Electrical, Renewable Energy, Power, DCS Training Courses

Energy Audit & Management


This training course explores the topic of power quality and its effects on the reliability of the electrical system. Power quality is first precisely defined, because, without a precise definition, measurements of baseline conditions and assessments of improvement are impossible. Then methods of evaluating reliability are investigated. After completing this course, you will have a thorough understanding of how power quality and reliability can be measured, and how changes made to the electrical system will affect these important properties

Targeted Groups:

  • 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

Course Objectives:

At the end of this course the 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
