According to the “traceability” technical methods and feasibility analysis of digital electrical power meter, the concept of computational analog standard meter and a related “traceability” method were proposed to make the “traceability” method keep in line with that of the original analog electrical power meters. It is helpful to maintain the stability of standard value traceability and transfer system for electrical power meter. The breakthrough in the “traceability” concept for digital electrical power meter simplified digital electrical power metering, also solved the controversial issues appeared in digital electrical power meter traceability methods.
