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.

Energy and Power
Insulating materials in electrical equipment
The reason for using insulating materials is to separate electrically the conducting parts of equipment from each other and from earthed components. Earthed components may include the mechanical casing or structure that is necessary to enable the equipment to be… Read more

How to locate underground faults on cable?
A common approach to test cable and determine insulation integrity is to use a Hi-pot test. In a hi-pot test, a DC voltage is applied for 5 to 15 min. IEEE-400 specifies that the hi-pot voltage for a 15-kV class… Read more

Typical Constructions Of Overhead Lines
Along streets, alleys, through woods, and in backyards, many of the distribution lines that feed customers are overhead structures. Because overhead lines are exposed to trees and animals, to wind and lightning, and to cars and kites, they are a… Read more

Solar Power
How solar collectors works?
Solar energy (solar radiation) is collected by the solar collector’s absorber plates. Selective coatings are often applied to the absorber plates to improve the overall collection efficiency. A thermal fluid absorbs the energy collected. There are several types of solar… Read more

What is the Static Var Compensator (SVC)?
Static Var Compensator is “a shunt-connected static Var generator or absorber whose output is adjusted to exchange capacitive or inductive current so as to maintain or control specific parameters of the electrical power system (typically bus voltage)”. SVC is based… Read more

Diagnosing Transformer Winding Insulation (video)
This video tutorial shows the progression of power factor or dissipation factor over frequency. Furthermore, measuring transformer winding insulation, including the connection of measuring leads, is explained. Reasons why recording frequency responses is important for a correct diagnosis of a… Read more

Ionization (Corona Discharge) Tests
The ionization test is used primarily for detecting ionization (corona discharge) and slot discharge in generator windings. Both ionization and slot discharge may cause deterioration of insulation. Ionization generally occurs in voids inside the insulation within the ground shield section… Read more

Understanding Transformer Polarity
With power or distribution transformers, polarity is important only if the need arises to parallel transformers to gain additional capacity or to hook up three single-phase transformers to make a three-phase bank. The way the connections are made affects angular… Read more

Want to live and use energy on Mars? Why not?
The problem of energy accessibility and production on Mars is one of the three main challenges for the upcoming colonisation of the red planet. The energetic potential on its turn is mainly dependent on the astrophysical characteristics of the planet…. Read more

GIS vs AIS – Substation Earthing
Compressed SF6 gas used in MV and HV switchgears as an insulating medium has led to the development of compact gas-insulated substation (CIS) technology (figure 1). GIS , having many advantages over often used and conventional air-insulated substations (AIS), have… Read more

Oil-Filled Equipment in Substation – IEEE 980-1994 (R2001)
A number of electrical apparatus installed in substations are filled with oil that provides the necessary insulation characteristics and assures their required performance. Electrical faults in this power equipment can produce arcing and excessive temperatures that may vaporize insulating oil,… Read more
