On the DC side, baseline potential readings document structure condition before system energization or after modifications. On the AC side, baseline voltage measurements identify where induced AC from parallel power lines poses a corrosion or safety risk, providing the field data that drives mitigation modeling and design.
Pipe-to-soil baseline testing services include:
- DC pipe-to-soil potential measurements at test stations
- Induced AC voltage measurements along the right-of-way
- AC current density evaluation at coating holidays
- Data analysis by certified corrosion professionals
- Baseline documentation for compliance and future comparison
