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 …

The installation of a corona ring on an insulator string on a transmission line is one of the
solutions to reduce the electric field stress surrounding the energised end of the insulator …

Purpose The purpose of this paper is to propose an optimum design of a corona ring for
insulator strings using optimisation techniques, which are gravitational search algorithm …

High structures are frequently hit by lightning and one of them is a wind turbine. The receiver
has a major role to play in ensuring the lightning strike protection performance on wind …

A surge arrester diverts lightning surge to earth, preventing damage on electrical systems.
Under normal operating condition, surge arresters do not conduct current but there is a …

Lightning is a kind of electromagnetic phenomena that occurs frequently in nature. It poses a
greater threat to the safety of human beings, facilities and structures on the ground. In severe …

This paper investigates the voltage breakdown characteristics of three types of lightning rods-
blunt, sharp and flat. The objectives of this study are to determine the voltage breakdown …

If the receivers on the wind turbine blade do not manage to block the lightning, the blade or
the wind turbine (WT) may be destroyed. So the receiver plays a key part in identifying the …
