1. Can test low voltage short-circuit impedance, which is small in size and light in weight., 2.The method of three-phase simultaneous test and separate phase test is used to test the transformer.
A transformer short circuit impedance tester is used to measure the short circuit impedance for main transformers of Level 35KV and above under site and laboratory conditions. The tester is exquisitely designed with superior performance. The state-of-the-art single-chip microcomputer testing technology and digital signal processing technology have been adopted for its internal design, and the data measured by it are accurate; while a 7-inch touch color LCD screen has been used for its external design, displaying the operation menu in Chinese with more convenient touch operation. Meanwhile, it is equipped with a thermal printer and has the function of storage, which is convenient for data printing and storage. Thus, the data to be exported can be transferred to the computer via USB. Moreover, the tester is small in volume and easy to use and carry at the site. Single-phase and three-phase tests can be conducted after inputting parameters into the tester and the percentage error of the transformer impedance will be calculated automatically with intuitive test results. It is an instrument to rapidly test whether the transformer winding is deformed or not at the site.

HYDR Transformer Short-Circuit Impedance Tester
Product Feature And Application
1. AC 220V low-voltage power supply is adopted for the tester which applies current to AB, BC, and CA windings of single-phase and three-phase transformers in manual and automatic modes. The tester can measure not only the percentage error of the transformer's short circuit impedance when compared with the nameplate impedance, but also the transformer's impedance, reactance resistance, and inductance, which is convenient for users to compare data with intuitive test results.
2. Both single-phase test and three-phase tests can be conducted by the tester; Both manual testing and automatic testing are allowed.
3. The three-phase test can be completed automatically without reversed test lines due to its one-time wiring;
4. Items to be tested can be measured without an external voltage regulator;
5. The tester can display not only the percentage error of impedance but also the applied voltage, applied current, measured power, short circuit impedance, inductive impedance of short circuit, winding inductance, voltage of short circuit impedance, and so on;
6. Zero-sequence impedance is suitable for transformers with neutral points in star wiring on the high-voltage side. Zero-sequence impedance, inductive zero-sequence impedance, resistance of zero sequence, and inductance of zero sequence can be measured simultaneously by the tester.
7. Internal power supply and external power supply can be adopted for the tester;
8. A 7-inch color touch LCD screen is internally installed in the tester with an operation menu for more convenient touch operation. Meanwhile, the tester is equipped with a mini-printer for real-time data printing;
9. The tester is provided with an RS232 interface and the test data can be transferred to the backend;
10. 100 test records can be stored in the tester with the test storage time as the index for data storage;
11. The tester is provided with a USB interface and the test data can be transferred to a USB flash disk;
12. The tester has the function of clocking and the time can be calibrated automatically;
