Power Quality Training - Harmonic Analysis, Diagnostics, Mitigation

Why Power Quality Training Matters

This 12-hour instructor-led course is important because power quality and harmonics analysis, measurement, and mitigation of electrical disturbances are no longer optional in our modern electronic society; they are a necessity. The course is designed to help organizations recognize power quality problems by their symptoms and waveforms, and to understand their root causes and typical remedies.

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 costly and can significantly impact an organization's bottom line. 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 stay up to date on the latest technologies and techniques in this field. It also offers delegates an excellent opportunity to ask specific questions and exchange ideas related to their own applications. This is designed to be an interactive, problem-solving, learning environment for delegates of all disciplines.

Upon completion of this Power Quality Analysis Training course, students should have a meaningful understanding of various types of power quality disturbances associated with typical motor control applications. They should understand the causes of these problems, their symptoms, the problems associated with each, and the typical means of solving or preventing them.

Power Quality Training Course Overview

Our Instructor-Led Course offers:

• Explanation of various power quality disturbances.
• Explanation of the causes, symptoms, problems and solutions for each disturbance.
• Suggested Best Practices to prevent future problems.
• Recognizing Power quality problems through waveforms.

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.

THIS COURSE WILL ALSO TEACH YOU ABOUT:

• Voltage sags
• Power factor
• Voltage transients
• Harmonics
• Harmonic resonance
• PWM voltage and its effects on motors
• Long motor lead applications
• EMI in VFD environments
• Identifying power quality problems through waveforms

LEARNING OBJECTIVES

• 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 the 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.
