A Complete List of ANSI Codes for Relay Protection Functions

Here is a list of ANSI codes for protective relay functions, which are standardized to identify specific protective functions in electrical systems.List of ANSI Codes50 - Instantaneous Overcurrent Relay51 - Time Overcurrent Relay51N - Ground Instantaneous Overcurrent Relay51G - Ground Time Overcurrent Relay59 - Overvoltage Relay27 - Undervoltage Relay81 - Frequency Relay86 - Lockout Relay87 - Differential Relay87G - Generator Differential Relay87T - Transformer Differential Relay47 - Phase Sequence Relay32 - Directional Power Relay40 - Loss of Excitation Relay64 - Ground Fault Relay63 - Pressure Relay94 - Tripping Relay These codes are often followed by suffix letters to provide additional information about the specific application or configuration of the relay. For example, 51G indicates a ground time overcurrent relay, while 59N indicates a neutral overvoltage relay .Additional InformationANSI device numbers are crucial for identifying the functions of protective devices in electrical systems, ensuring that each function is clearly defined and understood. This standardization helps in the design, documentation, and maintenance of electrical protection systems .
