ANSI device numbers - Wikipedia
In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI/IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations.
Many of these devices protect electrical systems and individual system components from dama…Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 3 mins
In North America protective relays are generally referred to by standard device numbers. Letters are sometimes added to specify the application (IEEE Standard C37.2-2008).
