A Survey on GPS clock module based different timing outputs for time synchronization system
Keywords:
GPS, NTP, NMEA, IRIGAbstract
Presently days, Time synchronization is basic to current electrical power systems.SCADA system, slave
display device, data loggers, protective relay, sequence of event recording (SER), digital fault recorder,remote terminal
units (RTUs) and other intelligent Electronics Devices (IDEs) all are the different types of microprocessor based power
systems instrumentswhich require precise timing for their proper working.IN this survey low cost GPS (Global
positioning system) clock based different timing outputs like NMEA(National marineelectronics associations), Inter
range instrumentation group – B(I.R.I.G-B), Network time protocol (N.T.P) for time synchronized system.
