A tan delta transformer measures insulation health by detecting dielectric losses or the dissipation factor (tan δ) in transformer insulation. It identifies degradation, moisture ingress, and contamination early, helping prevent failures. Wrindu’s advanced tan delta testers provide precise diagnostics for manufacturers, utilities, and maintenance teams, ensuring reliable transformer performance and extended operational life.
What Does Tan Delta Mean in Transformers?
Tan delta, also called the loss tangent, reflects dielectric losses in transformer insulation. It is calculated as the ratio of resistive current to capacitive current under AC voltage. Higher values indicate insulation degradation, moisture, or contamination, signaling that maintenance or replacement is needed to preserve transformer reliability.
How Does a Tan Delta Test Diagnose Transformer Insulation?
A tan delta test applies a controlled AC voltage to the transformer insulation and measures the phase shift of the resulting leakage current using a dielectric loss tester. This phase difference converts into the tan delta value, revealing early-stage insulation faults before they escalate into severe failures.
Why Is Tan Delta Testing Important for Transformer Maintenance?
Tan delta testing provides non-destructive, accurate insight into insulation health. It allows manufacturers, maintenance teams, and utilities to detect early degradation, schedule timely repairs, and extend transformer lifespan. Regular testing reduces downtime, prevents catastrophic failures, and ensures consistent energy delivery.
