Why Is It Difficult to Accurately Measure Pulse Grounding Resistance?

Why Is It Difficult to Accurately Measure Pulse Grounding Resistance?

Lightning discharge is a very short event. The current pulse takes several hundred microseconds. The lightning protection grounding arrangement should dissipate the lightning energy very rapidly. In such conditions, the grounding electrode capabilities strongly differ compared to "slow" 50 Hz industrial currents.

Collection of Materials for Lightning Protection of Educational Institutions

Collection of Materials for Lightning Protection of Educational Institutions

Kindergartens and preschools, secondary and special schools, colleges, institutes are public buildings that evidently require lightning protection. Protection of preschoolers, students, and their mentors is an important and responsible task. According to RD 34.21.122-87, such buildings should be protected from lightning in accordance with Category III (zone B). The second regulatory document, SO 153-34.21.122-2003, classifies this facility type as conventional, for which a system with any of four categories is provided with the reliability at least 0.8.

Laser-Controlled Lightning: A New Article on Our Website!

This is a publication of the report of the International Research Group related to the experiment conducted in the Swiss Alps in summer 2021. Experimentors have deployed their terawatt laser unit on the top of the Santis mountain, wherein the meteorological base with the telecom tower about 120 m high is located. The goal of the experiment is to demonstrate the ability to "direct" the lightning discharge along the path set by the laser beam.

Lightning Protection and Grounding in the 2023 Russian National Standardization Programme

Lightning Protection and Grounding in the 2023 Russian National Standardization Programme

The issue of completeness and harmony of regulatory documents takes a special place in the designer's life. The hope to promote GOSTs, industrial standards, etc. in terms of harmonization, completeness, and up-to-dateness is probably not relevant only for a novice designer. The National Standardization Programme (NSP-2023) has been developed to reflect the potential of the regulatory documents. It determines standardization direction for 2023-2024 and is governed by its own GOST R 1.14-2017.
