CPT-III Automatic Advanced CT Analysis CT PT Tester Current Transformer CT Analyzer

Product Description

CPT-III Automatic Advanced CT Analysis CT PT Tester Current Transformer CT Analyzer

Product Description

CPT-III Automatic Advanced CT Analysis CT PT Tester Current Transformer CT Analyzer is used to measure all kinds of current transformers and voltage transformers.

It can calculate the ratio errors and phase angle errors of the current transformer and the voltage transformer at rated burden and working burden in one test.

CPT-III Automatic Advanced CT Analysis CT PT Tester Current Transformer CT Analyzer can automatically evaluate the test results according to the selected standard to determine whether the transformer is qualified.
