This paper is intended to supplement to the existing 1999 relay trip circuit design paper to address the use microprocessor relays. The report will exclude ac voltage and current inputs, GOOSE, internals of relays, and IRIG and communication issues. It will include signaling between protective elements such as relays, breakers, etc. primarily as it applies to trip and control circuits.
