The ZXHQ-A+ Fully Automatic Transformer Comprehensive Tester requires only simple digital settings: set the rated parameters of the transformer. The instrument automatically records all data throughout the process and calculates and displays parameters such as the transformation ratio polarity and voltage-current characteristic curves, eliminating the need for tedious tasks such as changing wires, manual voltage adjustment, manual data recording, data organization, and curve plotting.
Using simple operation and wiring methods to measure transformers significantly reduces work intensity and improves efficiency, making it convenient to conduct transformer measurements on-site; quick, simple, and convenient.
Performance Features :
1. Voltage-Current Characteristic Testing: The maximum output voltage of the single unit reaches up to 2500V, making it suitable for voltage-current characteristic testing of 500kV-class 1A current transformers. Turns Ratio Testing: The maximum current output reaches up to 600A. The device's power output provides true voltage and current values, with waveforms being standard sine waves at a frequency of 50Hz; it can effectively simulate the actual state of the transformer, complying with national maintenance regulations. The voltage regulation resolution can be as low as 0.13V.
2. Can test CT/PT for: “volt-ampere characteristics,” “5%, 10%, and 15% error curves,” “turns ratio and polarity,” “phase angle error and ratio error,” “secondary direct resistance,” “secondary load,” “secondary circuit,” “secondary withstand voltage,” and demagnetization function.
3. Testing complies with IEC 61869-3:2011, IEC 61869-2:2011, and other transformer standards, and automatically selects the appropriate standard for testing based on the transformer type and grade.
4. The 7-inch color touchscreen includes a Chinese input method, allowing for the input of Chinese codes.
5. The interface is user-friendly and aesthetically pleasing, featuring a fully Chinese graphical interface. The panel includes a built-in printer, enabling the printing of curve diagrams and test data at any time.
6. Equipped with a large-capacity storage device, it can store 4,000 sets of test data, with data retained even in the event of a power outage.
7. After testing, data can be saved to a USB drive and analyzed using software on a computer, with the ability to generate a Word report.
8. Features online functionality, allowing the instrument to be controlled via a computer for testing.
9. Automatic calculation of inflection points; comprehensive data query, browsing, printing, and deletion functions; built-in date/time functionality.
10. All-in-one design, lightweight at only 26 kg, easy to carry, and suitable for mobile testing.
