1754 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.

Renewable Energy
Fossil fuels are almost gone… Solar Energy? Hell Yes!!
Solar energy is not a finite resource as fossil fuels are. While the sun is up there it constantly produces all the energy we can use. While not maintenance free, what technology really is? Once solar panels, wind or water… Read more

Solar energy is free, but what does it really cost?
“Solar energy is free, but it’s not cheap” best sums up the major hurdle for the solar industry. There are no technical obstacles per se to developing solar energy systems, even at the utility megaWatt level (e.g., 14 MW utility… Read more

Discussing About LV And HV Electrical Cables
Space is really a critical criterion when discussing electrical cables and wires. In a low-voltage (LV) plastic-sheathed cable with conductor cross-sections of up to 10 mm2 per conductor or in high-voltage (HV) cables (Figure 2), the lion’s share of the… Read more

Purpose and maintenance of transformer bushings
The two most common types of bushings used on transformers as main lead entrances are solid porcelain bushings on smaller transformers and oil-filled condenser bushings on larger transformers. Solid porcelain bushings consist of high-grade porcelain cylinders that conductors pass through…. Read more

Internal losses that reduce efficiency of a DC generator
There are four internal losses that contribute to lower efficiency of a DC generator. Copper losses Eddy-current losses Hysteresis losses Mechanical losses Copper loss is the power lost as heat in the windings; it is caused by the flow of… Read more

Ceramic (Porcelain and Glass) Insulators
Porcelain is the most frequently used material for insulators. Insulators are made of wet, processed porcelain. The fundamental materials used are a mixture of feldspar (35%), china clay (28%), flint (25%), ball clay (10%), and talc (2%). The alternative method… Read more

Segregated Phase Bus System
In this construction all the phases are housed in one metallic enclosure as earlier, but with a metallic barrier between each phase, as illustrated in Figure 1. The metallic barriers provide the required magnetic shielding and isolate the busbars magnetically from each other, like an… Read more

How lightning really works? (video)
A lightning discharge develops in three stages: first, the collisions between ice particles and water droplets together with gravity separate positive and negative charges inside the thunder cloud and buildup a voltage. Then a discharge grows, forming a so-called streamer-leader… Read more

Synchronous Motor Construction
Synchronous motors convert electrical power to mechanical power and synchronous generators convert mechanical power to electrical power; and synchronous condensers supply only reactive power to stabilize system voltages. Synchronous motors, generators, and condensers perform similarly, except for a heavy cage winding on the… Read more

What Is The Potential Difference?
Potential difference is the term used to describe how large the electrostatic force is between two charged objects. If a charged body is placed between two objects with a potential difference, the charged body will try to move in one direction, depending upon the polarity of the object. If… Read more

Effective Resistance Of Busbars
The construction of busbar is usually carried out by putting together several flat bars in parallel for each phase. The spacing between the bars is made equal to their thickness for practical reasons, and this leads to skin and proximity effects. If one refers to… Read more
