Abstract: A cathodic protection system comprising a short message system (SMS) transceiver. The SMS transceiver comprises a modem having a telephone number uniquely associated with it and a processor coupled to the modem. The processor is configured to retrieve sensor data from an input module of the cathodic protection system in response to an incoming SMS message from a remote telecommunication device when the incoming SMS message complies with a predetermined format. The processor is also configured to retrieve output voltage and current data from a rectifier monitor of the cathodic protection system in response to an incoming SMS message from the remote telecommunication device when the incoming SMS message complies with the predetermined format. The processor then sends the retrieved data to the remote telecommunication device via an outgoing SMS message.

Abstract: Controlling electric power inputs to cathodic protection rectifiers and monitoring the rectifiers. A rectifier controller connects between the power source and the rectifier and adds remote control and monitoring features to the rectifier. In an aspect, the rectifier controller described herein enables a user to control the rectifier over the entire output range rather than merely at tap-step settings. In another aspect, the rectifier controller described herein enables remote monitoring and control of the rectifier.
