Introduction: GDGS Automatic Transformer Power Factor and Tan 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. Technical Index: 1.
