The increasing use of equipment sensitive to power system disturbances and the related economic aspects, the increasing awareness of power quality issues and deregulation have created a need for understanding the causes of these problems and the ways to solve. The course covers the Power quality issues, power frequency disturbances, electrical transients and earthing systems in electrical power systems.
The course concerns the sources of distortion (loads) and the interaction between those and the propagation of the distortion in the power system. Effects on the power system are also indicated. Harmonics, its effects on electric power system and how to overcome are highlighted.

Our Training programs are implemented by combining the participants' academic knowledge and practical practice (30% theoretical / 70% practical activities).
At The end of the training program, Participants are involved in practical workshop to show their skills in applying what they were trained for. A detailed report is submitted to each participant and the training department in the organization on the results of the participant's performance and the return on training. Our programs focus on exercises, case studies, and individual and group presentations.
