GB/T 17215.304-2017

This standard specifies technical and metrological requirements for static (electronic) electricity meters that measure active energy in alternating current circuits when connected via electronic voltage or current transformers. It is applied in high-voltage or medium-voltage metering installations, such as industrial substations and utility grid connection points, where traditional electromagnetic transformers are replaced by electronic sensors. The standard ensures accuracy, electromagnetic compatibility, and safety for billing and monitoring purposes in these specialized metering contexts.
