Managing the reliability of VSDs

Martin Richardson, ABB’s water framework manager for the UK, examines and assesses various approaches to maintenance to determine which is the most cost-effective for variable-speed drives.

The power of adaptive programming

You may not be familiar with the term, “adaptive programming”. But, as Andy Preston, ABB’s UK drives product manager, explains, it can be a lifesaver in some VSD applications, helping to resolve technical challenges and to cut costs.

Don’t forget the installation basics

Poor installation is often to blame for VSDs failing in service. Andy Preston, ABB’s drives product manager in the UK, runs through some of the common reasons for VSD failures – and offers suggestions for avoiding such failures.

Think before you buy energy-saving equipment

Before installing energy-saving drives and high-efficiency motors, you need to examine carefully the system in which they will be used. Frank Griffith, a drives consultant with ABB in the UK, offers advice on what to look for.

Harmonic filters – where size matters

Frank Griffith, a consultant engineer with ABB in the UK, looks at some of the factors that affect the sizing of harmonic filters for drives. Griffith has extensive experience of designing drive systems with several pioneering designs to his name. He is an MIET and and a lecturer on drives topics
