Protect employees, limit over-voltages, prevent AC corrosion

The decoupler DASD provides protection against transient, temporary and long-duration over-voltages.

This means:

• Protection against impermissibly high touch voltages for people working on the pipeline
• Protection for systems and components
• Protection against AC corrosion

This has the advantage that the desired cathodic protection potential (DC potential) of the pipeline is not negatively affected.
