Permanent Reference Electrodes

 

 

 

  In order to measure structure to soil potential during design life time, buried reference electrodes are used. These electrode have a specific life time and are known as permanent reference electrodes. These anodes are effective when constant potential transformer rectifiers are used or when there is limited access to the structure. Some of the common applications of these anodes are monitoring the potential of below structures:
  • AST bottom plates
  • Water storage tanks (Internal surface)
  • Under concrete slabs
  • Beside underground pipelines
Ag/AgCl, CuCuSO4 and zinc electrodes are the most common permanent reference electrodes in Cathodic protection industry. Permanent reference electrodes are typically designed for 20 to 60 years old life span. In order to increase the life time, these anodes are usually packed in a backfill with similar composition of sacrificial magnesium anodes' backfill. PSN manufacture and supply permanent reference electrodes.
