Harmonics in Electric Power Systems

What You'll Learn

check_circleIdentify electrical loads that cause harmonic distortions in electrical power systems.
check_circleUnderstand how harmonic causing loads draw current from the power network. For the purpose of troubleshooting, select from a list of loads, the type that cause AC waveform distortions.
check_circleExplain what makes up dirty power. List the causes of dirty power. Describe the difference between a steady state disturbance and a short term disturbance. Understand that harmonics are only one component of what makes dirty power.
check_circleUnderstand the difference between an individual harmonic solution and a system harmonic solution. List available harmonic mitigating solutions for individual loads. List available harmonic mitigating solutions for systems. Explain the difference between an active harmonic filter and a passive harmonic filter.
check_circleSelect a K-rated transformer for a specific non-linear load type. List the design characteristics of K-rated transformers. Understand the basic design intent of K-rated transformers with respect to delivering harmonic load current. Explain the purpose of installing a K-rated transformer.
check_circleGain an understanding of the IEEE Standard for Harmonic Control in Electric Power Systems. Understand important terms applied to harmonic voltage and current limits such as: Point of common coupling (PCC). Total demand distortion (TDD). Short circuit ratio. Total harmonic distortion (THD). Maximum demand load current.
check_circleKnow the difference of how voltage and current distortion limits are applied to electrical systems. Know where the recommended voltage and current limits are applicable in an electric power system.

About This Course

About the Course

Please 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:

  1. Linear and Non-linear loads are discussed, and the importance of auditing loads is stressed, for the purpose of troubleshooting systems.
  2. Current and voltage harmonics are explained and demonstrated using measuring instruments.
  3. Total harmonic distortion and components that make up that distortion are explained. Distortion on current waveforms and the relationship between voltage distortion is explained.
  4. Harmonic components that make up a distorted signal are broken down to individual harmonics.
  5. Positive and negative sequence harmonics are discussed and the effects of these harmonics on electric motors is stressed.
  6. Triplen harmonics are explained along with the hazards that they pose on electrical distribution systems.
  7. K factor transformers are covered along with troubleshooting problems caused by harmonics.
  8. Harmonic analyzers, industrial scopemeter and hand-held instruments are discussed in this course.
  9. Passive and active filters used to minimize harmonics are discussed.

Norman Burton Education: My educational background is trades centric. I started a high school co-op in the early eighties and spent six years obtaining an Automotive Machinists’ license. Afterward, I started an Electrical Construction and Maintenance apprenticeship. Having successfully completed the academic portion of the apprenticeship at Durham College I became a C+M Interprovincial licensed Electrician in 1998. Working as an Electrician, I have completed numerous continuous learning programs such as: Arc Welding, PLC programming, Automation Technology, Teaching and Training Adults and a Masters Electrician Course. I became a licensed Master Electrician in 2007. Professional Experience: Working in the trades has been exciting and wide-ranging having worked in the construction, industrial and institutional sector. I have also spent considerable time working in the automation and controls sector. In 2007 I started an electrical business, Burton Electro Technical Inc. The business focus is primarily industrial controls, installations and troubleshooting. The business also builds electrical training equipment for learning institutions and private companies. Burton Electro Technical Inc. has customers throughout Canada and the United States. In addition to working in the Electrical industry I have been instructing part time since 2005 at Georgian College in the Electrical Apprenticeship program. While working in the Electrical Industry, I have travelled to the United States, Mexico, Japan, throughout Central Ontario and British Columbia. Current Endeavors: Owner / Operator Burton Electro Technical Inc. Instructing electrical apprenticeship programs part time at the Georgian College Skilled Trades Center in Midland, Ontario.
