1. It is an instrument for measuring low-voltage short-circuit impedance of main transformers of 35KV and above under field and laboratory conditions. The instrument is small in size and light in weight.

2. The instrument adopts voltage and current synchronous AC sampling and signal digital processing technology internally, ensuring accurate measurement data.

3. The transformer short-circuit impedance tester adopts single-phase measurement mode. Only the low-voltage side needs to be short-circuited, while the non-tested phases on the high-voltage side do not need to be short-circuited. After selecting the transformer connection, three measurements can automatically calculate the short-circuit impedance of each phase.

4. The instrument has the function of automatically converting low current test to rated current, suitable for field use.

5. The instrument can simultaneously measure voltage, current, and power, and also measure the frequency of the applied power supply.

6. The instrument can automatically or manually record the applied voltage and current. After completing three-phase measurement, it can automatically calculate the short-circuit impedance of each phase.

7. The transformer short-circuit impedance tester is equipped with a non-volatile memory that can store measurement data for a long time, and the instrument comes with a built-in printer.

8. The transformer short-circuit impedance tester features a large-screen LCD display with all Chinese menus and operation prompts, making operation simple and intuitive.
