Lightning is very damaging and so is the static build up from an electrical charge in the air during a lightning storm. While a direct lightning strike can cause fire or explosion, the static build up can cause a charge to run down the cables and damage connected equipment.
In other words, a lightning strike or static build up wants to get to ground and will follow the path(s) of least resistance to do so.
The grounding rod and the entire grounding system provide a direct least resistant path to ground, rather than into our equipment.
- Chem-Rod® is a Grounding rod electrode – it’s a conducting element buried directly in the ground, facilitating the flow of fault current towards the ground. It’s metallic, resistant to corrosion and an integral part of the grounding system.
- Grounding ensures that the electricity travels through a low-resistance path, when it flows from a source and returns through a neutral connection.
- A Grounding system is a set of equipment needed to dissipate lightning currents, surge and transient voltages
How does a grounding rod reduce resistance?
Chem-Rod – LECs manufactured grounding rod called Chem-Rod® which is an ultra-efficient grounding electrode designed to provide optimal low resistance, low impedance interface with earth. Chem-Rod® achieves its full potential with Grounding Augmentation Fill (GAF) & LECWELD.
GAF - 95% of the resistance of a grounding rod is established by the soil within an area whose radius is 1.1 times the electrodes length. Augmented soil with GAF (a special formulated mixture to help create low resistance earth interface) backfill facilitates a low resistance ground connection. GAF has a low freezing point and expanding factor, and retains moisture better than local soil
LECWELD – it’s engineered to be an easy and efficient field welding system. No outside power, bulky gas tanks or other equipments associated with welding are required. It creates a permanent, homogenous and molecular bond that cannot loosen or corrode. It can also withstand more current that the conductor itself.
Installing a proper grounding rod in accordance to the international grounding techniques not only protects your facility from damaging surges and spikes, but also keeps your facility safe from any ill effects of latent system failure.
