How do PAYBACK variable speed drives influence power factor?
Some utility companies in certain locations may charge a penalty if the facility’s total measured power factor is below an acceptable pre-determined level. In hundreds and hundreds of installations, in many varied facilities such as colleges, schools, hospitals, government buildings, and shopping malls, power factor has never been an issue with the new shaft-mounted variable speed drives. However, in the rare event that power factor may require attention, low cost power factor correction capacitors can be easily installed at each motor location as required.
