2. A simple explanation - a Counterpoise is an extension conductor that connects the main ground grid to a remote grid or a ground electrode. It typically runs along with a overhead line, e.g.skywire or ground wire, and it helps the main grid to dissipate a fualt current by parallelling more ground conductors to the grid, hence reduce the GPR.
