Our surge arresters are absolutely reliable and characterized by easy installation, low maintenance costs and an extremely long operating life The final step in the protection plan is to install 'point of use' surge suppression devices. Often you will see these called 'transient voltage surge suppressors'. These are your last line of defense. They are capable of only stopping the leftover voltage surge which got past the grounding system and the lightning arrester Secondary Lightning Arrestor. In areas with a moderate or high frequency of lightning strikes, or where the consequences of lightning damages are high, a second in-line lightning arrestor should be used. This is typically installed where the cabling enters the building. This lightning arrestor must also be connected to the lightning earth system
the arrester. Surge arresters are devices that help prevent damage to apparatus due to high voltages. The arrester provides a low-impedance path to ground for the current from a lightning strike or transient voltage and then restores to a normal operating conditions.

In telegraphy and telephony, a lightning arrester is a device placed where wires enter a structure, in order to prevent. the surge arrester is surge voltage (e e) and the reflected voltage is zero (e' 0). When a surge arrives at the arrester, and the arrester starts conducting, its impedance is ideally zero as shown in Figure 4 (c). The voltage across the surge arrester is zero (e 0) and the reflected voltage is the opposite of the of surge voltage (e' e) A lightning arrester installed in an electrical power system is designed to protect some electrical equipment against damage due to lightning impulse strike. However, if there is a multiple impulse current striking a lightning arrester, it may damage the lightning arrester itself and then, as a result, it cannot.
