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.

AC Interference in Shared Corridors
Increasingly, the electric power industry finds the need for rights-of-way that are either co-located or that cross other conductive facilities such as pipelines or railroads. High voltage AC transmission lines may affect adjacent facilities, which can possibly damage equipment, reduce the facilities longevity, and create hazards for the personnel and public. This webinar, given by David Lewis, P.E., an electrical engineer at EasyPower, explains how nearby facilities are affected by AC interference and provides guidance in the steps that engineers can take to accurately evaluate the complex challenges of AC interference using XGSA_FD. ...

Understanding NESC 5 mA Let-Go Shock Hazard
An advantage of using the alternating current in power systems around the world is the ability to transform voltage to transfer more energy farther with greater efficiency. The bulk electric grid consists of multiple high voltage transmission lines that provide power to substations where the voltages are reduced to distribution levels through a transformer. The electromagnetic fields (EMF) that allow the transformers to bring high voltage to distributions voltage levels are present throughout the whole of the line and may produce hazards on nearby recipient metallic objects.
Transmission Line Electromagnetic Fields
As illustrated, an individual may make contact with a capacitively energized truck, providing a path to ground through their hand and body. Depending on the magnitude of capacitive coupling, this current is perceptible... Read the full article
