Detailed Description
1. Automatic testing: based on the set test parameters, fully automatic testing of CT volt-ampere characteristics data and automatic plotting of excitation characteristic curves; automatic testing and calculation of CT transformation ratio.
2. 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 reports, excitation characteristic curves, and CT transformation ratio test reports in real time.
4. Dual operation modes: the main unit uses high-grade membrane key operation, and also has convenient communication interfaces (RS232 or USB) for connection to a laptop for operation, making it more convenient to use.
5. Built-in large-capacity memory, can store 6400 sets of test data; can be uploaded to a PC, using the random software developed by our company to automatically generate and edit typical test reports, facilitating technical management and archiving. 6. Flexible configuration: the built-in voltage booster can raise voltage up to 1000V, and an external voltage booster can raise it to 2000V; the current booster is external, and different capacities of current boosters can be selected, with maximum output current up to 1500A, meeting the test requirements of more CTs.
7. Low-voltage output mode: in the field, there are a considerable number of current transformers with relatively low test voltage. When performing volt-ampere characteristic tests, using the low-voltage output mode (maximum 300V) can significantly improve voltage adjustment fineness and measurement accuracy.
8. Can also be used for complete group transmission tests of protection: utilizing the advantage of large current output from the external current booster, it is very convenient and practical to perform 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 microcontroller control, which can automatically adjust the overcurrent and overvoltage protection values according to the set test parameters to ensure the safety of the equipment under test.
