One high lightning rod or several low ones?

One high lightning rod or several low ones?

When choosing a design for external lightning protection, designers increasingly often choose high rod lightning rods, doubting the reliability of an air termination mesh or a series of smaller rod lightning rods. Is their choice correct? Is one, but a high electrode capable of reliably protecting an object? Let's analyze this question!

Is it necessary to make grounding in permafrost soil? There is a solution!

Is it necessary to make grounding in permafrost soil? There is a solution!

Many electricians and builders think about the choice of a grounding device used in permafrost soils. This is not surprising, because in the regions where the average annual temperature does not rise above -5C,  the ground simply doesn't have time to completely. Because of that its resistivity increases up to 1000 Ohm / m. What to do in this situation?  We answer!
