Primers

Power Quality in Low Voltage Installations - Voltage Dips - David Chapman, Copper Development Association

Voltage dips are the most common power quality problem and are also the most obvious since their result is usually instantaneous. For many industries a dip can be as financially damaging as a complete power failure. This presentation looks at the causes and effects, examining typical network performance, equipment performance and the compatibility gap between them. This gap must be covered in practice by good installation design and the right choice of mitigation equipment.

Power Quality in Low Voltage Installations - Harmonics - David Chapman, Copper Development Association

What do harmonic waveforms look like, and what kind of loads produce them? What typical harmonic profiles can be expected, what problems do they cause, and what mitigation measures can you use? This presentation helps to answer these questions.
