| HGY Transformer Characteristics Comprehensive Tester |
HGY Transformer Characteristics Comprehensive 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 and polarity test, and PT ratio and polarity test. It automatically calculates the error curve at any point for CT, and parameters such as CT/PT ratio error. The instrument has the following characteristics:
1. Safe and convenient operation: Fully computerized device, built-in imported high-performance CPU, high reliability. After setting test values according to the interface prompts, there is no need for manual contact with the tested equipment, eliminating tedious tasks such as manual voltage adjustment, manual recording, sorting, and curve plotting. Fast, simple, and convenient. No computer knowledge required, extremely easy to master, keeping test personnel away from high-voltage circuits and ensuring their personal safety.
2. Comprehensive functions: Can test protection CT volt-ampere characteristics, automatically plot 5% and 10% error curves, ratio, polarity, and can also output large current for testing CT secondary circuits. Can test PT volt-ampere characteristics, ratio, and polarity.
3. Large output capacity: The maximum output voltage for volt-ampere characteristic test is up to 1000V, and the maximum current for ratio test is up to 600A. The instrument output capacity is 5KVA.
4. Complete optional accessories: Accessories include external voltage booster, external current booster, and external voltage regulator. The external voltage booster can raise the voltage up to 2000V/3A, the external current booster can raise to 1000A, and the external voltage regulator has a maximum output of 1500V/20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers of up to 500KV class with 1A rating.
5. Good human-machine interface: Large 320*240 dot matrix Chinese character graphical interface. After testing, the volt-ampere characteristic curve can be directly displayed. The graphics are clear, beautiful, and easy to analyze. It comes with a built-in micro printer, allowing curves and test results to be printed at any time.
6. Convenient human-machine interaction: The instrument uses a high-performance optical rotary mouse as the input device, making operation simple and convenient with a long service life.
7. Large data storage capacity: The instrument has a built-in Flash memory that can store a large amount of test data. Data is not lost after power-off. After completing field tests, test results can be viewed and printed indoors.
8. Multi-channel human-machine interaction: In addition to using the rotary mouse for input control, the instrument can also be connected to a computer via its built-in RS232 communication interface, enabling 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 provided with the instrument is powerful, aesthetically pleasing, and easy to operate. It can save and print test results and export test data to EXCEL format for editing.
9. Convenient test result operation: After testing, the cursor can be used to display the voltage and current values corresponding to each point on the curve. Printing options include printing data, printing curves, or both simultaneously. The data printing interval can also be set according to actual needs. Saving can be customized with the type and label according to actual requirements.
10. Multiple power supply modes: The instrument power supply supports adaptive AC220V and AC380V. When the AC power input terminal is connected to AC220V, the AC voltage output is 0~600V. When the input terminal is connected to AC380V, the AC voltage output is 0~1000V. Users can choose according to actual needs.
