The correct operation of surge arresters under lightning and switching transient conditions
requires that grounding be effective at high frequencies as well as at power system …

This paper aims to present a novel proposed formula, along with technical viewpoints, to
solve the problem of transmission lines outage rate due to back-flashover phenomena in …

This article addresses the critical need to reduce grounding impedance for the protection of
both individuals and electrical equipment under normal and faulty conditions. While …

Different configurations of counterpoises are often used to reduce the resistance and
impulse impedance of the transmission line grounding. However, there are no general rules …

Although the underlying phenomena when grounding electrodes discharge lightning
currents are very complex, it is possible to derive simple formulas of impulse characteristics …

The effective length of the ground electrode is one of the primary research interests of
lightning grounding system design. In this article, using a practical numerical analysis, a new …

Human safety is the most important factor to determine any grounding system, therefore low‐
frequency grounding resistance (LFGR) of wind power generation systems should be very …

As the simple grounding electrodes alone may not provide the required low impedance
beyond the effective length, a new electrode configuration of optimum impedance is …

Reducing the grounding resistance using low resistivity materials (LRM) is a widely used
technique to improve the grounding system performance, especially under high resistivity …

This paper aims to study and analyse the behaviour of ground electrodes at low and high
frequency ranges. Single-layer soil is considered where several values of soil resistivity are …
