The paper introduces the time synchronization conception of the IRIG-B format code and its module constructions which include microprocessor, level converter and optically coupled isolator.
The synchronization principle of IRIG-B code is analyzed. When applying IRIG-B code in substation IED, neither communication messages of fieldbus nor multiple pulse signals of GPS are needed.
