Guide HANDBOOK
Relays with suitable characteristic on R-X diagram have to be carefully chosen to protect long and heavily loaded lines, and this becomes easily possible with microprocessor based numerical relays.
Guide Table of ANSI IEEE Standard Device Numbers
This table details ANSI IEEE Standard Device Numbers as used for protective relaying in North America. Suffixes for numbers are also suggested.
Guide Protection Relays Numbering (ANSI) | PDF
It includes 99 device functions numbered 1 through 99 with descriptions such as master element, time-delay starting or closing relay, AC time overcurrent relay, AC circuit breaker, exciter or DC generator
Guide ANSI codes and IEC Relay Symbols – Electrical Engineering
To assist the Protection Engineer in converting from one system to the other, a select list of ANSI device numbers and their IEC equivalents are given in the following figure.
Guide ANSI/IEEE Function Number Codes
Protective relay functions are typically represented in single-line electrical diagrams as circles, with the ANSI/IEEE number code specifying each function. This is analogous to ISA-standard loop diagrams
Guide Understanding the ANSI/IEEE Device Numbering System
For protection engineers, a thorough understanding of this numbering system is essential for effective communication, proper relay configuration, and coordinated protection design.
