Interference testing is performed when a structure is influenced by static or dynamic stray current. Various interference surveys and test methods are used to identify the stray current, design a mitigation plan for the stray current and perform follow up testing after the mitigation is installed.

Stray current sources

• Cathodic protection systems
• Welding operations
• AC or DC powered rail systems
• Mining operations
• HVDC or AC power lines
• Telluric or geomagnetic currents

Each of these sources of stray current requires a unique interference survey or testing procedure to identify the problem and design an appropriate mitigation system.
