A method for testing a cathodic protection system is disclosed where the system includes a cathodic protection rectifier configured to apply a voltage across a pipeline and a reference point. The method includes measuring a magnitude of an output voltage of the cathodic protection rectifier, transmitting to a site remote from the rectifier, the measured output voltage magnitude using a cellular control channel, receiving the transmitted measurement at the remote site, and using the transmitted measurement to determine whether the cathodic protection system is operational.
