Abstract
Based on on-site calibration test date; it is calculated and analyzed a current loop impedance in on site calibration of current transformers. And the conclusion is that because of the long test loop and the large loop impedance;there is large Var cost and low power factor in the loop. To reduce Var cost;the static Var compensator is used in the on-site test. The efficiency of on site test equipment is enhanced; and the technique level of on-site test is advanced. The Var compensator used in the test is produced. The effect used in current transformers calibration test is proved by the experiment.关键词
