Last month, I covered the challenges to traditional structured cabling from multimode optical fiber and wireless. Multimode fiber became the favorite cabling for the backbone but never made it to the desktop because every connected device already had a free Cat 5 port.

In this third part of my series on the most common power quality phenomena, I group several IEEE 1159 categories together under the general description of “distortion.” Though one might argue that all power quality phenomena result in distortions of the voltage sine wave, these are the more steady-s
