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.

  Functions of test software:
   	- Make evaluation for test results according to selected standards.
  	- Make word report for test result.
  	- Make word reports one time for multi-group test records on the PC.
  	- Calculate the ratio errors and phase angle errors at rated burden and working burden in one time test.
  	- Compare excitation curves with saved excitation curves in the same window.
