Ground Potential Rise (GPR) is the maximum voltage that a substation grounding grid may attain relative to a distant grounding point during a fault condition. GPR studies are required to protect telecommunications equipment, personnel, and connected facilities.
E&S Grounding Solutions performs GPR studies per IEEE Standard 80, IEEE 367, and AT&T/TELCORDIA requirements for substations, telecom central offices, and utility facilities.
Our GPR analysis determines the maximum GPR voltage, evaluates hazardous voltage transfer, and recommends mitigation measures such as isolation transformers, drainage cables, and protective relaying.
We provide PE-stamped GPR study reports. Contact us at +1-310-318-7151 or info@esgrounding.com.
