Data Center Power Quality

Power quality problems have increasingly become a substantial concern over the last decade, but surprisingly few analytical techniques have been developed to overcome these disturbances in system-equipment interactions.

Power quality problems are common and can come from a variety of different sources. The definition of power quality is simply the interaction of electrical power with electrical equipment. If electrical equipment operates correctly and reliably without being damaged or stressed, we would say that the electrical power is of good quality.

On the other hand, if the electrical equipment malfunctions, is unreliable, or is damaged during normal usage, we would suspect that the power quality is poor.
As a general statement, any deviation from normal of a voltage source (either DC or AC) can be classified as a power quality issue.
