Sheath Fault Testing

Protecting the Cable's Outer Sheath

We provide sheath fault testing for underground power cables to detect leakage, damage, and insulation failure in the outer sheath — without affecting the conductor itself.

Catching sheath damage early helps prevent it from developing into a full conductor-level fault, and is often carried out as a preventative check.

• Detects sheath leakage & damage
• Non-invasive to the conductor
• Useful as a preventative check
