If more voltage is introduced than an electrical appliance is designed to handle, this is called a power surge or transient voltage.

Snubber capacitors are designed for the high peak current operation required for protection against transient voltages.

Lightning and other high-energy transient voltage surges (upwards of 950 joules) and current surges (50,000A) can be suppressed with a whole house surge protector.

This basic principle explains the source of the destructive transient voltage in the Korndörfer motor starter apparatus.

Large power transformers are vulnerable to insulation failure due to transient voltages with high-frequency components, such as caused in switching or by lightning.

A power surge, or transient voltage, is an increase in voltage significantly above the designated level in a flow of electricity.

Also known as transient voltage, surges are any increases above the standard power voltage for a given electrical line.

As an example, a hydraulic load cell is immune to transient voltages (lightning) so might be a more effective device in outdoor environments.

A preselector also protects the sensitive receiver input from damage caused by static and voltage transient.

In all systems, a soft start limits the inrush current and so improves stability of the power supply and reduces transient voltage drops that may affect other loads.
