These new CT/PT testers are based on low frequency and variable frequency methods which lead to the great reduction in weight and high knee point test range. With one button click, all test items of the current transformer test set, such as excitation, winding resistance, polarity, phase error, ratio, etc, can be performed automatically.

PCT200Ai is the current transformer test set can finish various tests of different transformers. Compared with PCT200i,its accuracy is higher.This CT analyzer can test the 0.2s class CT.Only this CT analyzer - the high-accuracy current transformer test set has passed the tests held by Wuhan High Voltage Research Institute.The max permissible error of ratio measurement is ±0.05% and max phase measurement is ±2min.


  • Can test M/P/TP type CTand PT
  • Ratio check up to 35000:1 and 45000:5
  • Knee point check up to 45000 V
  • Standards: IEC 60044-1,  IEC 60044-6,ANSI/IEEE C 57.13
  • Result saved directly in Excel format
  • Report can be transferred to flash disk via USB port.
