About the CoursePlease Note:This is not a power engineering course. This course is designed for practical applications - (troubleshooting & maintenance of systems) and harmonic mitigation solutions for individual loads. An overview of IEEE 519-2022 will be provided. IEEE 519-2022 sets goals for designing electrical systems that contain both linear and non-linear loads.Having an overview of IEEE-519-2022 will help you when working with Companies that may be installing system wide harmonics mitigation equipment in your facility.This course is designed to help Electricians, Maintenance Technicians and Facility Managers understand the cause and effect of harmonics on electrical systems. Electrical trouble-shooters will find this course useful and will be a great addition to their troubleshooting tool kit.The course explains how harmonics are created in an electrical system and lists the type of loads that cause harmonics. Information is presented in a simple concise manner without complicated mathematics. Simple methods for identifying and isolating harmonic causing loads are covered. Basic information along with the following are covered throughout the course:Linear and Non-linear loads are discussed, and the importance of auditing loads is stressed, for the purpose of troubleshooting systems.Current and voltage harmonics are explained and demonstrated using measuring instruments.Total harmonic distortion and components that make up that distortion are explained. Distortion on current waveforms and the relationship between voltage distortion is explained.Harmonic components that make up a distorted signal are broken down to individual harmonics.Positive and negative sequence harmonics are discussed and the effects of these harmonics on electric motors is stressed.Triplen harmonics are explained along with the hazards that they pose on electrical distribution systems.K factor transformers are covered along with troubleshooting problems caused by harmonics.Harmonic analyzers, industrial scopemeter and hand-held instruments are discussed in this course.Passive and active filters used to minimize harmonics are discussed.
