How to guard utility personnel from shock hazards

BY JEFF JOWETT, Megger

In the power industry, safety is just as important a function as performance. Safety considerations, parameters, and methods of implementation are an integral part of any electrical system. A most important element is the grounding system. This system performs several functions, not the least of which is safety. Substations are active in fault clearance, and personnel working in and around them, as well as pedestrians passing in the vicinity, need to be protected. When a fault condition occurs, the grounding electrode (grid) must be sufficient to equalize potentials...

The rapid shift toward renewable energy resources (RERs) has placed significant demands on traditional power systems. To address these challenges, modern energy infrastructure is evolving into smart grids, leveraging advanced technologies like Virtual Power Plants (VPPs) to enhance grid flexibility, reliability, and efficiency. A VPP is a collection of distributed energy resources (DERs), such as renewable energy sources, battery storage, controllable loads, and electric vehicles (EVs), that operate as a unified power plant through intelligent control and communication networks. By integrating VPPs with smart grids, the energy sector can better coordinate energy generation, storage, and consumption, facilitating a more resilient...
