Device numbers are used to identify the functions of devices shown on a schematic diagram. Function descriptions are given in the standard.See all results for this questionWhat is a protective device number?Protective Device Numbers Protective relays are commonly referred to by standard device numbers. For example, a time overcurrent relay is designated a 51 device, while an instantaneous overcurrent is a 50 device. Multifunction relays have combinations of device numbers.See all results for this question
ANSI/IEEE Device Numbers Protective relays are commonly referred to by standard device numbers. For example, a time overcurrent relay is designated a 51 device, while an instantaneous overcurrent is a 50 device. Multifunction relays have combinations of device numbers. A 27/59 device, for example, is a combination under/over voltage relay.See all results for this questionWhat function does an ANSI 69 device provide?In the design of electrical power systems, the ANSI standard device numbers (ANSI /IEEE Standard C37. 2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations) identifies the features of a protective device such as a relay or circuit breaker.What are the IEEE/ANSI Device Numbers Used in Power In power system, the protection and control of equipment is represented by ANSI device numbers, with corresponding suffix letters when necessary, in relation to the functions they perform.
