A lightning strike could bring thousands mega-ampere of current in a blink of eyes. As a
result, a failure of grounding the strike may cause serious damage to the home and …

Transmission line parameters are usually calculated based on technical and environmental
approximations, eg line height, cable conductivity, etc. These characteristics vary depending …

This paper introduces an optimized numerical analysis approach to calculate the number of
direct lightning strokes to tall towers. In the conventional numerical method, the lightning …

At present, the precise location of fault tower struck by lightning still relies on manual line
inspection, the search process is time-consuming and laborious. This paper proposes a …

Transmission tower grounding safety is a critical element that significantly impacts the
reliability and sustainability of power grids. Tower grounding resistance is a significant …

Electromagnetic transients are responsible for overvoltages and overcurrents that can have
a negative impact on the insulating elements of the electrical transmission system. In order …

Leakage current and temperature are common features of zinc oxide (ZnO) arrester
degradation in power systems; however, for substation engineers, these key features often …

The authors present a methodology to improve the rational modelling of non‐uniform lines
(NuLs). First, they formulate a segmented chain matrix representation of the NuL, which is …

This paper presents a study of sensitivity of the equivalent circuit of ZnO surge arresters
based on the model proposed by the IEEE. The main contribution of the proposed paper …

An analysis of analytic tower models is proposed for simulation of electromagnetic transients
in transmission lines supported by towers up to 300 m height. A careful analysis is required …
