Operating an energy boundary in the presence of bad Power Quality Indices (such as the Total Power Factor, Current / Voltage Unbalances, Harmonic Distortion etc.) generates avoidable energy losses.

Oh, well, Power Quality cannot be measured. As per se. What can be measured and we measure are various intermediary values. They describe the current and voltage waveform.

Bad/poor/low, you name it, Power Quality can have a negative impact on the electrical system, and not just, and, most likely, it will have it.

If you are a maintenance / building / production manager, this one is for you. If (and only if) you want to lower energy usage and costs, of course.
