In this episode, E&S Grounding Solutions President David Stockin discusses Part 5 of a 5-part series about lightning strike scenarios and the ways to protect against them.In the previous four episodes, we discussed the 4 lightning scenarios that cause damage: cloud-to-cloud strikes, nearby ground strikes, strike to incoming power lines, and finally direct strikes to your building. These problems can be resolved with the following lightning protection strategies: First, a Frank...

In this episode, E&S Grounding Solutions President David Stockin discusses Part 4 of a 5-part series about lightning strike scenarios and the ways to protect against them.Direct lightning strikes are the fourth and least common scenario that can damage your building. However, a direct lightning strike can be very powerful and cause major damage. The odds of a direct strike to your building will depend on the lightning strike frequency in your area. Due to the high curren...

In this episode, E&S Grounding Solutions President David Stockin discusses Part-3 of a 5-part series about lightning strike scenarios and the ways to protect against them.Ground strikes are the second most common source of lightning damage, due to the direct coupling of ground currents traveling through the earth and into the concrete encased steel components of a structure. These steel components will need to form there own magnetic fields which in turn will can cause damage to ele...

In this episode, E&S Grounding Solutions President David Stockin discusses Part-1 of a 5-part series about lightning strike scenarios and the ways to protect against them. Air-to-Air strikes are the most common source of lightning damage, due to electromagnetic fields (EMF) and the damage this interference causes to electronic systems. Understanding how the EMF from lightning cause damage to your structures is key to understanding why the solutions work and how lightning protec...

E&S Grounding Solutions President David Stockin responds to viewers' questions about the differences between ground “loops” and ground “rings”. Ground loops are a common term that is often ill defined and even more often used inappropriately. Typically, ground loops are used to define a process where the return currents (neutral currents) are allowed to travel back to the source on the normally-non-current-carrying-exposed-conductive-parts of a circuit, in violation of NEC 250.6 –Objectio...
