Abstract:
A method for regulating output and continuously and remotely monitoring measurements of reference cell potential or current for cathodic protection of a structure, comprising:providing one or more cathodic protection devices located proximate to said structure to vary said output; piggybacking an internal interface unit accessible by a central computer on each of said cathodic protection devices; communicating with each of said cathodic protection devices by means of said internal interface unit; providing and displaying said measurements to said central computer; comparing and cross-checking said measurements using a voting scheme, thereby improving confidence in said measurements; varying said output being applied to said structure as determined by said voting scheme such that said measurements fall within a target window; and removing distorting effects, residual components, and noise from said measurements to arrive at an amplitude for a DC bias, wherein said amplitude for said DC bias is correlated to said reference cell potential.
