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.

Photovoltaic Module Interconnections
Copper conductors are recommended for almost all photovoltaic system wiring. Copper conductors have lower voltage drops and better resistance to corrosion than other types of comparably sized conductor materials. Aluminum or copper-clad aluminum wires can be used in certain applications,… Read more

AC Vs. DC
What’s this thing about AC anyway? A little history lesson might be in order. It all started when Edison built the first incandescent bulb and the power station to light it. A big disadvantage of DC electricity immediately revealed itself:… Read more

Risk and Consequences Of Transformer Fire
The risk of a catastrophic fire with a properly inspected, tested, and maintained transformer is small. Proper maintenance and thorough testing of the transformer will prevent or detect many events that could lead to explosion and/or fire. However, unforeseen events… Read more

Electrically Held Contactors – Siemens
Most lighting and heating applications require a contactor to control the loads. One type of contactor is an electrically held contactor, which is similar to a magnetic starter. Unlike a magnetic starter, however, a lighting and heating contactor is designed… Read more

The Advantages Of Maintaining A High Power Factor
A high power factor eliminates penalty dollars imposed when operating with a low power factor. For many years, most utilities demanded a minimum of 85% power factor as an average for each monthly billing. Now many of these same utilities… Read more

Operating Principle Of Three Phase Asynchronous Motors
The operating principle of an asynchronous motor involves creating an induced current in a conductor when the latter cuts off the lines of force in a magnetic field, hence the name “induction motor”. The combined action of the induced current… Read more

How To Connect Current Transformers?
The primary of a current transformer typically has only one turn. This is not really a turn or wrap around the core but just a conductor or bus going through the “window.” The primary never has more than a very… Read more
