Testimonial by Mile, an electrical engineer from Bitola. He’s already shared feedbacks of his electrical projects with us and it’s always a pleasure to read his writings. Let’s read about electrical current and the wear out phenomenon.

The phenomenon called wear out potential is caused by the current that flows when single-phase earth fault occurs.  The analysis of the current flowing during earth fault in the network, could be easily done with α, β, 0 components of the voltage and the current by using Laples’s transformation and complex amplitudes.

megaphone-yellowMile is one of the community members. He’s a young electrical engineer from Macedonia who likes to share is experience.

Let’s read his essay on grounding systems, based on what he’s experienced in his recent career.

And if you want to share your experience as a young electrical engineer, do not hesitate to contact us.

It is very well known, that in case of short circuit in the power system, the current that appears on the place of the short circuit, is directly transferred to the earth.

The value of the current, which flows through the power lines and in the grounding system itself, and the short circuit time, depend of the type of the grounding of the neutral point of the network and the characteristics of the relay protection system.

The author of this article has 20 years experience in power installations, testing, control and maintenance. Let’s see which advices he does give us to keep it safe and effective…


A good grounding system should provide the maximum safety from contact, electrical system faults and lightening. For a grounding system to perform efficiently over long periods of time, it should be designed and installed using reliable materials and proven techniques.

grounding practices for safety and power quality 1

Grounding is the most important factor that governs the safety and the quality of a power system.

That’s on what Steven Mill wants to write today. Will you agree with his guidelines for safety and power quality?

“Grounding, also known as earthing, provides a safe way for the fault currents to pass on to the ground (neutral). This avoids sudden voltage spikes in the distributed network system, safeguarding the electrical equipment from permanent or premature failure. Grounding systems are generally designed keeping low-impedance paths in mind.

When a fault occurs, a low-impedance current flow path can result in discharging high volumes of current into the ground pretty quickly, keeping the equipment safe. Grounding also plays a vital role in transferring transients caused due to lightning strikes into the ground safely and quickly.”

Following are the recommended grounding practices according to me and maybe to you all:

Last time we shared an article about the top 10 ways to increase energy efficiency and performance of pumping systems.

Now here’s another interseting top 10 of the most prominent grounding systems for industrial sectors…

…But before that, let us first understand what grounding/earth is.
