2. It automatically measures single-phase and three-phase transformer ratios and calculates the ratio error.
3. The built-in three-phase signal source enables accurate measurements of various transformer types including Y/y, Y/d, D/y, D/d, ZN/y, ZN/d, rectifier, and traction transformers.
4. It identifies the connection group and polarity of the transformer, clearly displaying the vector relationship between the primary and secondary windings.
5. It automatically tracks the on-load tap changer position and indicates the current tap point, ensuring accurate voltage regulation.
6. It displays the primary and secondary voltage oscillograms and phase relationships, allowing for harmonic analysis to detect potential transformer issues.
7. It includes CT and PT ratio testing and polarity verification functions for comprehensive electrical diagnostics.
8. It features reliable automatic protection mechanisms to ensure safety under abnormal conditions.
9. Its small size and lightweight design enable fast and accurate testing in approximately 3 seconds per test.
10. It stores and prints all test results, with 128MB internal memory (expandable to 4GB) and support for USB data transfer and computer upload.
11. It offers a 5-inch true color touch screen, emWin GUI interface, and Chinese input options for easy navigation and operation.
12. It supports on-site printing via Bluetooth or serial printer for immediate documentation.
