14. A cathodic protection configuration, comprising:
-
a cathodic protection system including a cathodic protection rectifier having an anode and cathode;
a relay operable, in a closed position, to connect the anode to a groundbed; and
an interrupter coupled to the relay and operable to execute a program to cycle the relay between an open position and the closed position wherein the interrupter is operable in a stand alone configuration in which interrupter input is provided locally and wherein the interrupter is further operable in conjunction with a remote monitoring unit (RMU), wherein input to the interrupter is provided remotely via the RMU.
