Series Resistances and AC to DC Conversion in Cathodic Protection Systems
This video explores the role of series resistances in cathodic protection (CP) systems, including metallic resistance in pipelines, ground bed resistance, shunts, diodes, and mechanical connections like CAD welds. The importance of checking for loose connections in rectifiers is highlighted, along with how shunts are used to measure current. It also explains the conversion from AC to DC through diodes and discusses the difference between pure DC and rectified DC, noting the impact of this conversion on system efficiency. Additionally, the video covers voltage cycles and the differences in electrical frequency (Hertz) between different regions around the world.
