The intention of this course is to show how harmonics are generated by modern electrical and electronic systems. It starts with classical harmonic generators and some older electronic devices. It emphasizes single phase systems and how harmonics are generated by diodes, silicon controlled rectifiers, and triacs.
Special emphasis is made of the fact that it is the harmonic currents that flow that cause the harmonic voltages to be present. These harmonic voltages can affect other equipment, and even other customers on the electric grid. Many pictures and graphs are presented to show how harmonics can be present. At times, it is not at all obvious that harmonics are present in a signal. Even if they are not seen, the harmonics can cause problems for the power companies, which have the responsibility of delivering clean usable power to their customers.
This course was designed for electrical engineers as well as engineers of other disciplines. Electrical engineers will have a deeper understanding of how harmonics are generated. Engineers from other disciplines will get an idea of the problems faced by the people responsible for delivering power to their facilities. This will help engineers understand each other's special problems. The more that we, as engineers, understand the problems faced by other engineers, the better that we will be able to do our specific jobs.
There is very little math involved in this course. Graphs were generated by use of Excel programs. It helps, but is not necessary, to understand how Excel can generate graphs and charts.
Special Note: Course E-3018 and course E-2011W are alternate presentations of the same course material. Therefore, only one version, either the course or webinar, can be taken during a renewal cycle. If you have any questions regarding course eligibility, please contact our Customer Service Team.
