Frequency conversion transformer comprehensive tester
The frequency conversion transformer comprehensive tester is a new generation of current and voltage transformer test equipment developed by our company after extensively listening to users' opinions, after a large number of market research, and in-depth theoretical research. The device uses high-performance DSP and ARM, and advanced manufacturing technology to ensure stable and reliable product performance, complete functions, high automation, high test efficiency, and a leading level in the country. It is a professional test instrument for transformers in the power industry.
1.1 Main technical features
★ Comprehensive functions, which not only meet the excitation characteristics （ie volt-ampere characteristics）, transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and angle 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 angular difference of various PT electromagnetic units.
★ The inflection point voltage/current, 10% （5%） error curve, accuracy limit factor （ALF）, instrument security factor （FS）, secondary time constant （Ts）, remanence factor （Kr）, saturation and CT and PT parameters such as unsaturated inductance.
★ The test meets various transformer standards such as GB1208 （IEC60044-1）, GB16847 （IEC60044-6）, GB1207, etc., and automatically selects which standard for testing according to the type and level of the transformer.
★ Based on the advanced low-frequency method test principle, it can deal with CT tests with an inflection point of up to 45KV.
★ Friendly and beautiful interface, all Chinese graphical interface.
★ 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.
★ The test is simple and convenient. The direct resistance, excitation, transformation ratio and polarity test of CT can be completed with one key. Besides the load test, all other CT tests use the same wiring method.
★ Easy to carry, the weight of the device is <9Kg.
