Course Introduction
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.
