Frequently asked questions

▶ What is high-voltage testing?

High-voltage testing uses specialised methods like VLF and DAC to assess electrical systems, ensuring reliability, reducing failures, and extending asset life.

▶ Why is offshore high-voltage testing important?

Offshore testing uses dual resonant systems to cut testing time and costs. This efficient process maintains accuracy and reduces downtime in challenging marine environments.

▶ What are VLF and DAC tests?

VLF (Very Low Frequency) and DAC (Damped Alternating Current) tests detect cable defects up to 400kV. Early detection prevents costly outages and improves long-term system health.

▶ How does Partial Discharge (PD) detection help?

PD detection identifies weaknesses in insulation before they cause failures. This proactive approach enables targeted maintenance, boosting safety and equipment longevity.

▶ Who benefits from these testing services?

Asset managers and project teams gain actionable insights for preventive maintenance. Early issue detection leads to fewer unexpected failures, lower costs, and improved system performance.
