Detailed Description
1. Automatic testing: according to the set test parameters, fully automatic testing of CT volt-ampere characteristics data and automatic drawing of excitation characteristic curve; automatic testing and calculation of CT transformation ratio.
2. Built-in large-screen graphic LCD, full Chinese menu interface, cursor prompts for operation, real-time display of test data and curves, automatic scaling of curve coordinates for clearer reading.
3. Built-in micro printer, can print CT volt-ampere characteristic test report, excitation characteristic curve and CT transformation ratio test report in real time.
4. Dual operation mode: the main unit adopts high-grade membrane key operation, and also has convenient communication interface (RS232 or USB), can be connected to a laptop for operation, making it more convenient to use.
5. Built-in super large capacity memory, can store 6400 sets of test data; can be uploaded to PC, using the random software developed by our company to automatically generate and edit typical test reports, convenient for technical management and archiving. 6. Flexible configuration: the built-in voltage booster can raise voltage to 1000V, external voltage booster can raise to 2000V; the current booster is external type, optional with different capacities, maximum output current can reach 1500A, meeting more CT test requirements.
7. Low voltage output mode: in the field, there are quite a number of current transformers with lower test voltage. When doing volt-ampere characteristic test, using low voltage output mode (maximum 300V) can significantly improve voltage adjustment fineness and improve measurement accuracy.
8. Can also be used for complete group transmission tests of protection: utilizing the advantage of large current output of external current booster, it is very convenient and practical to conduct complete group transmission tests on protection.
9. Electronic polarity discrimination, with audible and visual indication of test results, convenient and intuitive.
10. Comprehensive protection functions: this machine has overcurrent and overvoltage protection functions under the control of single-chip microcomputer, and can automatically adjust the overcurrent and overvoltage protection values according to the set test parameters to ensure the safety of the tested equipment.
