Comprehensive CT and PT Analyzer

CT / PT Analyzer:is used to measure all kinds of current transformer and voltage transformer. It can calculate the ratio errors and phase angle errors of current transformer and voltage transformer at rated burden and working burden in one time test. The tester can automatically evaluate the test results according to the selected standard to determine whether the transformer is qualified.
