Extensive and increased collocation of high voltage AC (HVAC) electrical transmission lines, coupled with advances in coating technology, has resulted in the emergence of the possibility of transfer of electrical energy from the HVAC line to paralleling utilities through electrical induction. That transfer of energy can result in safety risks for personnel, as well as corrosion risks for below grade assets. In order to mitigate those risks, operators ground the induced AC using grounding electrodes, typically consisting of bare copper cabling or zinc ribbon.

Electrical potential surveys are typically required to be completed on a periodic basis on cathodically protected structures such as underground pipelines. However, proving that a cathodic protection system is providing the degree of corrosion protection required can often be a time-consuming and error prone endeavor. It is a typical practice, and often required, to interrupt the CP source(s) to carry out these surveys, the accuracy of which is affected by several factors, including the presence and inherent function of DC decouplers.
