New article by an electrical engineer from Venezuela. Thank you to all the experts who participate in this community! Enjoy and  don’t forget to leave a comment if you  want to share your thoughts on the electrical contactor.

Nowadays, there is an increasing need for users to take control of the comfort and safety systems installed in their area (air conditioner, lightning, and others) [1]. There are powerful reasons for this, the main one is the birth of a new trend, that goes back to the year 1999 [2], known as Building Automation Systems (BAS). This is related to the need of having control over systems by adding a special panelboard, like a PLC, a relay, a control panel, among others.

In this article, we will try to discuss the outlook of lightning protection inside the premises of an electrical substation… Enjoy and please comment below!

Lightning protection Introduction in context to part one

Lightning strikes are a natural phenomenon and high power surges regularly hit the vulnerable parts of earth’s crust. Electrical installations including the transmission lines and sub stations are quite vulnerable for lightning to strike due to the following reasons;

Last time, your fellow electrical engineer Pablo told you about his bad experiences concerning grounding. Now he wants to deal with the electrical installations topic and he got 3 questions for you at the end of the article!

There are many differences that I can mention I found among old residential electrical installations (50 years ago) and today’s installation. The energy needs have changed. The main point is the demand, although it is true that today families have greater economic capacity to acquire more electrical equipment is so quite true that the equipment efficiency has improved considerably.

In the following figures can be seen as the average energy consumption has decreased slightly in recent years:

Electrical Installation Guide 2015

Designer, Consultant, Contractor, Panel builder, Facility manager, Student, teacher, Standardisation or certification experts… we all have to know and comply to electrical installation standards and regulations, in order to ensure the safety (and more and more the energy efficiency) of our customers’ electrical installations.

These international standards, set by the IEC, are complex and keep evolving; as a result, we struggled to stay informed.

As an example, are you aware that the IEC 60364 “Low-voltage electrical installations” part 4-42 “Protection for safety – Protection against thermal effects” has been updated in 2014, and that in particular it now includes recommendations for arc fault protection?
