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.

Ethernet History
Ethernet is the most popular and widely deployed network technology in the world. In 1973, while working on a way to link the Xerox “Alto” computer to a printer, Bob Metcalfe designed and tested the first Ethernet network. This first… Read more

Geothermal Energy
Geothermal Energy – The Hot Facts
The word “geothermal” comes from the Greek words geo (earth) and thermal (heat). It means the heat of earth. The energy potential beneath our feet, in the form of geothermal energy, is vast. This tremendous resource amounts to 50,000 times… Read more

How Do I Choose the Best Site for My Wind Turbine?
You can have varied wind resources within the same property. In addition to measuring or finding out about the annual wind speeds, you need to know about the prevailing directions of the wind at your site. If you live in… Read more

High Voltage
Transients – Line Disturbances
Lightning strikes and switching transients on power lines will propagate down the line and eventually arrive at a substation. There, the voltage will be clamped by lightning arresters to a level the substation equipment can handle without damage. This voltage… Read more

Can I Connect Wind Turbine to the Utility Grid?
Small wind energy systems can be connected to the electricity distribution system and are called gridconnected systems. A grid-connected wind turbine can reduce your consumption of utility-supplied electricity for lighting, appliances, and electric heat. If the turbine cannot deliver the… Read more

Substation Ventilation Requirements – Ergon
Substations require special attention to ventilation in order to dissipate heat losses from electrical equipment. Wherever possible, natural air flow to the outside of the building will be used. Forced ventilation should be used where natural ventilation is not practicable…. Read more

Is There Enough Wind on My Site?
Does the wind blow hard and consistently enough at my site to make a small wind turbine system economically worthwhile? That is a key question and not always easily answered. The wind resource can vary significantly over an area of… Read more

What Do Wind Systems Cost?
A small turbine can cost anywhere from $3,000 to $35,000 installed, depending on size, application, and service agreements with the manufacturer. (The American Wind Energy Association [AWEA] says a typical home wind system costs approximately $32,000 (10 kW); a comparable… Read more

What Are Partial Discharges On Cast Resin Transformers?
Partial discharges are electrical discharges occuring in insulating materials. The electrical discharge’s path only spans part of the insulating distance separating the conductors. The problem of partial discharges, whilst not existing in Low Voltage, is found in High and Very… Read more

Oxidation Of Conductors
High-resistance oxides form very quickly on aluminum and copper conductors expose to air. Once the oxides are stabilized, they prevent further oxidation of the parent metal; however, due to this high electrical resistance, these oxides must be broken or removed… Read more

Security for Substation Communications
Until recently the term “security,” when applied to SCADA communication systems, meant only the process of ensuring message integrity in the face of electrical noise and other disturbances to the communications. But, in fact, “security” also has a much broader… Read more
