GDGS Automatic Tangent Delta Tester /Transformer Substation Tangent Delta Tester is applied to meaure the dielectric loss and capacitor value of insulating materials.

GDGS Automatic Tangent Delta Tester /Transformer Substation Tangent Delta Tester is applied to measure the dielectric loss and capacitor value of insulation materials in high voltage power equipment. The non-power frequency voltage source is integrated in the tester to avoid power frequency interference. That make the tester has a good performance in measurement precision.
