Your company is worried about instability in the electrical power provider it uses. Occasionally voltage dips below expected levels causing issues for computing infrastructure. What term defines this situation?
A brownout is when voltage drops suddenly below the expected levels causing intermittent issues for electrical devices. A power surge is the opposite (increase in power) and a blackout is a total loss of power.
A brownout is a drop in voltage in an electrical power supply system.
Unintentional brownouts can be caused by excessive electricity demand, severe weather events, or a malfunction or error affecting electrical grid control or monitoring systems. Intentional brownouts are used for load reduction in an emergency, or to prevent a total grid power outage due to high demand. The term brownout comes from the dimming of incandescent lighting when voltage reduces.
In some countries, the term brownout refers not to a drop in voltage but to an intentional or unintentional power outage (or blackout).
