A condition where the voltage supplied to the system falls below the specified operating range, but above 0V.

In response to heavy demand, main system voltages are sometimes lowered, leading to brownouts in which power is not lost but reduced.

The partial reduction of electrical voltages caused by customer demand being higher than anticipated or by the failure of the generation, transmission, or distribution system.

period of reduced voltage of electricity caused by high demand or other factors.

A dip in the voltage level of a power system, which can damage electrical equipment or cause it to under perform, eg, lights dim. (See Voltage drop.)

A deliberate lowering of line voltage by a power company to reduce load demands.

Term describing a power reduction (as opposed to a total failure), which causes a maloperation in computer hardware or other electronic equipment. This can damage equipment and can be prevented with a UPS. browser

(n) darkness resulting from the extinction of lights (as in a city invisible to enemy aircraft)

 - Refers to a reduction of voltage on the system. This dims the lights as a means of conserving energy.

A temporary reduction of voltage supplied by the electric company. Typically causes lights to dim.

Also known as voltage reduction

A temporary reduction of voltage supplied by the electric power distributor.

A reduction in voltage and/or power when demand for electricity exceeds generating capacity. The term brownout is misleading because customers generally do not notice the reduction, except when it affects sensitive electronic equipment.

A small, temporary voltage reduction implemented by a utility to conserve electric power during periods of high use.

Abnormally low voltage that causes voltage-sensitive equipment such as computers, motors and certain types of lighting to have degraded or interrupted performance.

An intentional reduction of energy loads in an area by the partial reduction of electrical voltages.  A brownout results in the dimming of lights and slowing of motor-driven devices.

A low voltage condition lasting longer than a few cycles. “Brownouts” differ from “sags” only in duration.

enforced reduction of electric power usage.

 Prolonged sag, occurring when incoming power is reduced for an extended period. Usually caused when demand is at its peak and the line becomes overloaded.

A condition resulting from lower than normal voltage, duration can be minutes or even hours. Caused by weather, animals, or motor vehicles interfering with distribution equipment.

A reduction in commercial voltage level that may be a result of an overload on the system.

Common term for under voltage, taken from the coloration of filament style light bulbs during under voltage conditions. See under voltage

The failure of generation, transmission or distribution systems resulting in partial reduction of electrical voltages for short durations.

A long duration reduction in the voltage of the ac supply without complete loss of power. Brownouts are usually caused by heavy usage during peak hours and sometimes may even be planned as an energy conservation strategy. *brownout A controlled power reduction in which the utility decreases the voltage on the power lines, so consumers receive lower [..]

A period of low alternating current line voltage, causing a reduction in illumination ''When demand for electricity exceeds the available supply, a brownout occurs.'' Temporary dimming of vision [..]
