E&S Grounding Solutions provides IEEE 80-compliant grounding system design for transmission and distribution substations of all voltage classes, from 4 kV distribution substations to 500 kV transmission switching stations.
Our substation grounding services include: soil resistivity testing using the Wenner four-pin method per IEEE Std. 81, layered-earth soil modeling using SES CDEGS software, ground grid conductor sizing, ground potential rise (GPR) analysis, step and touch voltage calculations, and PE-stamped grounding drawings and reports.
We design grounding systems to meet the safety limits of IEEE Standard 80 (Guide for Safety in AC Substation Grounding) and verify compliance with tolerable step and touch voltage thresholds for both 50 kg and 70 kg body weight models.
Deliverables include: soil resistivity test report, CDEGS grounding model, step and touch voltage analysis, grounding system design drawings, and a PE-stamped final engineering report.
We serve utilities, independent power producers, EPC contractors, and government agencies worldwide. Contact us at +1-310-318-7151 or info@esgrounding.com.
