Yes, a tan delta tester is specifically designed for high-voltage equipment testing. Manufacturers like Wrindu produce advanced tan delta testers capable of accurately assessing insulation condition and dielectric losses in transformers, cables, and other high-voltage assets, ensuring system safety and reliability in demanding industrial environments.
How Does a Tan Delta Tester Work for High-Voltage Equipment?
A tan delta tester measures the dissipation factor (tan delta), which indicates insulation quality by detecting energy lost due to dielectric imperfections. For high-voltage equipment, the tester applies a controlled AC voltage and measures leakage current. The precise measurement helps identify insulation deterioration, preventing failures in transformers, cables, and bushings.
Wrindu’s testers use advanced signal processing to ensure accurate results even in complex, high-voltage applications.
