Description

technical field [0001] The invention relates to a data recording and power saving device, in particular to a data recording and power saving device for an electric energy meter, which belongs to the category of measuring instruments. Background technique [0002] The safe and stable operation of the power system and the prerequisite for power market transactions are reliable and accurate power metering. The most commonly used electric energy metering methods in the prior art are inductive, electronic, and multi-functional all-electronic electric energy meters. However, these electric energy meters have single measurement functions, poor accuracy, and unsatisfactory anti-theft functions. For this reason, the anti-stealing electric energy meter with good precision has been developed continuously. For example, the Chinese patent number is Z200720115688.3 (a single-phase anti-theft electric energy meter), and the application number is 200710071547.0 (single-phase anti-theft ele...

Problems solved by technology

At the same time, it can measure and measure anti-stealing electricity when the current is unbalanced. The development of these electric energy meters has greatly improved the work efficiency of the power industry, making it impossible for some criminals to achieve the purpose of stealing electricity.

But its cost is high, energy consumption is also high, operation is inconvenient, and the data cannot be copied and received by the handheld in the state of power failure
