Circuit Breaker Selection Tips

November 9th, 2018 | Make a comment | Posted in Electrical Safety

Today we are going to talk about a very essential and popular item in every electrical system. Its importance spreads over power plants, houses and small apartments.

We can’t deliver electricity to any load without it; a circuit breaker. Therefore, Yasser one of the member of our community blog sent us this guide in which he hits some points regarding it. Enjoy!

Read this nice article about the importance of thermography in predictive maintenance of electrical systems (Medium Voltage/Low Voltage).
It is written by one of the member of this community and we think you’ll enjoy the thermal point of view of his essay.

If you’d like to write your own article too, we can publish :) it simply send us a mail.

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.

Steps of Installing an Earthing System

August 13th, 2018 | 1 Comment | Posted in Electrical Safety

Hello everybody, I’m Yasser, I am electrical engineer and I often publish in this blog. In one of my articles I said “As only few mille amperes can kill a human in a part of second, safety always is the big concern for electrical engineers and protection systems designing gets much more attention”.

Therefore we are going to continue talking about safety in many articles and this time it is earthing turn.
