Introduction
Training course introducion / brief
This 5-day boost training course will introduce the concept of harmonics production and their effects on different equipment supported with practical examples problems of harmonics in industrial plants are considered among the biggest issues in industrial distribution systems. Understanding harmonic recommendation ieee 519 will be presented. Ac drives, pwm and inverters will be covered in detail. Effect of equipment loading on harmonic currents and total harmonic current distortion will be illustrated with examples using solv software. Harmonics mitigation techniques; reactors, commutation reactors, special reactors passive l-c filters, phase shifting, phase staggering, active filters, hybrid active/passive filters and active front ends will also be covered.
As a practical part of the course, local site measurements using harmonic measurement equipment will also be done.

COURSE METHODOLOGY
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.
Since 2001, we have been pioneering the training field in the middle east, we managed to unlock potential and help individuals, teams and organisations to be the best that they can be with our full and integrated solutions.
