Primarily used for the detection of cathodic protection parameters, it is an essential device in pipeline management and maintenance, deployed along the line according to testing functions. Test stations can be used for testing pipeline potential, current, and insulation performance, as well as for coating leak detection and AC/DC interference testing. A test station is a specialized auxiliary device used in pipeline cathodic protection, equipped with potential test probes to evaluate the protected pipeline.

Functional Classification of Test Stations

1. Potential Test Station: Mainly used to detect protection potential.

2. Sacrificial Anode Test Station: Used to connect sacrificial anodes and measure their performance parameters.

3. Current Test Station: Measures current in the pipeline. Protection Effectiveness Test Station: Connects test coupons.
