Power factor correction and power quality projects completed by Power Quality Improvement Services Ltd.

Many PQIS customers require us to conduct a power quality survey of incoming LV electricity supplies to specify power factor correction equipment and power quality solutions. We then manufacture and install recommended equipment or implement solutions for cost effective energy efficiency solutions. We have provided details of some PQIS power quality projects below.
