TKVA-B variable frequency transformer comprehensive tester is based on the traditional transformer volt-ampere characteristic transformation ratio polarity comprehensive tester based on voltage regulator, booster, and current transformer, and listens to users' opinions widely
A new generation of innovative CT and PT test instruments developed after extensive market research and in-depth theoretical research. Using high-performance DSP and ARM, advanced manufacturing technology to ensure product performance
It can be stable and reliable, with complete functions, high degree of automation, high test efficiency, and a high level in the country. It is a professional test instrument for transformers in the power industry.
The frequency conversion type transformer comprehensive tester meets the following occasions:
1. Suitable for transformer calibration of electric power research institutes;
2. It is suitable for the factory calibration of transformer manufacturers;
3. Meet the preventive test of the power sector;
4. Meet the handover test of engineering units and panel enterprises.
1. Comprehensive functions, which not only meet the excitation characteristics (ie volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, and ratio difference of various CTs (such as protection, measurement, TP)
It can also be used to test the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference and angle difference of various PT electromagnetic units;
2. Inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation are automatically given and
CT and PT parameters such as unsaturated inductance;
3. Based on the advanced low-frequency method test principle, it can cope with CT test with an inflection point of up to 45kV;
4. Friendly and beautiful interface, all Chinese graphical interface;
5. The device can store 2000 sets of test data, which will not be lost after power failure. After the test is completed, save it in the PC with a U disk, analyze the data with the software, and generate a WORD report;
6. The test is simple and convenient. The direct resistance, excitation, transformation ratio and polarity test of CT can be completed with one key. In addition to the load test, all other CT tests use the same wiring method;
7. Easy to carry, the weight of the device is less than 9kg.
