Abstract:
A system and method for regulating an adjustable DC supply and continuously and remotely monitoring measurements of reference cell potential and/or current for cathodic protection of a structure is disclosed. Cathodic protection devices use a logic circuit and/or microprocessor based monitor for removing identifiable components and noise from the system to arrive at the DC bias. A method is implemented herein to arrive at the true value of a reference cell potential measurement determined within a sample collection point or window calculated for the reference cell signal while the impressed current is still being applied. This measurement can be compared to a calculated shutdown and is communicated to a central computer accessible via a network such as the Internet. All output is automatically regulated and checked for target window accuracy using an automated voting scheme.
