Time Synchronization in Electrical Systems
Time synchronization for substations with integrated protection- and system control functions, as well as data collection require a target architecture that distributes synchronized time in several ways.
TIME SYNCHRONISATION USING ABB RELAYS
In cases where time synchronization is not part of the protocol, the ABB has included innovative and industry standard methods of obtaining the time synchronized data using standard data access
Time in IEC 61850 based substation protection and control systems
Different time sources and the use of PTP ensure that all the data used within the system will maintain continuously high-accuracy time synchronization to improve the reliability and security of the electric
Document tag

Power-Utility Time Synchronization (IEC 61850)
In this video it is shown how non-PTP capable protection relays can be integrated into IEEE 1588 time synchronization infrastructures using the PTP
How Electrical Relays Work
A relay is an electromagnetic switch that opens and closes circuits electromechanically or electronically. A relatively small electric current that can turn on or off a much larger electric current operates a relay.
Understanding the Impacts of Time Synchronization and Network
IEC 61850-5 standard defines the time requirements for latency in protection systems as the transfer time . Table IV lists the transfer time requirements for protection and control applications.

What Is Relay? How Relay Works?
A Relay is a simple electromechanical switch. While we use normal switches to close or open a circuit manually, a Relay is also a switch that connects or disconnects two circuits.
Critical role of time synchronisation in IEC 61850 based digital
Many devices offer multiple ways to synchronize device time, providing different or higher-accuracy synchronization. This article discusses some of these time-synchronization needs.
