Time synchronisation
The needs and exact precision of time synchronization in IEC 61850 based digital protection systems have evolved. With new technologies and better distribution methods, most modern intelligent electronic devices (IEDs) include at least one form of time synchronization.
Many devices offer multiple ways to synchronize device time, providing different or higher-accuracy synchronization. This article discusses some of these time-synchronization needs. Precision time synchronization is gaining popularity in the electric power industry, with a number of new applications promising to improve power system operation.

Hi, I'm an electrical engineer, programmer and founder of EEP - Electrical Engineering Portal. I worked twelve years at Schneider Electric in the position of technical support for low- and medium-voltage projects and the design of busbar trunking systems.I'm highly specialized in the design of LV/MV switchgear and low-voltage, high-power busbar trunking (<6300A) in substations, commercial buildings and industry facilities. I'm also a professional in AutoCAD programming.
