What is the source of OFF-Step in instant off potential reading in cathodic protection systems, (such as results extracted by utilizing NACE TM0497)?

30 January 2016 0 3K Report

In the potential reading in a cathodic protection system, such as methods which is presented in NACE TM0497, OFF-Step potential is expected. The duration of OFF-Step could reach to more than one second while expected electrochemical surface phenomena doesn't take 1 second normally.
