The definition and application of function numbers and acronyms for devices and functions used in electrical substations and generating plants and in installations of power utilization and conversion apparatus are covered. The purpose and use of the numbers and acronyms is discussed, and 95 numbers and 17 acronyms are assigned. Function numbers or function acronyms for arc fault detection, high impedance fault detection, human machine interface, communications devices, digital fault and sequence of event recorders, power quality recorders, substation time sources and synchrophasor devices are among those that have been added. The use of prefixes and suffixes to provide a more specific definition of a function is defined. Device contact designations are also covered.

C37.2-2022
IEEE Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations
The definition and application of function numbers and acronyms for devices and functions used in electrical substations and generating plants and in installations of power utilization and conversion apparatus are covered. The purpose and use of the numbers and acronyms are discussed, and 95 numbers and 22 acronyms are assigned. Function numbers or function acronyms now exist for arc flash detection, clock or timing source, dynamic disturbance recorder, digital fault recorder, disturbance monitoring equipment, environmental data, fault data concentrator, high impedance fault detector, human machine interface, historian, scheme logic, substation metering, phasor data concentrator, phasor measurement unit, power quality monitor, remedial action scheme, remote input/output device, remote terminal unit/data concentrator, sequence of events recorder, and trip circuit monitor. The use of prefixes and suffixes to provide a more specific definition of a function is defined. Device contact designations are also covered.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C37.2-1987
IEEE Standard Electrical Power System Device Function Numbers
Superseded. This standard applies to the definition and application of function numbers for devices used in electrical substations and generating plants and in installations of power utilization and conversion apparatus.
C37.2-1991
IEEE Standard Electrical Power System Device Function Numbers
Superseded. The definition and application of function numbers for devices used in electrical substations and generating plants and in installations of power utilization and conversion apparatus are covered. The purpose of the numbers is discussed, and 94 numbers are assigned. The use of prefixes and suffixes to provide a more specific definition of the function is considered. Device contact designation is also covered.
C37.2-1996
IEEE Standard Electrical Power System Device Function Numbers and Contact Designations
The definition and application of function numbers for devices used in electrical substations and generating plants and in installations of power utilization and conversion apparatus are covered. The purpose of the numbers is discussed, and 94 numbers are assigned. The use of prefixes and suffixes to provide a more specific definition of the function is considered. Device contact designation is also covered.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
