Description
This device applies to measure and analyze loading tap switch property index of power transformer and special transformer. It is controlled by computer; using special loops to test the transition time, transiting wave, transition resistance, and three-phase synchronism of tap switch, etc.
Features
1. Test Y0 Y △type transformer, display the resistance without conversion.2. Data analysis of human nature, you can automatically identify the fault in the middle of the waveform, and make a mark;
3. Waveform display is automatically adjusted according to the sampling data and the resistance to the magnitude of the time;
4. The △ type transformer can display the three-phase synchronization;
5. The test can be carried out with or without winding;
6. There are four terminal connection modes, to provide high precision resistance measurement, and no need to wire compensation.
