Gandian Electric Tells You The Cause Of The Surge

- Dec 02, 2019-

A surge is also called a surge, which is an instantaneous overvoltage that exceeds the normal voltage. In essence, a surge is a violent pulse that occurs in just a million seconds. Surge sources of the power supply system are divided into external (cause of lightning) and internal (electrical equipment operating overvoltage).

The lightning discharge between the surge cloud layer and the ground caused by lightning is composed of one or several separate lightning bolts. Each lightning bolt carries a current with a high dry amplitude and a short duration. One type of lightning discharge will include two There are two or three flashes, and each lightning is separated by about one-twentieth of a second. Most lightning currents are as high as tens or even thousands of amps, which will cause huge electromagnetic and mechanical effects.
