A short duration of increased voltage.

A short duration high voltage condition. A surge lasts for several cycles where a transient lasts less than one half cycle. Often confused with “transient”.

surges are an increase in "normal" electrical line voltage. Usually not more than 500-600 volts.

A short-term increase in voltage, typically lasting at least 1/120 of a second.

A sudden voltage rise and fall in an electrical circuit.

The difference in height between predicted and observed tides due to abnormal weather conditions. See Admiralty Tide Tables. See also positive surge, negative surge, storm surge.

    A very rapid increase of current or voltage.

A transient rise of pressure or flow.

Also called a "transient," it is the temporary and relatively large increase in the voltage in an electric circuit or cable.

A surge is a prolonged over-voltage condition. Surges can damage electronics and corrupt or destroy data.

An increase in pressure that occurs for a specified short period of time over the normal expected working pressure.

the sudden displacement or movement of water in a closed vessel or drum.

Overvoltages lasting longer than 1/60th of a second. Can be caused by the automatic switching on or off of motor driven devices, a lightning strike on or near a power line, or even something as simple as the discharge of static electricity build up on a copier from the shuffling of paper.

A transient variation of current, voltage, or power flow in an electric circuit.

Overvoltages lasting longer than one-sixtieth of a second, often caused by the automatic switching on or off of motor-driven devices or lightning strikes near a power line.

An abnormally high voltage lasting for a short period of time.

A sudden increase in liquid pressure caused by a sudden reduction of flow.

To loosen a line on a turning drum so that friction is temporarily lessened and the line remains stationary.

To ease a line to prevent it from parting or pulling, meanwhile holding the strain.

To ease a line to prevent it from parting or pulling, meanwhile holding the strain.

Rising and falling of the sea, usually due to wave action. A vessel's transient motion in a fore and aft direction.

Rising and falling of the sea, usually due to wave action.

A vessel's transient motion in a fore and aft direction.

To allow the cable or hawser to run out under its own weight. The term is often used when handling mooring ropes on drum ends. (You should not surge on man-made fibre ropes, because of the possibility of heat/ friction causing the yarns/strands to fuse.)

A vessel's transient motion in a fore and aft direction.

A vessel's transient acceleration and deceleration in a fore-and-aft direction. Compare to Pitch, Roll, Yaw, Headway, Sternway, Leeway, Drift, and Heave

Rising and falling of the sea, usually due to wave action.

When a rope renders round a belaying pin, &c.  

A phenomenon in centrifugal compressors where a reduced flow rate results in a flow reversal and unstable operation.

A rise in water level caused by strong wind or fluctuations in the atmospheric pressure. This term is usually applied to a sharp set-up effect at the downwind end of the lake, but thunderstorms can cause brief local storm surges in bays and harbours. See Set-up.

In solar-terrestrial terms, a jet of material from active regions that reaches coronal heights and then either fades or returns into the chromosphere along the trajectory of ascent.

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 [..]

An occurrence in which reduced flow rate leads to flow reversal and unsteady operating in compressors.

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 jet of material from active regions that reaches coronal heights and then either fades or returns into the chromosphere along the trajectory of ascent. Surges typically last 10 to 20 minutes and tend to recur at a rate of approximately 1 per hour. Surges are linear and collimated in form, as if highly directed by magnetic fields. definition cou [..]

In solar-terrestrial terms, a jet of material from active regions that reaches coronal heights and then either fades or returns into the chromosphere along the trajectory of ascent.

The increase in sea water height from the level that would normally occur were there no storm. Although the most dramatic surges are associated with hurricanes, even smaller low pressure systems can cause a slight increase in the sea level if the wind and fetch is just right. It is estimated by subtracting the normal astronomic tide from the observ [..]

An unstable operating condition when the flow through a compressor is decreased to the point that momentary flow reversals occur. Can lead to major damage of compressor. Further Reading

The sudden change in voltage or current in a circuit. Surge current is a sudden change in line current to a user equipment that occurs during start-up or as a result of a change to the operating mode.

The sudden displacement or movement of water in a closed vessel or drum.

A transient (or momentary) wave of current, potential, or power in an electric circuit. The word "surge" has different meanings to different engineering communities. To the protection engineer a "surge" is a transient overvoltage with a duration of a few microseconds, i.e., a spike. To others a "surge&am [..]

A sudden change (usually an increase) in the voltage on a powerline. A surge is similar to a spike, but it lasts longer.
