The filler of the electrolytic ground terminal contains salts that lower the freezing point of the soil. As a result, a talik zone is formed, where the soil's freezing temperature is lower than it would be under natural conditions. If the electrode is installed too close to the foundation, the difference in the deformation of the thawed and normal soil can create an uneven impact on ...
ZANDZ.com professional knowledge hub about LIGHTNING PROTECTION and GROUNDING: articles and training webinars, solutions
All news (+ subscription)
A few years ago, we published a lightning protection design project for the railway terminal and station on our website. We have recently updated this project in accordance with the current regulatory and technical documentation and available ...
Professor Eduard Bazelian has published a new article on our website titled "In what cases can lightning ignite a gas mixture?". The subject of the article is the problem of lightning protection arrangements for facilities where gas is released into the atmosphere. ...
Useful Materials
Popular online seminars for designers and service professionals provide an opportunity to gain valuable knowledge about the design and maintenance of protective equipment, share experiences with Russian and foreign colleagues, and learn about modern and unique lightning and surge protection methods used around the world.
The materials are created by highly qualified experts and are designed to help designers, engineers, installers and maintenance services to answer the most pressing questions in the design and installation of grounding and lightning protection systems.
Projects of protective systems of facilities of various types are described in detail. For example:
- grounding for a transformer substation
- lightning protection of warehouse from sandwich panels
- lightning protection of shopping mall
- lightning protection and grounding of the car service center
The documentation is in DWG and PDF format.
The book is addressed to engineers - designers of external and internal lightning protection of surface structures. It is based on the practical experience of the author and the staff of the Laboratory of the G.M. Krzhizhanov Energy Institute, which he directs.
A brief description of the lightning mechanism and its parameters necessary for lightning protection design is given. Domestic regulatory documents on lightning protection are analyzed, with a focus on ...
The calculated specific electrical resistance of the ground (Ohm*m) is a parameter that determines the level of "electrical conductivity" of the ground as a conductor, i.e. how well the electric current will flow in such an environment from the earth electrode.
Data on many types of soil from various sources are collected.
An article for beginners, describing in simple language the knowledge of grounding.
The first part describes the terminology, the main types of grounding (purpose) and requirements for grounding.
In the second part - the story about traditional solutions used in the construction of earthing devices, listing the advantages and disadvantages of these solutions.
The third part contains a description of the new technologies used ...
The fundamental difference in the operation of devices "green lightning protection" and traditional (or active) lightning receivers, is the difference in the principles of operation - the isolation of the object from lightning, rather than deliberate reception, interception of lightning on itself. This allows you to avoid the most dangerous and hard-to-beat enemy of sensitive electronic equipment and flammable materials - the electromagnetic wave from the lightning channel, lightning receivers and current collectors (the secondary striking factor of lightning).
Electrolytic grounding ZANDZ is designed for use in permafrost, stony or sandy soils with high resistivity (from 300-500 Ohm*m), without the use of special equipment and bulk ground. Installation and calculation of such grounding is very simple. But behind this simplicity there are high-tech and modern solutions aimed only at uncompromising quality of the result.
