Everything about Overvoltage

When voltage across/within a circuit is raised beyond the design limit

In electrical engineering, overvoltage is the raising of voltage beyond the design limit of a circuit or circuit element. The conditions may be hazardous. Depending on its duration, the overvoltage event can be transient—a short (milliseconds) voltage spike—or sustained with a stable value on multiple terminals. In an electrical grid, voltage control and reactive power management are inseparable facets of a single activity. Wikipedia →

📖 Definitions

Noun The difference between the electric potential of an electrode or cell under the passage of a current and the thermodynamic value of the electrode or cell potential in the absence of electrolysis.

Noun The hazardous condition that occurs when the voltage in a circuit is raised above that for which it was designed.

Verb To raise the voltage of a circuit beyond that for which it was designed.
