The facilities manager at a data storage company has been notified by his utilities provider that power voltages will be reduced periodically throughout the next few weeks because of demand issues. What type of condition will he be experiencing over the next few weeks?
A.
Blackouts
B.
Brownouts
C.
Surges
D.
Sags
Explanation:
Brownouts are planned reductions in power voltages due to problems with
supply and demand. Brownouts have occurred frequently in California over the past
few years as power companies struggle to keep up with demand.
I thought the answer would be D. I know that power sags are “Momentary” low voltage (which it sounds like in the answer) while a Brownout is a “Prolonged” low voltage.
With the answer being B, does this mean that Power Sags are all unplanned while Brownouts can be either unplanned or planned (or are they just planned)?
