Power Quality Training

Power Quality Training

Our 2-day course is important because power quality and harmonics analysis, measurement, and mitigation of electrical disturbance is no longer an option in our modern electronic society, it is a necessity.

Our power quality seminar discusses the concepts of proper power quality as well as the negative effects of poor power quality.

Students will learn what power quality entails and who all the relevant stakeholders are. Furthermore, students will learn what the possible effects are of poor power quality and what the direct and indirect costs are of poor power quality on industrial power systems.

From microwave towers feeding data to corporate offices, modern data management centres, telecommunications networks, industrial, commercial and institutional power systems all demand uninterrupted, uncorrupted electrical electricity. As much as 40 per cent of electrical maintenance issues can be attributed to transient voltage spikes, voltage dips, brownouts and outages. Did you know that the average computer site experiences 38 power interruptions per year, and that 94 per cent of those interruptions are less than five minutes in duration.

Microprocessor-based industrial controls - PLCs, industrial computers, HMI, drives, motion controllers and sensors - are the foundation of high productivity, quality and competitiveness. If there is one universal factor that can and will disrupt microprocessor-based controls and cause downtime, it is power quality. Since industrial electrical systems frequently experience voltage fluctuations, harmonic distortions, noise and short- or long-term power outages, it is essential to ensure maximum uptime. The ability to quickly identify and remedy power quality problems will help ensure metering accuracy, lengthen the life of electrical equipment and improve power system availability.

Power quality failures are expensive and can significantly impact the bottom line of an organization. Electrical engineering and maintenance personnel have long been aware that identifying, monitoring and correcting power quality problems is vital to keeping facilities and processes running smoothly. This forum offers electrical professionals the opportunity to keep abreast of the latest technologies and techniques available in this area. It also offers an excellent opportunity for delegates to ask specific questions and exchange ideas relating to their own applications. This is designed to be an interactive, problem-solving, learning environment for delegates of all disciplines.


Harmonics Problems Cause:

  • Increased losses, e.g. machines will operate at increased temperature and can be overheated
  • Resonance problems between the inductive and capacitive parts of the power network
  • Malfunctioning of control systems since electronic meters, relays, etc. are matched to the fundamental frequency
  • Overloading of capacitors, leading to malfunctioning and premature aging
  • Interference with telecommunications and computers
  • Disturbances in ripple control systems
  • High currents in neutral conductors.



  • Recognize symptoms of power quality problems including sags, swells, under or overvoltage, harmonics, transients, electrical noise (EMI/RFI/EMF), interruptions, wiring and grounding issues
  • Classify power quality events according to IEEE, ITIC (CEBNA) and public utility standards
  • Collect the required data to perform a detailed coordination study
  • Explain proper application and interpret results of power quality monitoring equipment
  • Recommend viable solutions including UPS, line voltage regulators, transient (surge) suppressors, harmonic filters, line filters, power conditioners, k-rated, isolation and zig-zag transformers, proper wiring and grounding, etc.
