Transformer volt-ampere characteristic curve characteristic tester is specifically designed for testing transformers: volt-ampere characteristic curve characteristics, transformation ratio, positive and negative electrodes, secondary winding internal resistance, load, angle difference, ratio difference and other basic parameters And the designed multi-purpose field test equipment. The transformer tester tests the CT/PT volt-ampere characteristic curve and the 10% error value curve according to the frequency conversion method. The output is only 180V AC voltage and 12A AC current, but it can cope with CT tests with an inflection point of up to 30kV.

 

      Comprehensive tester for transformer characteristics

      This instrument has the following internal structure and features:

 

      1. The transformer tester can detect and calculate CT and PT according to different specifications such as GB1208-2006 (IEC60044-1) and GB16847-1997 (IEC60044-6).

      2. Use frequency conversion method to detect CT/PT volt-ampere performance curve and 10% error curve, export only 180V AC voltage and 12A AC current, which can solve the CT detection with the inflection point of the function as high as 30kV.

      3. In all aspects of basic functions, various types of CT and PT excitation regulators, transformation ratio, phase, polarity, secondary winding resistance, load, ratio difference and angle difference can be used to detect steady-state or transient performance.

      4. Automatically obtain the function's inflection point voltage/current, 10% error curve, 5% error curve, accuracy limit factor (ALF), instrument panel security factor (FS), quadratic time constant (Ts), remanence coefficient (Kr), accuracy level, saturation and unsaturated inductance and other parameters.

      5. The instrument operation panel is friendly and beautiful, the Chinese version is graphical, and the 5.7-inch graphical transflective LCD is visible in the sun.

      6. The instrument uses a rotating optical mouse for operation, which is simple, fast and convenient, and easy to master.
