“CTP-200” - Transformer Comprehensive Tester (frequency conversion, class 0.05)

  • peculiarity/
  • function/
  • parameter
  •     Testing CT/PT VA characteristics curve and 10% error curve based on advanced frequency variation method, it outputs only 180V AC voltage and 5A AC current when it gets the most. But this can handle the CT test when its inflection point gets up to 30KV.
     
        All-sized functions, it can be used in steady or transient state characteristic testing, such as excitation with every kinds of CT&PT types, transformation ratio, phase, polarity, secondary winding resistance, load, differential and angle difference.
     
        It will automatically give the parameters of inflection point voltage/current, 10% error curve, 5% error curve, ALF, FS, Ts, Kr, accuracy class, saturable and unsaturated inductance etc.
     
        Ability to test and calculate CT&PT according to different standards of GB1208-2006 (IEC60044-1), GB16847-1997 (IEC60044-6) etc.
     
        Beautiful interface, graphical interface all in Chinese, 6.4 cun LCD, visible in the sunlight.
     
        The device can store 3000 groups of testing data, no loss. And it can load data to analyze after testing, or upload to PC through U disk to generate WORD report.
     
        Convenient testing. The other tests are all based on the same wiring except for loading test.
     
        Easy to take, weight <9Kg.
     
        This product can be used with “CTPS1 large current generator”, it can output 150A current in maximum to carry out spot through-flow test.
  •  Device design can use in the following tests of CT&PT:

     
        Excitation characteristic testing
     
        Transformation ratio test
     
        Phase and polarity test
