JSY-03 Transformer Tan Delta Tester

This tester adopts modern technology to achieve automatic frequency conversion, analog-digital conversion and calculation, features strong anti-interference ability, fast test speed, high precision, automation, easy operation. Its high-power switch supply can output 45Hz and 55Hz pure sine wave, boost automatically with voltage up to 10kV. As the power frequency disturbing can be eliminated, it is suitable for field test in power plants or other places with strong electromagnetic interference, now widely used for dielectric Loss factor (tgδ) measurement of transformer, bushing, capacitor, arrester and other equipment.
