Video of electrolytic grounding installation!

At the installation of a grounding device, you may encounter a situation where installation space is limited. It is impossible to establish a deep-laid ground electrode due to strong soil, for example, in conditions of permafrost, rocky and sandy soil, or there is only a small area to place the grounding contour. For such cases, electrolytic grounding system has been developed. It allows providing the necessary resistance in extreme conditions. In this article we describe installation of such a system in detail on the example of our partner.

How to protect a single family house from lightning?

The storm, accompanied by rough winds, heavy rain, thunder and lightning flashes became a common sight this summer in Siberia. Every time it carries different damages from temporary power outages in some areas of the city, to the fire, destroying homes and property of citizens. Owners of single-family houses, cottages and garden plots, taking care of safety of the relatives and electrical equipment, more frequently think about protection against lightning and its secondary effects. What danger does lightning bring and how to protect against it? http://www.zandz.ru/news/Kak_zaschitit_chastnyiy_dom_ot_molnii

How does lightning originate? Learn from the unique video

Thanks to the modern technology, we can study the causes of such complex natural phenomena as lightning. Lightning is described in sufficient detail in scientific literature, but it is incredibly difficult to capture its rapid flight in the atmosphere.
The employees of the Institute of Technology in Florida managed to make slow motion of lightning during a heavy storm in May 2016. The scientists tested a new high-speed camera with the playback speed of 7000 shots per second! These shots can be compared to a work of art. Every new electrical discharge turns into a bright flash. It looks like a special effect in an adventure film, which you can see not on the big screen but in real life. The video shows that prior to envelop the sky with an explosive flash, the lightning starts a storm cloud and goes to the ground. It tells us that this is a downward lightning.
Such experiments allow to track the process of the discharge origin, to explore its characteristics and later develop technologies that affect the trajectory of lightning itself.

To have or not to have a lightning rod?

Lightning discharge is a complex atmospheric phenomenon, the time and place of which is unpredictable. Today it is possible to calculate the probability of a lightning strike into an object, since it depends on many parameters of the building: height, size, location relative to the objects of larger and smaller height, intensity of storm activity and other factors. Every owner of a private house or villa, planning external lightning protection system, questions himself: if the lightning rod placed on the house collect all the lightnings in the area? Also, whether it would bring more harm than good? We will get answers to these questions on the calculation example.

How to stay in business for 120 years?

Every organization, like any living organism, has its lifespan. In times of an unstable economy, this period is much shorter. Decrease in sales is the reason for that and as a result, the company's closure. But it does not happen with all organizations. The company WJ Furse & Co Ltd is an example of a long life - the world leader in the design and manufacture of grounding and lightning protection systems. The company, which lived through two world wars and has been existing for 120 years! How did it manage to do that?

How to design grounding for MRT unit?

The technological grounding or as it is called "functional", "operative" is not intended for electrical safety but for a proper operation of the electric installation. The value of such grounding resistance is determined by the equipment manufacturer and is indicated in the certificate or maintenance rules to the equipment. Such equipment typically has precise electronic systems, for the operation of which it is necessary to eliminate any interference. This can be either a machine at any production, and medical equipment such as MRT, ultrasound investigation or cryocapsules. Resistance of the functional grounding device can be from 0.1 to 2 ohms.
Our Technnical Center recieved a request to help calculate the technological grounding resistance of less than 1 Ohm for MRT unit in one of the hospitals of Moscow region. The problem was that the area for the installation of grounding was very limited. We offer you a solution of this task.

What is the advantage of GALMAR rods compared to the rods from other manufacturers?

The grounding equipment market today is full with a variety of products and solutions from different manufacturers from different countries.
Technological processes are not static, and the appearing of other manufacturers of grounding is quite expected. Of course, the consumer often has the question: what manufacturer to choose and not to lose? To dispel any doubts, lets consider the important characteristics of grounding equipment and compare ground electrodes produced by GALMAR with the products from other manufacturers.

Can I use roof as a lightning rod?

Metal roofing is the easiest and most affordable way of roof covering for a single-family house. Such a covering has a long service life, is easy to assemble and corrosion- resistant. Such materials as zinc, zinc- titanium, steel, aluminum or copper can be used. It is widely believed that a metal roof does not need lightning protection, because it acts as an air terminal. But is it really so?

Installation of grounding in the Star City by the ZANDZ Club of Experts!

Our specialists regularly face the question from the clients why we recommend grounding made of copper-bonded steel? After all, for the decades, a grounding device was made of black metal, and it seemed there were no problems. Why the decision toleave the traditional grounding was made? Is it new fashion or really essential?
