Analysis on the Condition of the Electric Energy Metering Device and the Strategy of Inspection

Abstract:

The article points out that it is necessary to apply condition evaluation and condition test to the electric energy metering equipment, based on the actual working condition of electric energy metering equipment. Then, the data of voltage, current, power, frequency, temperature, humidity and so on, are collected by the condition detection equipment of the electric energy metering equipment. Coupling with the errors come from the standard meter and the periodic test on the spot, this article takes the suitable data as parameters, and synthetically evaluates the influence of complicated grid operating environment on accuracy and reliability of energy metering equipment. The criteria which reflect the condition value of the electric energy metering equipment are analyzed to determine the weight of each criterion, to establish the condition evaluation criterion, and to form the condition evaluation system. According to the state evaluation results, different inspection strategies are proposed.
