A short duration of increased voltage.
A momentary and sometimes destructive increase in the amount of voltage delivered through a power line.
A sharp transient increase of current, voltage or power flow in an electric circuit or across an electric system.
(1) Long-interval variations in velocity and pressure in fluid flow, not necessarily periodic, perhaps even transient in nature. (2) The name applied to WAVE motion with a period intermediate between that of an ordinary wind WAVE and that of the TIDE. (3) Changes in WATER LEVEL as a result of meteorological forcing (wind, high or low barometric pressure) causing a difference between the recorded WATER LEVEL and that predicted using harmonic analysis, may be positive or negative.
Transient current or voltage associated with lightning or switching
A brief transient wave of voltage, current or power in an electrical circuit, lasting for less than 1% of the power wave cycle duration.
A transient prominence produced by flares or very active regions, appearing as a moderate to large collimated jet of gas rising up from the surface. Surge ejected gas will often fall or draw back onto the sun tending to follow magnetic field lines, while at other times it will rise and disperse, fading from view.
Rising and falling of the sea, usually due to wave action
A short-term increase in incoming voltage, typically lasting at least 1/120 of a second. Surges are usually caused when items that draw a large amount of electricity (air conditioners, refrigerators, copiers, etc.) are turned off. The extra power that these items were using is then released back into the power lines. Surges occur frequently, but can be of such short duration, that you may not notice them. Surges can cause damage to your computer, as well as corrupt your data.
Any voltage increase above 110 % of the normal voltage carried by a power line. See sag, spike, and oscillation.
A rapid increase in voltage or current by a power source. Can destroy a timer if not limited. Temperature range end limits (Tolerance) – The minimum and maximum temperature which can not be exceeded during storage or operation in order to assure reliable operation of device.
Waves of high and low water pressure moving through the pipes. Also, see water hammer.
An abnormally high voltage lasting for a short period of time.
A sudden increase in line voltage of short duration that can sometimes cause damage to electrical devices.
rise and move, as in waves or billows; "The army surged forward"
rise rapidly; "the dollar soared against the yes"
rise or move foward; "surging waves"
rise or heave upward under the influence of a natural force such as a wave; "the boats surged"
a gentle rise compared to the waves on top of it, which can batter buildings and other structures, Suhayda said
a longer, larger and considerably more dangerous spike
a momentary raising of the power level above its correct level
an over-voltage situation
a spike in the electric voltage level being used in homes, businesses and industries
a very short deviation from the normal working voltage
a transient rise of pressure or flow.
Transient over-voltage with a duration of less than 8.3 mS (one half cycle of the normal mains waveform).
A voltage increase lasting for several cycles or more. (See Overvoltage and Spike.)
A sudden dramatic increase in voltage that typically lasts less than 1/120 of a second.
A type of electrical overstress. In the absence of protective devices, the magnitude of the peak voltage of a surge is usually understood as at least twice the normal system voltage, and the duration of the overvoltage is less than a few milliseconds. (The word "surge" is also used by some engineers and technicians to indicate what should properly be called a swell.)
An oversupply of voltage from the power company that can last up to several seconds.
A sudden, transient increase in the flow of electricity.
Rapid increase in flow which may result in an attendant pressure rise.
A large, momentary, increase in the voltage on a power line.
Surge is the sudden rise in voltage in a system, usually caused by load disconnect.
surges are an increase in "normal" electrical line voltage. Usually not more than 500-600 volts.
An oversupply of voltage from the power company, lasting as long as several seconds. A strong surge can damage electronic equipment.
A short-term positive change in amplitude of a voltage.
A transient wave of current, voltage, or power in the electric circuit. Note: A transient has a high rate of change of current or voltage in the system.
A rapid rise in current or voltage, usually followed by a fall back to a normal level. Also known as transient.
A period of higher than normal voltage, causing incandescent lights to burn out and other problems.
A short term voltage increase that exceeds established upper limits for several cycles or more. Often confused with Spikes or Transients which last less than 1/2 cycle.
A transient (or momentary) wave of current, potential, or power in an electric circuit.
A surge is a prolonged over-voltage condition. Surges can damage electronics and corrupt or destroy data.
A surge is a short transient wave of current/power in an electrical circuit.
A moderate-duration perturbation on a power line, usually lasting for hundreds of milliseconds to several seconds.
Also called a "transient," it is the temporary and relatively large increase in the voltage in an electric circuit or cable.
A brief fluctuation in power, potentially harmful to electric and electronic equipment.
A brief increase in the voltage that powers home theater components. Surges are caused by lightning strikes or utility company power distribution problems. Surges not only travel on the AC utility line but every line that connects TVs and home theater systems to the outside world, including coaxial, antenna, satellite, phone and network lines. Depending on the severity of the surge, it can cause a TV or component to reset or can cause catastrophic, irreparable damage. Surge Suppressors and UPS Systems both provide protection against surge damage.
Line voltage exceeding 110% of nominal value.
a transient wave of current, voltage, or power in an electric circuit. A transient causes a high rate of change of current or voltage in the system, but lasts for only a short amount of time.
A single, non-repeating voltage distortion of less than 0.5 cycles in duration. (Also called "Spike," "Transient," or "Voltage Impulse."
An increase in the peak voltage waveform, at the same nominal frequency, lasting longer than one-half of a cycle. For a 60 Hz system the duration is longer than 8.33 milliseconds.
A temporary large increase in the voltage or current in an electrical circuit or cable.
A sudden current or voltage change in a circuit.
A momentary rise of pressure in a circuit.
A sharp, transient variation of current or voltage in an electric circuit or across an electric system.
Surge (Noriko "Nori" Ashida) is a fictional character, a mutant in the Marvel Universe, one of the student body in the Xavier Institute, and a member of the former New Mutants squad therein. She maintained her powers post M-Day and is the leader of the New X-Men. She first appeared in New Mutants (volume 2) #8.
