Product Introduction:
Xsn-h02 frequency conversion type transformer comprehensive tester is a new generation of current and voltage transformer test instrument developed by the company after listening to users' opinions widely, after a lot of market research and in-depth theoretical research. The device adopts high-performance DSP and ARM, excellent manufacturing process, to ensure stable and reliable product performance, complete function, high degree of automation, high test efficiency, is a professional test instrument for transformer in the power industry.
Product features:
1, comprehensive functions, satisfy all kinds of CT (such as: protection, metering, TP) excitation characteristics (i.e., volt-ampere characteristics), variable ratio, polarity, the secondary winding resistance, secondary load, poor contrast and the Angle of test requirements, and can be used in all kinds of excitation characteristics of PT electromagnetic unit, strain ratio, polarity, secondary winding resistance, poor contrast and the Angle of test;
2. CT and PT parameters such as inflection point voltage/current, 10%(5%) error curve, accuracy limit coefficient (ALF), instrument security coefficient (FS), quadratic time constant (Ts), remanence coefficient (Kr), saturation and unsaturated inductance are given automatically;
3, the test meets GB1208 (IEC60044-1), GB16847(IEC60044-6), GB1207 and other kinds of transformer standards, and according to the type and level of transformer automatically choose which standard to test;
4. Based on the test principle of low-frequency method, it can deal with CT test of inflection point up to 45KV;
5, friendly and beautiful interface, full Chinese graphical interface;
6, the device can store 2000 groups of test data, power failure is not lost. After the test is finished, the U disk is stored in the PC, and the software is used for data analysis and WORD report is generated.
7, the test is simple and convenient, one click to complete THE CT direct resistance, excitation, variable ratio and polarity test, and in addition to the load test, all other CT tests are using the same wiring mode;
8, easy to carry, the weight of the device <9Kg.
