Product Selling Point Introduction
- 1. Measurement of three-phase short-circuit impedance:
Display three-phase voltage, three-phase current, three-phase power; automatically calculate the percentage of impedance voltage converted to rated temperature and rated current of the transformer, and the percentage of error with the impedance of the nameplate.
2. Measurement of single-phase short-circuit impedance:
Measure the short-circuit impedance of a single-phase transformer.
3. Measurement of zero-sequence impedance:
The measurement of zero-sequence impedance is suitable for transformers with neutral point in star connection on the high voltage side.
4. It can be directly measured within the allowable measurement range of the instrument, and external voltage and current transformers can be connected outside the measurement range. The instrument can set the transformation ratio of the external voltage and current transformers, and directly display the applied voltage and current values.
5. The instrument adopts large-screen color high-resolution touch LCD, Chinese menu, Chinese prompts, and easy operation.
6. The instrument comes with a printer, which can print and display data.
7. Built-in non-power-down memory, can store 200 sets of measurement data.
8. The instrument is equipped with a U disk interface for accessing test data.
9. Permanent calendar, clock function, time calibration can be carried out.
10. The instrument has a wide measurement range, high precision and good stability; small size and light weight are convenient for measurement.
