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;

Lightning strokes are nature’s crude way of disposing-off excess frictional energy dissipation among clouds. Arcs ranging up to thousands of volts break the insulation of air and strike the highest and vulnerable points on ground.

If not controlled and provided an alternative path, these surges can destroy almost any structure that comes between their paths to the ground. Read this article by Kam, an electrical engineer who sent us this essay by email.

Safety basics and risks avoidance

November 19th, 2018 | Make a comment | Posted in Electrical Safety

Radical energies and complex mechanisms are used and implemented in all industrial processes nowadays. Such processes can potentially cause serious harm to personnel or property during an accident. In such a scenario, absolute safety is not achievable, reduction of risks to acceptable level is possible.

Let’s read what your fellow electrical engineer Yasser has to say about it.

New article by one of you who sent us his essay via email. Enjoy and let us know what you think in the comments.

Introduction to RTV polymeric coatings

Hydrophobic insulators are quite a requirement in the areas along coastal belts. Increased salt concentrations in the atmosphere damage the insulators in many ways. Elevated humidity also escalates this problem and a hydro-resistant surface coating is always an economical solution to this problem.
