electrical-engineer-testimonyIn last month newsletter (newsletter#79), we introduced you to Mile, one of the members of the community.

From then on, he kindly decided to help providing the blog with material, and his 1st attempt is about power factor correction of networks.

Tell this young man from Macedonia what you think about it below!

The war between pro-AC fans and pro-DC fans has been around forever; ever since the end of the 19th century in fact.
Today, more than ever, the battle is raging! New technologies such as LED, cellphones, photovoltaic, and electric cars, are becoming more prevalent in our everyday lives, so it’s no surprise we’re witnessing a new major turning point in this AC versus DC battle: the pro-DC (electronic device manufacturer) fans are stepping up to the fight against the pro-AC (electric device manufacturers) who are carrying the flag for AC – which differentiates high and low current.

megaphone1Marvin M., one of the most active members of the Electrical Engineering Blog community chose to tell us about power grids.

Here’s his very interesting essay…

The introduction of distributed energy has had a significant impact on energy provision and management. The need to meet the consumer demand, as well as improving efficiency in the existing supply, has seen governments and power supply companies implement distributed generation, especially distributed renewable generation (DRG).

journal1Cables provide a pathway for electricity from the source to the end user, usually equipment or a tool.

Given the varied power requirements, it is crucial that the engineer selects the most appropriate type. This requires an innate knowledge of the factors that determine the current rating (ampacity).

The following highlights the primary considerations.
