FA-IV type CT volt ampere characteristic testerDetailed product description：

The FA-IV CT volt ampere characteristic tester is a fully automated PT and CT characteristic testing instrument. The tests that the instrument can complete include CT volt ampere characteristic test, PT volt ampere characteristic test, CT polarity test, PT polarity test, CT ratio polarity test, and PT ratio polarity test. It automatically calculates the error curve of CT at any point, CT/PT ratio difference and other result parameters.
Product features of CT volt ampere characteristic tester
1. Safe and convenient operation: The fully computerized device is equipped with an imported high-performance CPU, which has high reliability. After setting the test values according to the interface prompts, there is no need for manual contact with the tested equipment, saving tedious labor such as manual pressure adjustment, manual recording, organization, and curve drawing. Quick, simple, and convenient. No need for computer knowledge, easy to master, keeping test personnel away from high-voltage circuits and ensuring their personal safety.
2. Comprehensive functions: It can test and protect the volt ampere characteristics of CT, automatically draw 5% and 10% error curves, transformation ratio, polarity, and can also output high current for testing the secondary circuit of CT.
3. Large output capacity: The maximum output voltage for the volt ampere characteristic test is up to 1000V, the maximum current for the transformation ratio test is up to 600A, and the instrument output capacity is 5KVA.
4. Complete optional accessories: accessories include external booster, external current booster, and external voltage regulator. The maximum voltage of an external voltage booster can be increased to 2000V/3A, the external current booster can be increased to 1000A, and the maximum output of an external voltage regulator can reach 1500V/20A. When using an external voltage booster, the maximum voltage current characteristic test of a 500KV level 1A current transformer can be conducted.
5. Good human-machine interface: The large screen 320 * 240 dot matrix Chinese character graphic interface can directly display the volt ampere characteristic curve graph after testing is completed. The graph is clear, beautiful, and easy to analyze. It comes with a micro printer that can print the curve and test results at any time.
6. Convenient human-computer interaction: The instrument uses a high-performance photoelectric rotating mouse as an input device, which is easy to operate and has a long service life.
7. Large data storage capacity: The instrument is equipped with built-in Flash memory, which can store a large amount of experimental data. The data will not be lost after power failure. After the on-site test is completed, the test results can be viewed and printed indoors.
8. Multi channel human-computer interaction: In addition to using a rotating mouse for input control, the instrument can also be connected to a computer through its built-in RS232 communication interface to achieve communication between the PC and the instrument. Test personnel can use the computer to control the instrument for testing or upload test data from the instrument. The PC application software included in the instrument has powerful functions, beautiful appearance, simple operation, and can save and print test results. The test data can also be exported as an EXCEL format document for editing.
9. Convenient operation of test results: After the test, the voltage and current values corresponding to each point on the curve can be displayed through a cursor. Printing can choose to print data or print the curve, or both at the same time. The printing interval of data can also be set according to actual needs, and the type and label of saving can be set according to actual needs.
10. Multi power supply mode: The instrument power supply can achieve adaptive power supply of AC220V and AC380V. When the input terminal of the AC power supply is connected to AC220V voltage, the AC voltage output is 0-600V. When the input terminal is connected to AC380V voltage, the AC voltage output is 0-1000V. Users can choose according to their actual needs.

Safety precautions for CT volt ampere characteristic tester
1. The grounding terminal on the instrument panel should be reliably grounded during use.
2. When conducting the volt ampere characteristic test and automatic boost test, do not connect an external voltage regulator. (External regulator and external booster are not the same concept, please refer to the relevant sections of the manual)
The working power supply of the instrument is~220V or~380V, and the socket is installed on the side panel.
4. Do not block the fan vent on the side panel of the instrument to prevent overheating.
If the instrument is not used for a long time, please store it in a dry and ventilated place and power it on once a month
