Surge protection devices are particularly used for electric networks, telephone networks, and other communication buses. The surge protection device offered by the surge protection device manufacturers
is the component that’s used for electrical installation program system. This device is connected in the parallel position of the power supply circuit that’s used for delivering power supply to all the directions of a network. This is the most used and efficient type of overvoltage protection.
Surge protection devices by the surge protection device manufacturers are designed to limit the overvoltage of atmospheric origin by limiting the amplitude that’s not hazardous for the electric installation, switchgear, and control gear. Surge protection device reduces the over voltages:
- In common mode, it’s neutral on earth.
- In differential mode, between phase and neutral. If the overvoltage is exceeding to the expected threshold, the surge protection device
- In common mode, it conducts the energy to earth.
- In differential mode – distributes the energy to other conductors. The three types of surge production devices:
Type 1 – It is usually used on industrial buildings and service sectors. This is protected by a protection system and cage. This protects the installations against lighting strokes.
Type 2 – This is the main protection system that deals with low voltage electrical instruments. This way the overvoltage is prevented from spreading and protects the loads effectively.
Type 3 – This has an exceedingly low discharge capacity. This is mostly beneficial for sensitive loads.
