Summary
Precise time synchronization is a fundamental requirement for IEC 61850-based digital substations, where the transition to process bus architectures has pushed accuracy demands to the sub-microsecond level. Although the Precision Time Protocol (PTP) is the industry standard, its implementation introduces significant technical complexity that transcends traditional power system engineering.

Grandmaster clock re-selection create a steep learning curve for utilities. By integrating technical standards with simulation results, this paper demonstrates how simulation models serve as dynamic knowledge repositories. The study offers recommendations to bridge the gap between power engineering and communication networks, providing a strategic approach to expertise management in the transition toward digital substations.
