Installation guide for power drive systems
30 October 2012
GAMBICA and REMA have updated their joint publication titled ‘Installation Guidelines for Power Drive Systems’, which is available free of charge as a download from the GAMBICA website.
Acceptable operation of a drive system is dependent on a satisfactory installation. Compliance with the appropriate EU directives and with local regulations is also a legal requirement.
Each section in the latest guidelines covers the requirements for a different part of a power drive system, to assist specifiers and purchasers from specification to installation and commissioning.
The new document follows a study carried out by GAMBICA and REMA, taking note of well-established fundamental theory and technical papers and incorporating the results of specific investigations carried out as part of the process. It principally considers the aspects of safe mechanical and electrical installation and the avoidance of EMC problems.
Commenting on the publication, Steve Brambley, deputy director of GAMBICA and convener of the organisation’s variable speed drive (VSD) group, said: “This is the 4th Edition of the Technical Guide, with updates on power drive systems including the drive, motor and load, together with cabling, site considerations, circuit protection, earthing and harmonics.
“Power Drive Systems is an IEC term which covers the VSD, motor and sensors used for feedback control information to the drive, as well as auxiliary parts like filtering and protection. The technical guide has now evolved into a comprehensive treatise for engineers and installers, giving them a VSD manufacturer’s perspective on best practice for installation.
“Since the 3rd Edition, it has been updated with reference to current legislation, regulations and standards, and with new sections on earth loop impedance testing, bearings and power conditioning, as well as an updated section on transformers.”
