A sudden surge of high voltage on a power distribution circuit, usually caused by lighting or the switching on/off of heavy loads, especially motors.
a gradual increase in the amount of voltage coming from the power company
a sharp increase in voltage
A sudden series of pulses or spikes in the voltage or current of a circuit. The circuit is usually protected against power surges.
The amount of power flowing through your wires can vary considerably, and having it increase drastically and suddenly can cause damage to your computer's components. Most of this surge (or spike) is beyond your control, but, regardless of the cause, either computer user needs to install a device called a surge protector, between the computer and the wall. This offers full protection again power surges but offers no protection against other communicable diseases.
High voltage (above nominal 230/400 volts).
A very short lived increase in voltage and/or amperage. Also known as a power transient or spike. The surge can be induced into an electrical power line for a number of reasons including a lightning strike. Power surges can damage sensitive electronic equipment especially if left unprotected.
Power Surge was a DC Comics event in 2002 intended to promote the start of The Power Company, a new comic book series by writer Kurt Busiek, who also wrote all seven issues of Power Surge.
Power Surge is a high-impact thrill ride designed by Italian ride manufacturer Zamperla. The Power Surge was first operated in 1999, and is produced in both trailer-mounted and park versions.
