Electrical Grounding and Related Topics

A grounding system analysis or study is the evaluation of the grounding system in meeting its design objectives. In the power industry, the primary focus is addressing the aspect of personnel and public safety. IEEE Std 80 provides guidance for safety related to grounding in AC substations. This standard highlights the dangerous conditions that may occur during a ground fault that can severely or fatally injure individuals in the area or in contact with metallic objects.

Save Time with Rolling Sphere Lightning Protection Designs

The Rolling Sphere Method (RSM) is a methodology that is used to calculate lightning protection of exposed structures. RSM calculates the amount of exposed structure, its distance from the point at which lightning strikes ... Watch Video


Lightning Protection Systems

Lightning is a spectacular display of electrical forces in nature and easily recognized by the general public to be potentially hazardous. The detailed work engineers provide to design lightning safety for facilities and various structures may not be as easily recognized. The purpose of this article is to promote knowledge related to lightning protection and the study of a lightning protection systems (LPS). In this article we illustrate XGSLab SHIELD module’s processes for evaluating an LPS.

Lightning Background

Within a cloud, electrostatic charge formation occurs resulting in electric fields that affects the electrical gradients of the Earth’s surface. Hundreds of kV per meter produce step leaders typically ... Read the full article
