Circulating ground current

WebAug 18, 2015 · It is my understanding that with this method there must be a ground rod or ground grid at the instrument location and the instrument ground must be bonded/attached. To me this presents the possibility of creating circulating ground current and/or induced voltage in the instrument signal wires. _____ WebNov 11, 2014 · I believe only one end is grounded because if a potential exists between the two grounds (i.e. locations where ground connection is made) then a circulating current will flow through the shield and ground. A current flow through the shield will result in a voltage drop in the shield.
