The proliferation of computers and other sensitive devices throughout our
manufacturing and office environment has fostered the need to design the
electrical systems of buildings with an eye toward power quality issues. There
have been numerous books and articles concerning diagnosis and remediation of
power quality problems in existing structures after these problems have
manifested themselves.

The term "power quality" means different things to different
people. One definition is the relative frequency and severity of deviations in
the incoming power supplied to electrical equipment from the customary, steady,
60Hz, sinusoidal waveform of voltage or current. These deviations may affect
the safe or reliable operation of equipment such as computers.

Thus, while not having a strict basis of measurement, terms like "poor
power quality" generally mean there is sufficient deviation from norms in
the power supply to cause equipment mis-operation or premature failure.
"Good power quality", conversely, means there is a low level of such
deviations or mis-operations.

Poor power quality affects the reliable operation of
computers and computer-based equipment, which are now so ubiquitous. Often more
important than the physical effect on the equipment is the loss of productivity
resulting from computer equipment failure, mis-calculations and downtime.

The vast majority of power quality problems in a building originate within
the same building. The Institute of Electrical And Electronic Engineers (IEEE),
various government agencies and other organizations have been studying these
problems and effects for several years. As a result, they have issued design
guidelines and recommended practices that are known to greatly reduce, if not
eliminate, the incidence and severity of power quality related problems.
