Factory Price Automatic Multifunctional 0.05 class Accuracy Variable-Frequency CT PT Analyzer

• 5.7’ LCD screen, display clearly even under sunshine.
• Rotating photoelectric mouse, easy to operate.
• Build in printer to print test result automatically after testing completed. 
• Full functions, satisfy all kinds of CT(protection CT, measuring CT, TP) test requirements, such as excitation characteristic test, turn ratio, polarity, secondary winding resistance, secondary burden, ratio error, angular difference and etc. Also it can be used to test excitation characteristic, turn ratio, polarity, secondary winding resistance, ratio error, angular difference and etc all kinds of PT.
• Auto test CT/PT parameters on knee point voltage/current, 5% and 10% deviation curve measurement, Accuracy limit factor (ALF), safety factor (FS), second time constants (Ts), residual magnetism factor(Kr), saturated and unsaturated inductance.
• Accurately measure ratio error and angular error. Max. Ratio error ±0.05% is permitted. Max. Angular error ±2min if permitted. It can measure 0.2S class CT and turns ratio range is 1-40000.
• Complied with IEC 61869-1 to 3 standards of all kinds of CT/PT.  
• Using variable frequency method can make CT test when keen point is up to 60kV.    
• Easy to use. To test CT DC resistance, excitation and polarity only by one button. All CT tests adopt same one connect method except load test.
• To export test data by U disk.
• 1000 groups’ data storage, data can be saved even power failure.
• Friendly interface, English graphical interface.
• Small size and portable, weight less than 10KG.
