Transformer With Load Switch Tester

Transformer load switch tester is integrated testing device, it's used for measuring and analyzing the power transformers and special transformers with load switch electrical performance. It adopts microcomputer control through the precision designed measuring circuit, which can realize on-load switch transition time, transition waveform , transition resistance , three-phase simultaneous and other parameters measured accurately. Users may need and site conditions , leads directly from the tap to measure , but also by the three-phase transformer casing and wiring direct measurement of the neutral point . Based on user need and on-site condition, it can measure directly via a tap switch lead, and also can measure though transformer three-phase drivepipe and neutral point directly.

Product Features:

 

1.Testing Y0 Y △type transformers,resistance will be displayed directly without conversion;
2.Data analysis humanized, can identify the trouble among the waveform automatically, and making marks;
3.Waveform display is based on data back to automatically adjust the sampling time and the magnitude of the resistance;
4. Can test with winding or without;
5. Four-terminal connect wire method,provide high-precision resistance to measure,without wire compensation;
6.Can test continuously in the process of be testing,saving transformer outage time;
7.Instrument can generate word report to facilitate data management and query;
8.YZ-2008 transformer load switch tester is controlled by a small computer, outside with a 800 × 480 color LCD touch screen , high-speed thermal printer, support external keyboard and mouse , easy to operate;
9.Instrument's internal can save 800 sets of data automatically, or can be saved by U disk.
