Digital Protection Relays

Mr. George E. Alexander, Schweitzer Engineering Laboratories

625 Clark Ave., Suite 655, King of Prussia, PA 19406

 

 

Abstract:

This discussion will focus on microprocessor based distance protection. For transmission and sub-transmission lines, and current differential protection For transformers and buses. The ability of the microprocessor relay to integrated a variety of protection functions into one relay will be demonstrated. The talk will also address the non-protection features that are typically included in a microprocessor relay such as metering, monitoring, event reporting, self-testing, and communications. The flexibility provided by the programmability of the microprocessor relay will be explored. If time permits, the discussion will include substation communications and integration capability of the relays.
