Power quality: problems and solutions
- COURSE OUTLINE
- SPEAKER BIO(S)
As a result of this course, you will be able to:
- Define what constitutes a power quality issue.
- Explain the effects of power quality disturbances on different types of electrical equipment.
- Identify various types of power quality disturbances and their solutions.
- Describe a common power quality disturbance.
- Discuss various power quality mitigation solutions and the associated advantages and disadvantages.
Foundational knowledge of commercial and industrial electrical systems and equipment operations is required.
Who should attend?
Electricians, engineers, operators, contractors, facility managers, account managers and representatives, electrical service planners, new construction workers and anyone involved in operating or managing electrical equipment and systems where electrical power quality is a concern.
When it comes to the quantity versus quality debate, both are of equal importance when it comes to power. Join us to gain a solid understanding of electrical power quality and its impact in facilities. You’ll learn about common power quality disturbances and their origins, as well as how to improve power quality, immunize equipment and control disturbances. We’ll explain how to determine whether electrical supplies and equipment are operating within industry standards and how to distinguish between power quality disturbances that are normal and those that are not.
Electrical power quality is critical to every facility’s operation. We’ll explore what power quality disturbances are and at what magnitude industry standards consider them to be problematic. In addition, we’ll discuss numerous possible sources of power quality problems, the advantages and disadvantages of different types of power quality solutions, as well as protective equipment for particular disturbances.

Power quality overview
- Why so many problems now?
- Residential, commercial and industrial difficulties with power quality
- What constitutes a problem versus good power quality?
Managing the power quality issue as a utility
- The “people” aspect of power quality
- The correct response; who, what, when, where and how?
- Explaining “our side” and “your side” of the meter issues
Common disturbances: sources and impacts on equipment
- The six disturbance categories according to Institute of Electrical and Electronics Engineers; interruptions
- Short and long term voltage fluctuations, voltage unbalance, waveform distortion; harmonics, noise/interference, frequency fluctuations
Power quality sources: where do they come from?
- Internal to customer: wiring systems and customer equipment
- Trip settings on equipment/common wiring and grounding problems
- External to customer: power supplier system versus neighboring customers
- Switching, fault clearing, overcurrent protection device operation
- Blown fuse on capacitor bank, neighboring customer issues
- Combinations–both internal and external sources
Power quality standards: how much is too much?
- What are the regulatory and tariff requirements?
- ANSI/RUS C94.1, IEEE 519, NEC, CBEMA/ITE
- What do these things really mean?
How do you identify a power quality problem?
- Power quality measurement: VOM, power quality recorders, harmonic distortion
- Test procedures: placement, measurements, testing duration, interpreting data
Power quality solutions
- Improve the supply: maintenance, grounding, lightning protection
- Immunize the equipment: end use design, equipment standards
- Control the disturbance
- Power enhancers
- Power synthesizers

Greg has served as executive director of the Texas Agri-Business Electric Council—a liaison between the electric utility companies in Texas and Texas A&M University providing specialized training courses and technical assistance to member companies.
“How do I know I have “dirty power” if I can’t see it, smell it, taste it or touch it?”
“We used to think of power quality in terms of “are the lights on or off.” In modern buildings today there are electrical disturbances we never see that disrupt operations fast enough to be measured in micro-seconds.”
