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.

Safety
How Do We Define Hazardous Areas?
The first requirement is to know what a hazardous area is. The principal factors relevant to the classifications of a hazardous area are the nature of the gases or dust present in the potentially explosive atmosphere and the likelihood of… Read more

Electric Motor
How Motor Really Works?
The basic working of a motor is based on the fact that when ‘a current carrying conductor is placed in a magnetic field, it experiences a force’. If you take a simple DC motor, it has a current-carrying coil supported… Read more

Did Tesla Discover the Secrets of Antigravity?
Nikola Tesla has been credited for the creation of much of the technology that we take for granted today. Without the genius of Tesla we would not have: Radio, Television, AC electricity, Tesla coil, Flourescent lighting, Neon lighting, Radio control… Read more

Wind Power
How to Monitor Wind Speed?
When considering wind power, most people ask what the average annual wind speed is and how to get that number. The usual response is that you must monitor the wind speed at your site for at least 12 months, preferably… Read more

Transformers
What is transformer rating based on?
In the U.S., transformers are rated based on the power output they are capable of delivering continuously at a specified rated voltage and frequency under “usual” operating conditions without exceeding prescribed internal temperature limitations. Insulation is known to deteriorate with… Read more

How to manipulate energized conductors with hot stick
Hot sticks are poles made of an insulating material. They have tools and/or fittings on the ends which allow workers to manipulate energized conductors and equipment from a safe distance. Hot sticks vary in length depending on the voltage level… Read more

Power measurement in a three-phase system
Electrical power is measured with a wattmeter. A wattmeter consists of a current coil connected in series with load, while the other potential coil is connected parallel with load. Depending on the strength of each magnetic field movement, the pointer… Read more

Underground residential distribution layouts
Where general appearance, economics, congestion, or maintenance conditions make overhead construction inadvisable, underground construction is specified. While overhead lines have been ordinarily considered to be less expensive and easier to maintain, developments in underground cables and construction practices have narrowed… Read more

Purpose of Disconnect Switches In HV Substation
Switches may be of several types, the common characteristic is that none are designed to interrupt fault currents and the insulation or insulators associated with them must coordinate with the rest of the system and a BIL (Basic insulation level)… Read more

Discrimination between residual current circuit breakers (RCCBs)
The operating principle of the residual current release is basically the detection of an earth fault current, by means of a toroid transformer which embraces all the live conductors, included the neutral if distributed. In absence of an earth fault,… Read more

Environmental Stresses On External Insulation
The external insulation (transmission line or substation) is exposed to electrical, mechanical, and environmental stresses. The applied voltage of an operating power system produces electrical stresses. The weather and the surroundings (industry, rural dust, oceans, etc.) produce additional environmental stresses….
