New extended zandz interception rods

New extended zandz interception rods

Sometimes conventional interception rods are insufficient. In this case, they may be extended by only several dozen centimeters to increase the reliability of the lightning protection. This extension may be required, e.g. to compensate for the interception rod's height fluctuations due to flat roof sloping.

We invite you to the webinar

We invite you to the webinar "The danger of extended underground communications in lightning protection."

Any metallic communication is a high-risk element in lightning protection because it can transmit lightning overvoltage over long distances. However, the defining word "underground" is included in the title. Such communication is not alarming, intuitively. There is a false illusion created by the enduring habit of believing that grounded is safe! The webinar will cover all particularly dangerous manifestations of overvoltage transport over such communications, with a focus on the consequences for the human body.

Specifics of Lightning Protection of Treatment Facilities

Specifics of Lightning Protection of Treatment Facilities

Treatment facilities are a critical set of devices and structures for treating water to the parameters established in regulatory documents and sanitary requirements. The set of facilities usually includes devices for mechanical, biological, and physical/chemical treatment of sewage water. Passing through the treatment facilities, industrial and urban sewage water is separated from mineral, organic, radioactive, and other harmful substances. After this treatment, water is direct to the urban drainage system for additional treatment, drained into the environment, or used for technical purpose.

What is the issue with active lightning arresters? Professor E.M. Bazelian explains

For decades, experts have debated the viability of active lightning protection. It is quite clear that to improve the protective effect of the lightning arrester, it is necessary either to increase the electrical strength of the air along the path of the lightning to the object, or to reduce it on the way to the arrester.
