subject of the main patent 8701183/2 for a system for remote measuring of electrical energy consumed by the various users, in which the consumption indicators and the auxiliary meter concentrators CAM are connected with the main meter concentrator CPM using the low-voltage electricity line, to which end the main concentrator 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 is connected with at least one high-quality computer via a telephone line and with portable read-out equipment to which end it uses an infrared interface, and it additionally consists of memory units, all governed by a microprocessor. Applicable in electricity distribution. <IMAGE>
