Abstract
A system for monitoring and alternatively adjusting the electrical energy input and output of remotely located corrosion protection rectifiers on a section of a longer pipeline includes three elements. The first element is a monitoring unit which monitors electrical input, output voltage, output amperage and level of applied cathodic protection of the electrical energy provided to the pipeline by a rectifier. This data on electrical energy is then transmitted to the second element, a low-level communication satellite. The low-level communication satellite then retransmits the data to the third element, a management data center. The information received at the management data center may be monitored, recorded or transformed into adjustment signals which are then retransmitted via the low-level communication satellite back to the rectifier on the pipeline.
