megaphone-redThis week, a fellow electrical engineer previously working in the industry (but since a couple of months more dedicated to academics/teaching) sent us an article.

His name is Pablo, and he wants to tell you his bad experiences concerning grounding.

Share your experiences too, send us a mail!

“Throughout my experience in housing construction as well as in the installation of raceways in existing buildings I have met with incorrect definitions concerning grounding with ground rods.

Among the myths that I have heard from technicians and customers I can mention:

Hello everybody, I am Steven Mill and at times I publish articles on the blog to feed this great community! Today, let me tell you about electric load forecasting…

Load forecasting is the predicting of electrical power required to meet the short term, medium term or long term demand. The forecasting helps the utility companies in their operation and management of the supply to their customers.

Electrical load forecasting is an important process that can increase the efficiency and revenues for the electrical generating and distribution companies. It helps them to plan on their capacity and operations in order to reliably supply all consumers with the required energy.

senior-electrical-engineeerIn an article published on March, our dear senior engineer Muhammad (20 years experience) amazed us with an article about the Thevenin’s Theorem. Indeed, he drew a great parallel with human beings and it was brillant!

Today he is back with another funny essay on this theorem. We don’t tell you more, just read and appreciate it:

New article from your fellow electrical engineer A.N. Do like him and send us your essays by mail.

The electrical load scheduling is the process of estimating the instantaneous loads operating in an installation. The load schedule provides the load for the particular installation in terms of apparent, reactive and active power (kVA, kVAR and kW) and usually carried out at the sub facility area or at the switchboard.

Using LED: global alert!

September 22nd, 2016 | 6 Comments | Posted in Energy Efficiency - lighting
Tags: , ,

Nowadays, saving energy is a major concern and the electricity area is no exception to the rule. As electrical engineers, you necessarily apply technologies or devices which aim to improve energy efficiency.

Among the front runners of these technologies stands the LED technology (Light Emitting Diode). It is indeed among the most significant progress of the last years; to the extent that LED lighting is about to become the global standard, coming after classic bulbs that soon won’t be sold by the manufacturers anymore. Notably intended for commercial and industrial buildings, and also for infrastructure (outdoor public lighting), its success lies in the fact that it produces a very efficient luminosity compared to conventional incandescent lamps.

Everybody seems to agree with the fact that LED technology is the future of lighting. However, several electrical installation professionals warned us with 2 major issues highly questioning its use.
