Test Stations (Junction Boxes)
Test stations, also known as measurement boxes, are field devices used in cathodic protection systems to monitor, measure, and record current and potential values.
They are critical for observing system performance, controlling anode current distribution, and detecting possible failures at an early stage.
With more than 22 years of engineering experience, Edopec designs and manufactures durable, long-life, and modular test stations suitable for harsh outdoor environments.
For each project, the appropriate test station configuration is selected based on pipeline length, environmental conditions, and system type.
Function of Test Stations
In cathodic protection systems, test stations are used to measure potential differences between anodes, structures, and reference electrodes.
This allows operators to regularly monitor system performance and make necessary adjustments.
Their primary functions include:
-
Measuring potential differences and current values
-
Testing anode and structure circuits
-
Monitoring the continuity of cathodic protection
-
Facilitating fault detection and simplifying maintenance
-
Providing data logging and traceability
Edopec test stations are suitable for both manual measurements and remote monitoring (telemetry) integration.
Edopec Engineering Approach
Edopec evaluates environmental factors, system configuration, and monitoring frequency for each project site to determine the most suitable test station design.
All products are manufactured to ensure outdoor durability, safe access, and easy measurement capability.
