megaphone-darkblueLight 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.


Types of Partial Discharges on gases

August 9th, 2018 | Make a comment | Posted in Electrical distribution

megaphone-bluePartial discharges (PD) are intermittent low intensity electric arcs which are not visible and that take place inside electrical equipments.

Let Carlos (a consultant for a company developing solar PV system installations) tell you more about this topic.

Partial discharges produce damage that on the long term can end up in electrical failure, which is why it is convenient to establish preventive maintenance in order to consider replacement at proper time before the electrical failure takes place.

New article sent by one of our beloved visitors and member Yasser. This time, he chose to share an overview of Power Transmission Systems at MV and LV levels

If you too want to share writings with everybody, please send us a mail.


Electrical power passes by many stages before it reaches our homes. The power generated at the utility can’t be directly to consumers due to many technical aspects such as:

MV busbar schemes (Review)

March 5th, 2018 | 1 Comment | Posted in Electrical distribution

megaphone-blueChoosing a good bus scheme is vital for operational reliability, safety and redundancy of power supply system.

Your fellow electrical engineer K. tries to discuss busbar layout and busbar schemes as per the design of a typical substation.


Busbar(s) consist of incoming and outgoing circuits with a common point. Every circuit connected to a busbar scheme has its separate incomer, circuit breaker, isolator, potential transformer, current ratio transformer and associated switchgear. These components are arranged in a special sequence so as to trip a specific circuit in case of an abnormality.
