About the Talk

This talk will present the basic function of solid-state DC decouplers used in conjunction with cathodic protection (CP) systems and their common pipeline applications, including AC Mitigation and isolation joint protection.

In addition, this talk will review some of the challenges often encountered with obtaining accurate CP potentials on protected structures during interrupted surveys. Capacitors, which are essential components of decouplers used with AC mitigation systems, can in some situations influence instant-off measurements and lead the operator toward incorrect conclusions. This talk will explain the influence of capacitance on instant-off measurement response, illustrate the behaviour using several field installation examples and offer techniques to overcome the capacitive effects during interrupted surveys.
