Short circuit impedance is an important parameter of transformers, and the short-circuit impedance method is a traditional method for determining winding deformation

1. Can measure transformer short-circuit impedance, short-circuit reactance, three-phase impedance voltage;

2. Can display parameters such as voltage, current, power, frequency, etc. for each test;

3. Measurement can be completed using only single-phase 220V AC power supply. In the absence of AC power supply, low-power UPS power supply (online 500VA is sufficient) can be used for power supply;

4. The test power supply can choose between internal power supply and external power supply: the internal power supply is the working power supply of the instrument, and the external power supply can be input by a voltage regulator;

5. The wiring operation is simple and convenient. With one wiring and one start-up, the three-phase measurement can be automatically completed and the measurement results can be directly displayed;

6. When using an internal power supply, the output voltage and current are automatically controlled internally, without the need for any external auxiliary equipment;

7. Automatic frequency correction can eliminate errors caused by frequency fluctuations;

8. This instrument can store thousands of measurement results and has a built-in power on memory that can store measurement data for a long time;

9. Large screen LCD display;

10. Calendar and clock functions without power failure.
