Description:

This white paper discusses the latest revisions of ANSI C12.1-2015 and ANSI C12.20 – 2015, particularly as they apply to type testing of solid state energy meters, and which provide several important clarifications that influence new meter designs and type testing. These revisions underscore the benefits of higher accuracy class 0.1 metering: increased meter robustness, and increased metrological performance with highly distorted signals. They also make ANSI revenue meters more suitable for use on modern electricity distribution networks, yielding meter designs that match modern advancements in metrology, and growing customer expectations of more robust, more accurate measurements in billing applications. Only requirements applicable to energy meters are discussed.
