FAQ

What testing services does Reynard provide?

Reynard provides a full range of high-voltage testing services, including AC Resonance Testing, VLF Testing, Partial Discharge (PD) Measurement, DAC Testing, TDR Fault Location, insulation resistance testing, Tan Delta measurements and commissioning support.

Do you provide testing for both offshore and onshore projects?

Yes. Reynard operates dedicated mobile testing units for both environments. Our offshore testing unit supports cable systems up to 66 kV, while our truck-mounted onshore testing unit is designed for cable systems up to 400 kV.

Can Reynard perform testing as a standalone service?

Yes. Our mobile testing units can be deployed independently or as part of a wider Reynard project scope. We regularly support EPC contractors, utilities, cable installers and asset owners with commissioning, verification and diagnostic testing.

When should high-voltage testing be carried out?

High-voltage testing is typically performed after cable installation, following repairs, before energisation or as part of condition assessments for existing assets. It verifies the integrity of the cable system and helps identify potential issues before they lead to failures.

Why choose Reynard for mobile high-voltage testing?

Our testing specialists combine advanced mobile testing equipment with years of practical experience in high-voltage cable installation and commissioning. That means we don't just provide test results—we understand how high-voltage systems behave in the field and help customers move safely towards energisation.
