Beware Dirty Power

randmWhether personnel refer to it as a surge, a sag, a spike, a transient, a fluctuation, an interruption, or noise, “dirty power” reflects an abnormality in the electricity that runs a facility.

According to insight from Vertiv, formerly Emerson Network Power (vertivco.com, Columbus, OH), dirty power originates outside of and within a facility. Sources include lightning, utility switching, capacitor switching, and faults on the utility’s distribution system, all of which can affect the quality of power before it even reaches the plant’s internal system.

Vertiv’s experts note that daily fluctuations from internal electrical equipment, such as devices that run in cycles or get turned on and off frequently, can cause cumulative and equally damaging power hazards. Even a small appliance can lead to problems with sensitive equipment that shares the same line. What’s worse, the more electrical equipment a site uses, the more transients accumulate. MT
