Advances in measurement, communications and computing technology have now made it feasible and practical for largescale use of synchrophasor technology for real-time operations. Monitoring, Visualization, analysis and application based on high-speed, streaming phasor data is significantly different and advanced from traditional EMS systems which is based on snapshots of power metrics of a localized footprint. Adoption and use in real time operations requires training – fundamentals, theory and hands-on exercises.


Training requires time and resources. To address this need, EPG has developed a web based online training portal providing courses on synchrophasor technology which can be taken on demand, anytime, anywhere that internet access is available. The courses are developed to train engineers, planners, operators and others on synchrophasors and their use in operations. The web portal is designed for authorized users only and the courses include lectures, presentation slides, videos and interactive quizzes. The web training portal provides:


  • Online Training Courses on synchrophasor technology
  • Freedom to take courses online anywhere, anytime and from any device with just internet access
  • Ability to take the courses any number of times and repeated for shift engineers and operators to refresh their knowledge
  • Flexibility to add more training courses that are customized

“Introduction to Synchrophasors” Course:

“Introduction to Synchrophasors” provides an essential primer on synchrophasor (or phasor) technology. The course covers essential aspects of this technology – what is measured, the various components, terminology, concepts, advantages and uses.



The course provides a well-rounded understanding of synchrophasors. It consists of 5 sessions each focusing on a key area of synchrophasors, and together, the 5 sessions form a strong foundational understanding and awareness of the domain. Each session is of approximately 1 hr. of instruction. They are:
