Advantages of High-precision Measurement
1. Ratio measurement range: 1-10000. Error <0.2% for 1-1000, <0.5% for 1000-10000, and repeatability error <0.05%, ensuring accurate and reliable data that meets strict testing standards.
2. Phase angle measurement range: 0-360° with error <0.5°, vector group measurement covers 1-12 groups, accurately capturing the phase relationship between primary and secondary voltages to facilitate comprehensive evaluation of transformer performance.
3. Built-in sine wave generator with output test voltage distortion <1%, unaffected by power grid noise, ensuring stable and accurate measurement results in complex environments.
4. Supports excitation current measurement (0-200mA, error <1%), synchronously feeding back the transformer's excitation state and providing multi-dimensional data support for fault diagnosis.
|
Multi-scenario Adaptability
 | Compatible with various winding connection modes of three-phase transformers (DY, YD, DD, YY, ZN) and supports single-phase transformer testing, adapting to multiple types of equipment such as power transformers and voltage transformers. |
| Supports dual-standard testing (IEC & IEEE). IEC standard outputs line voltage ratio, while IEEE standard outputs winding turn ratio, meeting testing specifications of different regions and industries. |
| Equipped with tap changer position detection function. By setting the regulation rate, it can automatically match the standard ratio, accurately identify tap positions, and simplify the transformer tap calibration process. |
| Operating temperature range: 0-50℃, humidity <90%, adapting to complex environments such as outdoor and substations, balancing laboratory fixed testing and on-site mobile testing needs. |
