GPS Current Interrupter

GPS Current Interrupter (GPS Synchronized Current Interrupter) is a key device in cathodic protection systems used for accurately measuring the polarized potential of pipelines. It employs GPS satellite synchronization technology to achieve precise periodic on-off control of the protective current, thereby accurately obtaining the pipeline's "instant-off potential" (OFF potential) and eliminating the influence of soil IR drop.

Core Functions and Working Principle：

1. GPS Synchronized On-Off: Receives the second-pulse time signal from GPS satellites, ensuring that multiple interrupters and detection equipment perform on-off operations at the same precise moment, achieving synchronization of measurements across the entire pipeline.

2.Accurate Potential Measurement: Measures the true polarized potential of the pipeline at the instant the current is interrupted, which is the most reliable parameter for evaluating cathodic protection effectiveness.

3.Multi-Device Coordination: On long-distance pipelines, multiple interrupters can be deployed to connect to different cathodic protection current sources simultaneously, working in coordination with CIPS detection hosts, data loggers, and other equipment.
