Testimonial by Mile, an electrical engineer from Bitola. He’s already shared feedbacks of his electrical projects with us and it’s always a pleasure to read his writings. Let’s read about electrical current and the wear out phenomenon.

The phenomenon called wear out potential is caused by the current that flows when single-phase earth fault occurs.  The analysis of the current flowing during earth fault in the network, could be easily done with α, β, 0 components of the voltage and the current by using Laples’s transformation and complex amplitudes.

Synchronous Generator or Alternators is one of those inventions which had changed the face of the world. It has allowed us to make use of mechanical energy into electrical energy making life simpler.

Furthermore this electrical power is used for various conveniences in Industries, Educational Institutes, Transportation, Shopping Malls etc. Let’s read what Engineer B.B has to say about Paralleling of Generators and Synchronization.

Basic Construction of underground cables

This article is the next and last part of Khuram’s article on underground MV/LV distribution systems. Enjoy and comment BELOW if you have any questions.

Underground electrical distribution is not only tidier but also less prone to environmental hazards as compared to the overhead distribution. Installation and maintenance cost, operational pros and cons, and a brief overview of cable structure are discussed in the previous part. Distribution transformers, switchgear and MV/LV cables are the main components of underground distribution system.

Structure and types of underground cables for a distribution system are discussed in this article.

New article by an electrical engineer from Venezuela. Thank you to all the experts who participate in this community! Enjoy and  don’t forget to leave a comment if you  want to share your thoughts on the electrical contactor.

Nowadays, there is an increasing need for users to take control of the comfort and safety systems installed in their area (air conditioner, lightning, and others) [1]. There are powerful reasons for this, the main one is the birth of a new trend, that goes back to the year 1999 [2], known as Building Automation Systems (BAS). This is related to the need of having control over systems by adding a special panelboard, like a PLC, a relay, a control panel, among others.
