Power Quality & Reliability Course

About This Class

Power quality determines reliability of electrical equipment operation, performance of the assigned functions by it, service life. Problems of power quality attracted increased attention because of power quality degradation and not meeting customer expectations. Poor power quality has been shown to lead to reduced efficiencies, increased risk of downtime and higher energy and operating costs.

When it comes to power quality issues, the easiest and most effective solution to avoid unplanned shutdowns is the correction of voltage anomalies coming from the grid. This can be accomplished using harmonic filters, capacitors and other protective equipment.

Rises in non-linear and other challenging loads in modern electrical networks present unique power quality challenges. Sensitive operations, irregular loads and isolated or weaker grids demand stricter grid codes and power quality standards to safeguard the reliability of an electrical system for smooth industrial and commercial processes. Harmonics distortions, voltage variations, poor power factor and load unbalance are among the key elements that not only test the reliability of modern electrical systems but also induce overall greater system losses.

Main course features are:

• Basic terminology and definitions
• Voltage sags and interruptions
• Effects of fault clearing on voltage
• Reliability indices
• Transient overvoltages and arresters
• Understanding and mitigating harmonics
• Analysis of AC power and steady-state voltage regulation

Professor J. Walker is the director of a technologies company that specializes in consultation on High Voltage insulation testing as well as the supply of test equipment for High Voltage applications. He is a Doctor of Technology graduate from the Vaal University of Technology, completed in 2005 with a thesis titled “Diagnostic Evaluation of Water Tree Aged XLPE-Insulated Cables”.

He started with a Higher National Diploma in Electrical Engineering acquired at Vaal Triangle Technikon where he later worked as a lecturer in the Department of Power Engineering after completing his Bachelor of Technology Degree. In 2005 Professor Walker was appointed as Associate Professor at Vaal University, and subsequently the head of the Institute for High Voltage Studies, a position he held until his retirement the following year.

He has over the years of acquiring field and academic experience; he also published a number of articles and journals on electrical power systems, and has presented a number of papers at local and international conferences.
