Product Details

The HGY Transformer Characteristics Comprehensive Tester is a fully automated PT and CT characteristic testing instrument. The tests that can be performed 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 at any point for CT, and parameters such as CT/PT ratio error. The instrument has the following features:

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. It is fast, simple, and convenient. No computer knowledge is required, and it is very 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, and polarity. It can also output large currents for testing CT secondary circuits. It can test PT volt-ampere characteristics, ratio polarity, and polarity.

3. Large output capacity: The maximum output voltage for volt-ampere characteristic tests is up to 1000V, and the maximum current for ratio tests is up to 600A. The instrument's 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 increase voltage up to 2000V/3A, the external current booster can increase current up to 1000A, and the external voltage regulator can output up to 1500V/20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers up to 500KV class 1A.

5. Good human-machine interface: Large 320*240 dot matrix Chinese character graphical interface. After testing, the volt-ampere characteristic curve can be displayed directly. The graphics are clear, beautiful, and easy to analyze. It comes with a built-in micro printer that can print curves and test results 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 built-in Flash memory that can store a large amount of test data. Data is not lost after power-off. After on-site testing, test results can be viewed and printed indoors.

8. Multi-channel human-machine interaction: In addition to input control via the rotary mouse, the instrument can also be connected to a computer via 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 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 be set according to actual needs, and the type and label of saved data can be set as required.

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.
