CPT-III Large Screen Automatic CT PT Analysis Instrument CT PT Analyzer

CPT-III Large Screen Automatic CT PT Analysis Instrument CT PT Analyzer

Introduction:

• CPT-III CT 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 test.
• CPT-III ct pt tester can automatically evaluate the test results according to the selected standard to determine whether the transformer is qualified.
