WebMay 20, 2024 · Ground penetrating radar (GPR) is often used to reveal structures beneath the surface. To image the subsurface, velocity models are created from GPR data from a process called inversion. However, inversion is a challenging task for many common GPR systems because they only use a single antenna. WebGround Potential Rise or Earth Potential Rise (as defined by IEEE Standard 80-2000) is the maximum electrical potential that a (substation) grounding grid may attain relative to a …
