New article by Prof. E. M. Bazelyan: “Measuring Grounding Resistance in Dense Urban Areas”

A new article by Prof. Eduard Meerovich has been published, based on a recent webinar about the challenges of measuring grounding resistance in a city, where—because of tight space and soil-borne interference—standard test setups are not suitable. It also covers the use of clamp-on meters as a practical substitute.

News Update from the ZANDZ Technical Center — No. 38

  • 18.09.2025

The ZANDZ Technical Center celebrated its 19th anniversary, continuing to gather and preserve knowledge on lightning protection and grounding. Team members held meetings with engineers at 12 organizations, discussing calculation specifics for complex facilities, optimizing design solutions, and reducing costs. A livestream on calculating lightning protection for a furniture factory took place, and five more such events are planned. Numerous solutions were developed for facilities across different regions of Russia.

Features of Using "Green Lightning Protection" for Tall Structures

"Green lightning protection" is perhaps the most unusual lightning protection system. The main point is that "green lightning protection" is not a lightning rod. It works differently: it doesn't intercept a lightning strike but uniquely conceals the object beneath it, making a strike on it impossible!

Methods for calculating grounding electrode dissipation resistance: what are the differences and how to choose?

The material, prepared by a Zandz.com technical specialist, compares formulas from various authoritative sources — reference books by Barybin, Karyakin, RD standards, and others, including RD 34.35.514-85 "Instructions on the Operation of Overvoltage Protection Means". These documents contain different methodologies for calculating the resistance of vertical and horizontal grounding electrodes. All these approaches are used in design practice—but is there really a fundamental difference between them?

The ins and the outs of urban grounding design: problems and solutions

The ins and the outs of urban grounding design: problems and solutions

Creating a grounding arrangement in a city is complicated by limited space available. The territory around the building is usually covered with asphalt or occupied by neighboring buildings. In most cases, open areas (such as flower beds or lawns) are pretty small. Even if large-scale construction works are provided during the design, numerous underground utilities installed under the ground do not allow installation of the grounding arrangement in close proximity. However, designers still have several possible options.
