OFF POTENTIAL
OFF potential monitoring is an increasingly important aspect of a well designed cathodic protection system. It can offer important additional information about DC and AC corrosion.
OFF potential measurements carried out manually are labour-intensive, costly and (importantly) reactive - they do not identify corrosion problems but are merely spot current measurements taken after a corrosion problem may have occurred.
Abriox’s MERLIN Remote CP Monitoring System takes OFF potential measurements at transformer rectifiers and test posts automatically, analyses and stores the data and transmits it wirelessly to a central location. Off potential monitoring for CP is proactive - ie it identifies potential corrosion problems at the test station or test post and alerts the operator immediately. It has important economic, operational, safety and environmental benefits.
OFF potential monitoring using the MERLIN system is the ideal solution for an advanced CP system that montors transformer rectifiers and test posts.
