ABB Ultra Low Harmonic Variable Speed Drives

Understanding Harmonics To appreciate the full benefits of ABB’s Ultra Low Harmonic drives, it’s necessary first to understand the concept of harmonics. Essentially, harmonics are unwanted currents that flow within a power system, caused by non-linear electrical loads. Non-linear loads, such as variable speed drives, switch power on and off abruptly to control the output. This action can cause a distortion of the electrical waveform, resulting in harmonics. Harmonics have the potential to impact negatively…

What is it Harmonic Distortion and where does it come from?

For this blog article we are delighted to have George Dodwell, ABB Water Framework Manager – South, explain harmonic distortion and where it comes from: When we look at harmonic distortion (most often known simply as “harmonics”), I feel it’s best to start at the beginning and understand what it is and how it is generated. We will also discuss why harmonics are potentially an issue and why they can cause problems with an electrical…

Harmonic lessons learned

Here ABB’s Martin Richardson reflects on feedback from the water industry on the issue of harmonic mitigation. Four years ago, ABB received CPD accreditation for a training course that looked at the effect of harmonics on the operation of water plants and ways in which their impact could be mitigated. The course targeted water industry end-users and was a sell-out. Feedback revealed the confusion and misunderstanding surrounding the subject of harmonics. Harmonics often get the…

Harmonics Training Gains Rave Reviews

On the 14th May 2019 we hosted an ABB training day on Harmonics and Mitigation Methods for the Water Industry. The interest for the training was very high, both morning and afternoon sessions were fully booked within a day of publishing them, prompting us to add another date. The Course Itself The training day was split into two sessions, a morning and an afternoon session with both sets of delegates invited to share lunch. IDS…

Harmonics and Mitigation Methods for the Water Industry

New Date Added! Due to the high level of response we received we have added another date for the Harmonics and Mitigation Methods for the Water Industry training course. The first day was booked up in just two days, so we decided to add another on: Wednesday 12th June 2019 IDS are hosting a half day training event on Harmonics and Mitigation Methods for the Water Industry. These half day training sessions will be presented by…

Harmonic Pollution in the Water Industry

This week we feature a recent article from ABB’s water industry manager for UK & IE, Stuart Foster. Writing in Drives & Controls, Stuart explains the challenges Water Companies face when it comes to harmonic pollution: “Have you noticed how a single word can mean one thing in one context, but something totally different in another? Take harmonics for example – to a singer, it means the ability to sing more than one note at…
