Basic CP Circuits - Electron Theory and the Use of Meters in CP Circuits

Electron Theory and Proper Use of Meters in Cathodic Protection Systems

Electron theory explains that all matter is composed of molecules, protons, neutrons, and electrons. Ohm's Law is fundamental in cathodic protection (CP) systems, determining resistances in anodes, wires, and circuits. Voltmeters are essential tools for measuring AC and DC voltages in CP circuits. When working with rectifiers, it’s important to use the correct meter for the job, with a recommendation to always have a backup meter for redundancy. Use different meters appropriately for the rectifier and CP circuit checks.
