The Research and Application of Single-phase Prevent Electricity from Theft Watt-hour Meter’s Principle

In order to research how to improve the anti-steal ability of single-phase Watt-hour meter, the existing means of theft were analyzed. The structure and manufacturing process of the energy meter were designed and improved from the aspects such as energy meter seal airtight and security features of anti-prizing, to optimize the working module and counter. That made it difficult for Badmen to steal power and improve the meter’s anti-steal ability. This paper analyzed the working conditions and the benefit of the meter. The results show that the meter reduces the consumption and prevents from the theft.
