Research on Testing Technology of Functional Reliability of Electric Energy Meter Basing on Weak Spot Detection

As the most powerful and intelligent equipment in the field of energy consumption on the customer's side, electric energy meters has been applied far more exceeded the bound of traditional metering function, and assume the role of energy information processing center day by day. Therefore, engineering practice is raising its demand on electric meter's functional reliability. However, there is still no proven and reliable method and technology for rapid reliability testing. Aiming at solving this problem, this paper proposes a testing technology of functional reliability of electric energy meter basing on weak spot detection, which can significantly decrease testing period, improve the pertinence of testing and provide guidance and support for the installation and operation of electric energy meters.
