CPT-III Current Transformer and Voltage Potential Transformer Testing Equipment

Introduction:

CPT-III Current Transformer and Voltage Potential Transformer Testing Equipment is used to measure all kinds of current transformer and voltage transformer.

CPT-III Current Transformer and Voltage Potential Transformer Testing Equipment 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 Current Transformer and Voltage Potential Transformer Testing Equipmentcan automatically evaluate the test results according to the selected standard to determine whether the transformer is qualified.
