Abstract: A pair of spaced apart probes abut a metal component. A housing has a voltage measuring device coupled to the probes to measure the potential difference therebetween and a transmitter for transmitting potential difference measurements from the voltage measuring device over a network. A computing device connects to the network having an interface, a processor, and memory programmed with executable instructions. The potential difference measurements are received through the network. Output is generated for displaying the potential difference measurements with warnings on the interface when the potential difference measurements exceed or fall below predetermined threshold correlated to at least one of a corrosion phenomenon, a corrosion form, and a critical corrosion property.

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: The graphitization of a sample having a sample surface and bulk material adjacent to the sample surface is determined with a housing holding a potentiometer and a processor connected to the potentiometer. The processor receives electric potential measurements from the potentiometer at the sample surface and uses the electric potential measurements to quantify the graphitization of the bulk material adjacent to the sample surface to generate graphitization data for output.
