Tan Delta

The HVI Tan Delta system provides precise dissipation factor (tan δ) diagnostics for cable insulation assessment. Used together with HVI VLF generators, it measures dielectric losses to identify aging, moisture ingress, and insulation deterioration according to IEEE 400.2 guidelines. The system offers real-time trending, automated evaluation, and high-resolution data capture. Rugged and portable, it supports both acceptance testing and predictive maintenance programs for utilities and industrial users.
