Detailed Description


1. Automatic testing: according to the set test parameters, fully automatic test of CT volt-ampere characteristics data and automatic drawing of excitation characteristic curve; automatic test and calculation of CT transformation ratio.

2. Comes with a 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. Comes with a 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 modes: the host uses high-grade membrane key operation, and also has convenient communication interfaces (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 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 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. Has low-voltage output mode: in the field, there are quite a number of current transformers with relatively low test voltage. When doing volt-ampere characteristic tests, using the 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 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 the control of a single-chip microcomputer, and can automatically adjust the overcurrent and overvoltage protection values according to the settings of test parameters to ensure the safety of the tested equipment.
