This section of ZANDZ.com is designed to help designers, specialists of installation companies and maintenance services to respond to the most actual questions about design and installation of grounding and external lightning protection systems.
The section is a collection of regulatory documents, analytical reports and recommendations for the design of grounding and lightning protection.
1. Calculations
Calculation of grounding devices
This part gives formulas for calculating modular grounding in the form of one or more of grounding devices, as well as for electrolytic grounding, taking into account soil characteristics and size of grounding devices.
How to determine the right amount of grounding electrodes, and how to combine them into a single ground electrode system - read on an individual page.
Soil resistance
Specific soil resistance is a necessary parameter for the calculation of grounding. There is a table on the page with approximate values of this parameter for different types of soils in Russia and Kazakhstan.
More details on an individual page.
Design of grounding and lightning protection
The section contains useful information, recommendations, examples of projects in PDF and DWG (AutoCAD), the general principle of the calculation of estimates and methods of calculation is described there.

Lightning protection of oil and gas facilities
Useful article for lightning protection designers for oil and gas properties, the purpose of which - analysis of regulatory requirements for lightning protection of the facilities with large amounts of fossil fuels and assessment of their adequacy and appropriateness. This is important, because the right choice of lightning protection elements eliminates unwarranted expenditures of material resources and conflicts with the state technical inspection.

Lightning protection of residential and public buildings
Article by Professor E.M. Bazelyan, which provides answers to the most popular task of a designer. As a permanent participant of various conferences and seminars, the professor learned to look at the problem of lightning protection through the eyes of designers. Find out all the details in the design of lightning protection and become a guru in your sphere!

How to choose lightning rods?
Being the highest point among surrounding objects, a lightning rod takes a lightning strike upon itself and passes it to the ground electrode system through down conductors. It would seem that all that remains to be done is to install a lightning rod on the roof. It's not all as easy as it seems. Domestic and Europe regulatory documents contain conflicting requirements to the choice of lightning rods, which causes difficulties in the design and installation of external lightning protection systems. So what to do? See the answer in the article on that topic by Professor E.M. Bazelyan!
Recommendations of European standards on grounding
The experience of Polish colleagues who carefully analyzed the latest regulations on lightning protection is given here. This will help Russian developers of standards and designers to avoid wrong decisions.
