Abstract:

In order to solve both the testing and the “tracing” problems of digital watt-hour meter, the concepts and equipment of “Analog Merging Unit”, “Computational Analog Reference Meter”, “Digital Synthetic Analog Power Source” was introduced, and three kinds of thorough testing methods, i.e., “Standard Source Comparison Method”, “Reference Meter Comparison Method”, and “Comprehensive Comparison Method”,as well as the corresponding complete standard transfer “tracing” systems was provided. By doing so, the testing and the “tracing” of digital watt-hour meter can be reasonably included into the standard transfer “tracing” system of the traditional watt-hour meter, so that digital electrical energy metering can adopt the analog metering system completely. Then, technical problems of the testing and the “tracing” of digital watt-hour meter can be solved concisely, scientifically, and economically. The unity of digital and analogelectricalenergy metering systems, inherits the uninterrupted continuity, stability, and seriousness of the standard transfer “tracing” system of electrical energy metering, and has certain logic, rationality and conscientiousness, and also reduces the risk of digital power energy metering system. Getting rid of the “digital” part during digital electrical energy metering process is an innovation and development for electrical energy metering technology.
