They differ only in constructional details but operate on the same principle, providing low resistance path for the surges to the round The online monitoring of arresters uses the grounding current of the lightning arrester as the power for a sampling device [18]. The magnitude of the leakage current is converted into the change of optical pulse frequency, and a series of high-tech means, such as fiber sampling, microcomputer data processing, and data communication, are adopted

A lightning arrester is a device used on electric power systems and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. 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.
