Application Summary AI generated
This standard specifies the digital communication interface for instrument transformers, defining the data formats, transmission protocols, and electrical characteristics for outputting sampled measured values. It is applied in digital substations and smart grid systems where non-conventional instrument transformers (e.g., optical or electronic types) connect to merging units, protection relays, and metering devices via Ethernet-based process buses. The standard ensures interoperability and accurate digital data exchange in high-voltage power systems.
