Abstract: A metal structure is supported by a concrete foundation with a ground ring nearby. A telecommunication module configured to operate with a 5G wireless standard is mounted on top of the metal structure and separated from the metal structure by an insulating barrier. The ground ring has at least three monopole grounding wires. A grounding cable connects the telecommunication module to the ground ring. A base transfer station cabinet is offsite from the metal structure and includes a plurality of cabinet ground conductor wires connecting to the ground ring. A hybrid cable, comprising a supply cable and a return cable, connects the base transfer station cabinet to the telecommunication module. Any stray current from the telecommunication module is directed away from the metal structure by the insulating barrier, and the stray current is directed to the ground ring through the grounding cable.

Abstract: A system for detecting the formation of a crack in a metal joint includes an electrochemical electrical current detection device. Carrier material surrounds the metal joint, at least partially, with conductive media having electrolyte therein. An auxiliary electrode is in electrical contact with the carrier material. The placement of the auxiliary electrode in electrical contact with carrier material forms a passive layer on the metal joint. The formation of a crack in the metal joint ruptures the passive layer to generate a current for detection by the electrochemical electrical current detection device.
