The advantage of investing in Variable Speed Drives (VSD’s) are well known, benefits of which include being energy efficient and extremely flexible in the controlling of processes and machinery using standard AC or PM motors.

However, increased problems elsewhere in the electrical system can arise, depending on the VSD installation. This can result in a loss of revenue as it can be very costly to resolve them. There are several basic checks that need to be completed during commissioning before the VSD is ready for energising. 

An investment in more experienced engineers during installation, selection and commissioning of VSD’s, has been proven to avoid any of the potential problems.
