RELAY MODEL NUMBERING GUIDE SCHNEIDER SIEMENS

Relay Protection Terminal Numbering Rules

In and, ANSI Device Numbers can be used to identify equipment and devices in a system such as,, or. Many of these devices protect electrical systems and individual system components from damage whe. These numbers are based on a system that is adopted by a standard for automatic switchgear by Institute of Electrical and Electronics Engineers (IEEE), and incorporated in American Standard C37. This system is used with diagrams that are found in instruction books and in specifications.

Complete Guide to Relay Protection Indicators

The objective of relay protection is to quickly isolate a faulty section from both ends so that the rest of the system can function satisfactorily.

What is the model number of the relay protection device

In and, ANSI Device Numbers can be used to identify equipment and devices in a system such as,, or. Many of these devices protect electrical systems and individual system components from damage whe. For example, a time overcurrent relay is designated a 51 device, while an instantaneous overcurrent is a 50 device. The International Electrotechnical Commission (IEC) standards 617 and 60617 also provide different symbols and terminology for most of the device numbers that are defined by C37.
