1750 awesome technical articles
Hi, I'm an electrical engineer, programmer and founder of EEP - Electrical Engineering Portal. I worked twelve years at Schneider Electric in the position of technical support for low- and medium-voltage projects and the design of busbar trunking systems.
I'm highly specialized in the design of LV/MV switchgear and low-voltage, high-power busbar trunking (<6300A) in substations, commercial buildings and industry facilities. I'm also a professional in AutoCAD programming.

Heat vs. Current in a Resistor
It is converted from one form to another. One of the most familiar forms of energy is heat. When a current (I) is forced through a resistor (R) by applying a potential (V), the electrical energy is converted to heat… Read more

What Is a Good Ground Resistance Value?
The goal in ground resistance (or earth resistance) is to achieve the lowest ground resistance value possible, that makes sense economically and physically, when contacting the earth, also known as the soil/ground rod interface. Ideally, a ground should be zero… Read more

Why Community Acceptance Is Important for Planning, Design and Construction of Substation?
Community acceptance generally encompasses the planning, design, and construction phases of a substation as well as the in-service operation of the substation. It takes into account those issues that could influence a community’s willingness to accept building a substation at… Read more

Five special transformers for industrial applications you should know about
A number of industry applications require specific industrial transformers due to the usage of power (current) as a major resource for production. Electric arc furnaces (EAF), ladle furnaces (LF) and high-current rectifiers need a specific design to supply the necessary… Read more

An Overview Of Control (Ice Cube) Relays
An electromechanical relay is an electrical switch actuated by an electromagnet coil. As switching devices, they exhibit simple “on” and “off” behavior with no intermediate states. The electronic schematic symbol for a simple single-pole, single-throw (SPST) relay is shown here:… Read more

Determining the soil resistivity to design a good substation grounding system
It is essential to determine the soil resistivity and maximum grid currents to design a substation grounding system. The touch and step voltages are directly proportional to these values. Overly conservative values of soil resistivity and grid current will increase… Read more
