Harmonics Seminar

Organisation profile

ABB is a global leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact.

ABB has five locations in Ireland operating five divisions namely Power Systems, Power Products, Low Voltage Products, Discrete Automation & Motion and Process Automation where staff are involved in Sales, Technical Support, Engineering and Project Management.

Training aim

The aim of this seminar is to help engineers to understand possible harmonic problems, the standards involved and how to mitigate power quality issues.

Learning objectives

This course aims to show the effects of harmonics can have on overheating of transformers, cables, motors, generators and capacitors connected to the same power supply with the devices generating the harmonics. Electronic displays and lighting may flicker, circuit breakers can trip, computers may fail and metering can give false readings.

Course outline

 Special attention will been given to the methods for reducing harmonics with VSDs.

Where do Harmonics come from?

What are Harmonics? - Mitigation Techniques

Bearing Currents - case study and example specifications

Practical examples using demo kit will form part of the workshop.

Trainer's profile

This seminar will be presented by Frank Griffith of ABB. Frank has been with ABB 23 years and is a Consultant in the Drives Applications Group. During this time he has been responsible for two "world first" and four "UK first designs; all variable speed drives applications". Frank‘s particular areas of interest are Power System Quality (harmonics) and use of Variable Speed drives for pumping applications. He is a member of the IET.
