E&S Grounding Solutions provides comprehensive lightning risk assessments and lightning protection plans that will help to ensure that a lightning strike will not cause catastrophic failures. Our lightning risk assessment and proposed lightning protection plans illustrate the necessary steps that should be taken in order to meet the guidelines as set out in NFPA 780 and IEEE 998.
NFPA 780 provides lightning protection system installation requirements to safeguard people and property from fire risk. While NFPA 780 has no force in law, it is generally recognized as the primary lightning protection document in the USA. The purpose of NFPA 780 is to safeguard persons and property from lightning.
NFPA 780 tells you if your site needs a partial lightning protection system, or if you need a full system. We typically run both versions in order to determine where cost savings can be made.
Soil resistivity is a function of the concentrations of ionic soluble salts and the moisture level in soil. Soil resistivity testing measures a soil’s corrosivity and determines how well or how poorly the soil will conduct electrical current. Soil resistivity testing is essential when it comes to reliable electrical grounding design or determining the ground potential rise and calculating the 5-ohm resistance to ground. Knowing how conductive or resistive the soil is can be critical to properly protecting equipment and personnel.
A proper soil resistivity test can also save valuable time and money. It takes the guesswork out of the construction and design process and always gives a predictable outcome. The most reliable and widely accepted soil resistivity test in the world today is the Wenner 4-point Test Method.
According to the IEEE Standard 142-1991 (The Green Book), the grounding electrode resistance of large electrical substations should be 1 Ohm or less. For commercial and industrial substations including telecommunications sites, the recommended resistance to ground is 5 Ohms or less. This low resistance is required due to the high potential to the earth of the electrical system. Depending upon the site location and soil characteristics, achieving that 5-ohm resistance can be very difficult. With proper soil resistivity testing, however, we can provide grounding solutions that will achieve 5 ohm resistance to ground and meet the stringent requirements such as the Motorola R56 standard to keep your valuable equipment within warranty.
