Providing lightning protection with Earthing Solutions for Buildings. Lighting energy is dissipated into the ground through these Earthing Solutions for Buildings. In order to minimize the risks of injury to people and equipment damage, the system should minimize the ground voltage potential rise.
Earthing systems are, in essence, subgrade conductor networks that allow electrical energy (originating from above-grade networks) to be transferred from the network to the ground. Lightning and surge protection devices work by redirecting voltage spikes and surges away from the electrical components they are protecting and dispersing them to a ground plane (using an earthing system), such as the ground or a copper pipe on the inside of a building.
The fundamental difference between earthing and grounding is that the term “Earthing” refers to the connection between the circuit and the ground, which is a zero volt potential. When a circuit is grounded, it is not physically connected to the ground, but its potential is zero compared to other points.
If there is a poor grounding connection, lightning may find another path, such as plumbing, to reach the ground, resulting in the same effect as a lightning strike. An improper grounding connection can result in a fire. It is not recommended to use simple grounding for such a system.
A lightning protection system intercepts this voltage, allowing the lightning current to enter the ground safely. The lightning rods do not decrease your chances of being struck by lightning, but they do provide a direct path to ground, eliminating fires, explosions, and electrical surges that can damage your home.
The majority of houses contain electrically conductive paths to the ground, but some do not – such as camping/fishing cabins. Depending on how the lightning makes its way to the ground, all bets are off.
