PORTABLE CATHODIC PROTECTION CURRENT INTERRUPTER

摘要

The portable cathodic protection current interrupter is a programmable, portable current interrupter for selectively controlling current interruption to a cathodic protection system. A processor and a voltage regulator are disposed within a portable housing and are in communication with one another. The voltage regulator is adapted for communication with an external power source. A display and a user interface are each mounted on the portable housing. An onboard clock is in communication with the processor for controlling the frequency and duration of current interruption signals. A global navigation satellite system receiver is provided for synchronizing a time signal of the onboard clock. At least one on-board relay is provided for communication with the cathodic protection current source for selectively interrupting current thereto. The portable cathodic protection current interrupter provides selective switching of the relay(s) between a main interruption channel, a testing interruption channel, and an external interruption channel.
