Training course overview

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. This Power Quality and Reliability training course will enusure that your Power Systems Meet Customer Expectations.

This Coventry Academy training course will feature:

  • 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

What are the goals?

By the end of this Coventry Academy training course, participants will be able to:

  • Understand common power quality and reliability terms
  • Know how to assess the impact of voltage sags on sensitive electrical equipment
  • Comprehend the influence of fault clearing on voltage stability
  • Calculate and use standardized reliability indices
  • Understand the sources of transient overvoltages and be able to specify arresters
  • Know why harmonics are produced and be able to implement mitigation methods
  • Analyze the components of AC power and understand the relationship with voltage regulation

Who is this training course for?

This training course is designed for utility, plant, or consulting engineers and technicians who work with transmission or distribution systems, or facilities that utilize electrical power.  If you are beginning a career or assignment in these areas, this training course will be of value to you. Those responsible for improving system reliability or resolving power quality issues will find this training course especially helpful.  Topics will begin at the fundamental level and move to more advanced content as the training course progresses. Prerequisites include a basic understanding of three-phase power systems.

This Coventry Academy training course is suitable to a wide range of professionals but will greatly benefit:

  • Engineers and technicians new to the power industry
  • Intermediate-level engineers and technicians who seek to improve system reliability
  • Professionals involved with the assessment of power quality
  • Facility engineers and consultants responsible for mitigating power quality issues
  • Engineers tasked with monitoring system performance and reliability

How will this training course be presented?

This Coventry Academy training course will utilize a variety of proven adult learning techniques to ensure maximum understanding, comprehension, and retention of the information presented. These methods include workshops where attendees practice solving problems (bring a scientific calculator), case studies where concepts covered are applied to real-world situations, and simulations and animations to visually illustrate what would otherwise be abstract concepts in a novel and intuitive manner.
