CPT-III Automatic CT PT Analyzer is used to measure all kinds of current transformers and voltage transformers.
CPT-III Automatic CT PT Analyzer can calculate the ratio errors and phase angle errors of the current transformer and voltage transformer at the rated burden and working burden in one test.
CPT-III Automatic CT PT Analyzer can automatically evaluate the test results according to the selected standard to determine whether the transformer is qualified.
