Description

technical field [0001] The invention belongs to the technical field of energy efficiency measurement, and relates to an energy efficiency measurement device and method, in particular to an electric energy measurement device and method. Background technique [0002] As a kind of energy, electricity occupies an extremely important and irreplaceable position in the production of national economy. At present, there are two development trends in electric energy measurement: 1. In my country, due to the prominent contradiction between power supply and demand, the country advocates energy conservation, especially electric energy conservation; at the same time, in order to use electric energy rationally, time-of-use electricity prices are actively implemented in various places; 2. Electric energy Metering instruments will no longer be simple electric energy metering, but will integrate metering, electric energy management, and intelligent meter reading functions, and will develop in ...
