Grounding is an important aspect of every electrical distribution system. A properly designed and well-maintained grounding system significantly reduces the chance of personnel electrocution, electrical fires, equipment damage, and associated downtime.
Do you know that chemically treating the soil can be an effective method to achieve lower soil resistivity?
Chemical grounding rods, such as CHEM rods by LEC, can provide a permanent soil treatment solution for a low-impedance ground. The electrode is composed of a 2” or larger hollow copper rod and filled with an electrolytic salt mixture. The rod derives moisture from the soil and atmosphere. It utilizes the moisture to slowly dissolve the electrolytes in the rod, creating a conductive rooting effect, providing an ever-increasing lower resistant ground in any type of soil. The rod should be refilled periodically to provide long-term soil treatment.
For a piece of electrical equipment to operate, a complete path for current flow must exist between the source of the power and the piece of electrical equipment.
Electrical equipment such as transformers, motors, switchgear, cable, and bus contain energized and non-energized components. When an energized component comes in contact with a metal case or structure of a piece of equipment, it is commonly known as a ground fault. The case or structure will be at system voltage if a ground fault occurs. This is a very dangerous situation. When a metallic object or person touches the equipment, current will flow through the object or person to the ground. This can severely injure or kill the person and will cause extensive equipment damage. A properly designed, installed, and maintained grounding system can prevent this from occurring.
A system ground is grounding rod(s) bonded together and connected to the system's power supply. Chem rod by LEC is a maintenance-free rod that provides consistent, long-term mineral release into the surrounding soil, providing a low-resistance interface with true earth.
LEC has gained years of experience solving grounding problems for various industries. Petrochemical, LNG, nuclear facilities, data centers, process control, and many other industries benefit from the superior results achieved by these CHEM grounding rods.
