HGY Transformer Ratio and Polarity Tester Main Features 1. Overview of HGY Transformer Ratio and Polarity Tester: The transformer ratio and polarity 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 of CT, CT/PT ratio error, and other result parameters. 2. The HGY transformer ratio and polarity tester has the following characteristics: 1. Multiple power supply modes: The instrument power supply can adapt to AC220V and AC380V. When the AC power input terminal is connected to AC220V, the AC voltage output is 0~600V; when connected to AC380V, the output is 0~1000V. Users can choose according to actual needs. 2. Large output capacity: The maximum output voltage for volt-ampere characteristic test is up to 1000V, the maximum current for ratio test is up to 600A, and the output capacity of the instrument is 5KVA. 3. Large data storage capacity: The instrument has a built-in Flash memory that can store a large amount of test data. The data is not lost after power-off. After field tests, the test results can be viewed and printed indoors. 4. Safe and convenient operation: Fully computerized device with built-in high-performance imported CPU, high reliability. After setting test values according to the interface prompts, there is no need for manual contact with the tested equipment, saving tedious labor such as manual voltage regulation, manual recording, sorting, and curve drawing. 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. 5. Comprehensive functions: It can test the volt-ampere characteristics of protection CT, automatically draw 5% and 10% error curves, ratio, and polarity, and can also output large current to test the secondary circuit of CT. It can test PT volt-ampere characteristics, ratio, and polarity. 6. 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 the current up to 1000A, and the external voltage regulator can output up to 1500V/20A. When using the external voltage booster, the volt-ampere characteristic test of 500KV class 1A current transformers can be performed. 7. Good human-machine interface: Large screen 320*240 dot matrix Chinese character graphic interface. After the test is completed, the volt-ampere characteristic curve can be directly displayed. The graphics are clear, beautiful, and easy to analyze. It comes with a micro printer that can print curves and test results at any time. 8. Convenient human-machine interaction: The instrument uses a high-performance optical rotary mouse as the input device, which is simple and convenient to operate and has a long service life. 9. Multi-channel human-machine interaction: In addition to the rotary mouse for input control, the instrument can also be connected to a computer through the 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, beautiful, and easy to operate. It can save and print test results and export test data to EXCEL format documents for editing. 10. Convenient operation of test results: After the test, the cursor can be used to display the voltage and current values corresponding to each point on the curve. Printing can choose to print data or curves or both simultaneously. The printing interval can also be set according to actual needs. The type and label of the saved data can be set according to actual needs. 3.
