Principle Of Electronic Energy Meter
An electric energy meter is a meter used to measure electric energy. The earliest electric meter should be an induction (mechanical) electric energy meter at the end of the 19th century. The electronic energy meter appeared later.
The electronic energy meter is mainly composed of voltage and current sampling and dedicated energy meter chips (such as BL0932B, ADE7755, etc.). Its task is to complete the accumulation and storage of each user's power consumption, and at the same time convert the power into corresponding pulses to be output or sent to the single-chip microcomputer for processing. The household electric energy metering unit is centrally installed on a printed circuit board, and its area is smaller than a paper cigarette box, one for each household, and each household is individually metered without affecting each other.
The structure of electronic energy meter and single phase meter is composed of voltage coil, current coil, turntable, rotating shaft, brake magnet, gear, counter and so on. It's just that the function deletion will be slightly different. yhddb.com
