Abstract
Communications systems are provided for use with an impressed current cathodic protection (ICCP) system having single or multiple ICCP components. A pipeline may be provided by connecting multiple pipeline sections together as an integrated pipeline where each section has an associated ICCP system. A communications signal comprising an AC signal is impressed on the pipeline and received by receivers associated with power supplies associated with each ICCP system. Upon reception of the AC signal, a controllable switch is operated within the power supplies to synchronously disconnect them from their power source and thereby enable accurate testing of the ICCP system.
