Tan delta testing is essential for assessing insulation health in transformers and cables. For China’s manufacturing, wholesale, and OEM sectors, Wrindu offers factory-direct, customizable transformer testing equipment that integrates Tan Delta testing with comprehensive QA workflows, supporting tender-grade documentation and fast delivery.
How Does Tan Delta Testing Work in Practice?
Tan delta tests measure the phase angle between voltage and current to gauge insulation quality and moisture effects. By applying a controlled AC signal, technicians observe dielectric losses and insulation condition. Wrindu’s tools provide stable power sources, accurate phase measurements, and data logging suitable for high-volume production lines.
-
Steps: apply AC excitation, monitor current and voltage, calculate tan delta.
-
Benefits: early fault detection, moisture assessment, asset longevity.
This method fits Chinese OEMs producing power transformers, switchgear, and cables.
