Abstract

A system (10) for power and / or energy consumption metering on an AC power line network (1) of a plurality of channels (C 1 , C 2 ,...,C n ) supply the corresponding electrical load (L 1 , L 2 ,...,L n ), said system comprising: a central unit (11) connected to said AC power line network (1), said central unit (11) comprising a single central voltmeter (110) supplied by a power supply unit (112); clamp unit (12), which is distributed in each channel to be measured (C 1 , C 2 ,...,C n ), each clamp unit (12) is clamped around the existing cable and includes a current transformer (120) to measure the current value. Said plurality of clamp units (12) are connected to said central unit (11) for data transmission and synchronization, and for power supply by means of said power supply unit (112).

Description

technical field [0001] The present invention relates to the field of energy metering, and more particularly to the field of electrical power and energy metering. Background technique [0002] Power and / or energy metering on AC main loads can be used for several purposes ranging from billing to customer-awareness of energy consumption. In any home, office or industry, energy is supplied to run lighting, tools, personal computers (PCs), machinery and any other kind of equipment that requires energy. [0003] To better harness the energy, the concept of customer awareness is now gaining momentum. [0004] There are already several solutions on the market enabling the user to take a sub-measure (measurement after the energy provider has been billed with the main counter) on selected loads. Among them, the smart plug is an easy way to measure a single load. Such meters do not have to be subject to any special regulations (other than eg the standard defaults of the European Com...
