Using LED: global alert!
As electrical engineers, you necessarily apply technologies or devices which aim to improve energy efficiency. Among the front runners of these technologies stands the LED technology (Light Emitting Diode) which is about to become the global standard, coming after classic bulbs that soon won't be sold by the manufacturers anymore.
Everybody seems to agree with the fact that LED technology is the future of lighting. However, several electrical installation professionals warned us with 2 major issues highly questioning its use.

DC: danger alert?
1. Watch the video in this blog post that shows the impact of the "zero crossing" of the voltage, every 10 milliseconds by the sine wave in the AC distribution 2.Tell us what you think.
Could full-DC really be dangerous? Are you rather pro-AC or pro-DC and why? What is the most viable solution? The most environmentally friendly? More generally, what's your opinion on the War of Currents?

Types of electrical joints and terminations (back to basics)
Electrical joints and terminations provide the required electrical connection as well as the mechanical support, and physical protection of the cable. There are different types of joints and terminations based on the function, type of cable and construction materials.
Electrical Cable jointing procedures
Joining electrical power cables can be as simple as twisting the wires and taping them or more detailed using a variety of inline adapters and connectors. The method used for a particular joint depends on the voltage, type of cable, type of joint, type of connector, application and other factors. Regardless of the method used, it is important to have the proper tools and materials.
Click to read about some of the key factors that ensure clean, safe and reliable connections.
Reverse power relay basics and operation
The reverse power relay is a directional protective relay that prevents power from flowing in the reverse direction. The relay is used in installations where a generator runs in parallel with the utility or another generator so as to prevent power from the bus bar or another generator from flowing back to the active generator when its output fails.
Underground cables: types, advantages & disadvantages
Underground cables are used for power applications where it is impractical, difficult, or dangerous to use the overhead lines. They are widely used in densely populated urban areas, in factories, and even to supply power from the overhead posts to the consumer premises. They have several advantages, yet, they also have disadvantages. Read more to find out which ones.
