The surge arrester is a tool that can be mounted inside the electrical panel, thus upstream of the house system. Its use allows the electrical system on which it is installed to be protected.
The surge arrester will protect the entire system from surges, surges and spikes of electricity that may come from the power line operator, or from atmospheric phenomena such as lightning. These power anomalies can cause serious damage to devices connected to outlets.
An electricity surge can cause a pc hardware to break, or short circuit the boards of smartphones, tablets, and home appliances. In the event that the flow of energy suddenly increases dramatically, human life may even be in danger due to electrocution.
To prevent this from happening, it is therefore advisable to install a surge arrester.
Surge arresters are divided into three classes:
In class 1 we find devices to be used in areas where adverse weather phenomena such as thunderstorms and lightning usually insist (for example, in mountains). In this case the arrester is mounted in the electrical panel and can withstand several surges without being damaged. Discharge occurs in 350 microseconds, so excess energy does not reach the system.
In class 2 are surge arresters that protect the system from surges and spikes that may be caused by maintenance work on the line by the operator.
In class 3, on the other hand, we find those devices that offer even greater protection: in this case, the surge arrester is installed directly at the electrical outlets in the home.
