Energy Savings and Power Quality: Complement or Contrast?

Ascott Hotel, Makati, Philippines

Energy Savings and Power Quality: Are they complementing or against each other? These topics are often commingled in papers and seminars. For example, loads used to conserve energy like variable frequency drives and efficient lights with electronic ballasts, in most cases affect power quality. This dilemma will be answered in this course, where the issue between energy savings and power quality will be expounded and explained – its causes, effects and solutions and more importantly how these solutions can generate savings.
