electrical installation fireWhat happens when a MV AutoTransformer misconnection and a LV breaker hooked up to an inadequate wire size meet? FIRE! Here’s a story that D.Ros, an electrical engineer based in Germany, kindly sent us. Read below the details on the day his electrical installation caught fire.

Enjoy and please note that the aim is not to denounce but to understand better the situation so that you all can be careful in the future during your own electrical projects.


Hi I’m D. and today I wanted to share a story with you all. The day when my electrical equipment burnt!

megaphone-yellowNo one among us could consider a life without electricity. From social media to the entertainment industry and from the healthcare to educational institutions – its electricity alone that is powering wonders for us.

However, we seldom pay attentional to the health and integrity of our domestic electrical systems. The situation is much better at the commercial level and industries as they usually operate with dedicated manpower and resources for taking a good care of their LV, MV or HV electrical distribution system.

That’s the topic that your fellow electrical engineer B.Q. chose to tell you about today. Enjoy and comment!

9 best recommended grounding practices for safety and power quality

grounding practices for safety and power quality 1

Grounding is the most important factor that governs the safety and the quality of a power system.

That’s on what Steven Mill wants to write today. Will you agree with his guidelines for safety and power quality?

“Grounding, also known as earthing, provides a safe way for the fault currents to pass on to the ground (neutral). This avoids sudden voltage spikes in the distributed network system, safeguarding the electrical equipment from permanent or premature failure. Grounding systems are generally designed keeping low-impedance paths in mind.

When a fault occurs, a low-impedance current flow path can result in discharging high volumes of current into the ground pretty quickly, keeping the equipment safe. Grounding also plays a vital role in transferring transients caused due to lightning strikes into the ground safely and quickly.”

Following are the recommended grounding practices according to me and maybe to you all:

Hi this is Steven Mill and today I want to tell you about my experience as an electrical engineer. That’s why I wrote this article which gathers 10 safety precautions you should take when you work on LV equipement.

electrical safety precautions

I have put together this article with an intention of providing some safety precautions to all those electricians and electrical engineers out there, who work on low voltage equipment regularly. Irrespective of the kind of experience you have in this field, I strongly suggest you to stay alert even when you are repairing the minutest of the faults, especially, when the electrical equipment is live.

Being an electrical engineer and having served in this field for over 10 years, I strongly recommend you to follow the below mentioned ten most important safety precautions that can help you keep away from electrical hazards.
