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.

megaphone-blueHi everyone it’s Steven Mill. It’s been a while but I’m back with an article for my dear community. Today I want to deal with a basic: “how to specify dry type transformer”. Hope it will help some of you.

If you wonder how I get my articles published, well it’s easy as ABC cause I just propose an article by mail to the moderator team and after a quick review, they publish it :) So do not hesitate. The more the merrier!

Introduction

Generally, specifying dry type transformer is same as specifying oil transformer. Yet, as dry type transformer is usually used in indoor and when apparent risk exist, there are some specifications we should consider.

New interesting article by Mile who wanted to tell us about an experiment he did with replacing the excitation system of turbogenerator type ТВВ-200-2А with thirystor based excitation system.

You wonder what he found, right? Then check his article now:

Introduction

The excitation system of great sources of electric power is one of the most important factors in every power system. In REK Bitola, the turbogenerators are equipped with excitation system with high frequency AC excitatory and automatic voltage regulator made of magnetic amplifiers. The excitation system gives the necessary current to the rotor of the generator in all modes of work.

megaphone-yellowOne of our members kindly sent us an article in which he’s willing to explain how the energy is used in a fctory or in a building. Really interesting!

If you too want to send us essays or even debates, tutorials, career stories, testimonies from something you’ve experienced, simply send a mail to the team.

Introduction

Saving on electrical energy costs is the goal of every consumer, whether commercial or individual. This has many benefits such as letting companies reduce their production and operation costs and hence remain competitive. In addition, less energy usage means improved efficiency and less damage to the environment.
