transient voltage

A transient voltage is a short, sudden spike or surge in electrical voltage within a circuit. It can be caused by events like lightning strikes, switching of electrical equipment, or power fluctuations. These brief voltage increases can potentially damage electronic components or disrupt equipment operation. Transient voltages typically last just a few microseconds to milliseconds and are different from normal, steady voltages, which remain consistent over time. Proper protection devices, like surge protectors, are used to shield electrical systems from these sudden bursts and ensure safe, reliable operation.
