Light is so essential in our live, we can’t live without. Light affects everything on earth including plants, animals and also humans. We need light to grow plants, generate electricity (solar energy), for medical uses and for our living (in home, work & etc…) which is called lighting.

In the following paragraphs Yasser an electrical engineer who published few articles in this blog is talking about lighting design considerations and giving guidance for you to facilitate the lighting design process.

My name is Mile and here’s my article about my work on the following huge electrical engineering project. Enjoy :)

The production capacity of REK Bitola, the biggest power plant in Republic of Macedonia, is around 80% of all the consumed electric power in Macedonia. Regarding that fact, the Suvodol and Brod Gneotino mines, are the vital points from where the plant receives coal, in table 1 I have presented the measured installed power of the both mines and their power blocks.

Table 1. Installed power

5 Reasons why you should introduce Children to Electrical Engineering

September 4th, 2018 | Make a comment | Posted in Others

Electrical engineers, if you had any how was your holidays? Usually children are back to school on September, that’s why we thought it was a ncie idea to publish an article about children and Electrical Engineering.

If you’re a parent and looking for an alternative to regular educational toys for your child, this article is for you.

Most probably, if you are an electrical engineer, you know what MCC stands for. So let’s briefly introduce it to those who are not experienced in this field.

MCC stands for “Motor Control Center” and as you can grasp from its name that it is used to control motors in the industrial or even commercial applications where many motors are to be controlled.

The questions now are why do we use MCCs? And what are the components?

Installing lightning protection system for your facility in 3 Steps (Surge Protection)

August 20th, 2018 | Make a comment | Posted in Electrical Safety

Hello fellows electrical engineers it’s Steven Mill! Let’s get straight to the point; Do you know what will happen if frictions happened between air streams and the humidity in a cloud? I’ll tell you. A huge amount of negative static charges are formed in the lower side of the cloud while as the positive charges are formed in the upper side of the cloud.

Moreover, the buildings have positive charges. Which means there is a voltage difference between the clouds and buildings.

What if this voltage increased till it’s more than 30 KV/cm (the amount needed to break the isolation of air)? Air will be broken down and the charges will be released in a spark to the buildings. Which is known as lightning.
