Description
technical field [0001] The invention relates to an intelligent electric meter constant magnetism detection system and a method thereof. Background technique [0002] The smart meter is the smart terminal of the smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic power consumption measurement function of the traditional electric energy meter, the smart meter also has two-way multiple functions in order to adapt to the use of smart grid and new energy. Intelligent functions such as rate metering function, user terminal control function, two-way data communication function of multiple data transmission modes, and anti-theft function, smart meters represent the development direction of future energy-saving smart grid end-user intelligent terminals. [0003] After the smart meter is manufactured, a series of tests must be carried out according to national standards, one of which is the test of the influence of the magnetic field...
