Detection and prevention of faults in overhead electric lines is critical for the reliability and
availability of electricity supply. The disadvantages of conventional methods range from …

In zinc oxide (ZnO) surge arresters, leakage current usually flows across the arrester under
normal operating condition. Leakage current is one of the factors which contribute towards …

Multiple strokes are the main factors affecting the safe and stable operation of power
equipment. As the core lightning protection equipment, arresters are also frequently …

Lightning strokes on transmission lines could trigger insulation failure if no protective
measures are taken. Typically, a lightning arrester is used for this purpose. In order to …

The service continuity of the distribution electrical network faces challenges. Among these
challenges is the provision of protection against surge arrester failure, in which it is …

Surge arresters are usually used to protect distribution feeders against randomly distributed
lightning overvoltages. However, there is a probability of surge arrester failure due to an …

This paper presents a probabilistic evaluation of energy absorption capability of
transmission line surge arresters (SAs), based on Monte-Carlo method. In the presented …

This study introduces an arrangement of surge arrester, Rogowski coil, and triac to attain
service continuity of distribution networks. This new arrangement is proposed to limit the …

This study investigates the impact of the frequency-and current-dependent behavior of
concentrated tower grounding systems on the computed fast-front overvoltages across …

This paper presents a technical/economic comparison between remedial measures aimed
at improving the lightning performance of an existing Italian three-phase 150-kV overhead …
