Transformer tap-changer on-load-transition resistance tester
Product characteristics
1, test Y0, Y, △ type transformer, resistance value without conversion directly display.
2. Humanized data analysis can automatically find out the fault in the middle of the waveform and make a mark.
3, waveform display is based on the sampled data automatically adjust the resistance value and time amplitude.
4, can be tested with winding or without winding.
5, four-terminal wiring, providing high-precision resistance measurement, and no wire compensation.
6, in the middle of the test can be continuous test, saving the transformer power failure time.
7, the transformer on-load switch tester can generate word report, convenient data management and query.
8, the instrument is controlled by a small computer, equipped with 800×480 color LCD touch screen.
9, high-speed printer, support external mouse, easy to operate.
10, the instrument can automatically save 1000 sets of data inside, and can also be stored with external U disk.
