For many people who are new to the cathodic protection industry, stray current may be relatively unfamiliar. Stray current refers to the current flowing outside the design or specified circuit. If the cathodic protection current enters a structure that is not related to it, when the current flows into the structure part, the part is protected, but where the current leaves the structure, the structure is corroded.
Stray current can be divided into DC dynamic stray current, DC static stray current, AC stray current and geomagnetic stray current.
DC stray current detection:
In the pipeline design stage, the degree of stray current interference is evaluated according to the ground potential gradient.
