II. Characteristics
1.The tester is supplied with AC220V low voltage power to provide current for AB, BC and CA high voltage windings of the transformer automatically; collects data simultaneously and; calculates impedance error percentage automatically with intuitive testing results;
2.The tester completes the three-phase testing automatically in the primary connection mode other then inversed connection with the testing wire;
3. The tester allows either single phase testing or three-phase testing both manually and automatically;
4. The tester achieves output current limit applicable to test item with any impedance;
5. The test item can be measured without an external voltage regulator;
6.The tester functions in measuring zero sequence impedance;
7. The tester functions in measuring inductance;
8. The tester has a large LCD display with a menu in Chinese. Operation are facilitated based on the notes on the display; and
9.The tester enables printing and storage and is featured with high testing accuracy, high automation, small in size and light weight.
