This instrument volt-ampere characteristics, transformation ratio, and polarity comprehensive tester is designed for the professional test of current transformer volt-ampere characteristics, transformation ratio testing and differentiation of relay protection. It can also be used as a transformer polarity discrimination test. A multifunctional tester with a high performance-to-price ratio.

 

      This equipment uses high-efficiency, low-consumption, high-quality materials and a high-voltage booster with a special winding method. The microcontroller carries out data collection, analysis and storage. The built-in micro-printer can print test data information and graphs. When measuring the CT ratio, it can be Automatically calculate the ratio of transformation. One person can do all the testing work. The device is light in weight, portable, and convenient in actual operation. With its unique characteristics, it is a rare instrument and equipment at this stage.

 

      This product has the following features:

 

      1. Only need to set the detection working voltage, working current and step width, the equipment will automatically transform the voltage and draw the volt-ampere performance detection curve diagram automatically, saving manual adjustment, manpower record query, drawing curve diagram and other tedious labor . Convenient, simple and convenient.

     

      2. Fool-style wiring method, all CT/PT experiments can be realized with only 6 wiring heads.

 

      3. It can detect CT/PT volt-ampere performance, transformation ratio and polarity, CT5% and 10% error graphs, CT secondary side control loop, and AC withstand voltage test.

 

      4. If the output voltage of a single unit cannot meet the needs, an external high-voltage booster can also be used for testing. Volt-ampere performance experiment output voltage 0-1000V, working current 0-20A; use external high voltage booster output voltage 0-2500V, working current 0-1.5A, can do 500KV class 1A voltage transformer volt-ampere performance test.

 

      5. Contains a large-capacity memory, which can store 45 groups of test data, which will not be lost after power failure.
