About This Course

Power quality refers to the ability of the power grid to provide a stable power supply. The power
flow should have a pure sinusoidal waveform and remain within specified voltage and frequency
tolerances. With the rise of smart grids and technological advancements, there has been an
increase in electronic equipment, components, and devices, which can lead to harmonic distortions.
These distortions can disrupt the electrical network, due to which advanced mitigation
strategies are implemented to prevent downtime and outages.

Reactive Power Management & Power Factor Correction training course provides a detailed and
systematic overview of the concepts and principles of operation and application of protection
schemes for various power system elements. This course is well-structured and emphasizes
practical aspects of protection systems, including testing and coordination. Participants will gain
a thorough understanding of how to effectively implement and maintain protection systems in
real-world scenarios.
