I. Introduction:
The on load tap changer analyzer can record switch operation waveform in overall process. The longest time is 6.4s.It can test various parameters such as transition waveform, transition time, transition resistance and three phase synchronization one time and analyze results automatically. It has power-off protection, over-voltage protection, perpetual clock and high-speed printing.
II.Main Features
1. Test transformers of type Y0 Y Δ and display resistance value directly;
2. Automatically analyze waveform fault and mark the fault;
3. Automatically adjust resistance value and time range according to sampling data;
4.Transformer type Δ is able to display to synchronization status of three phase;
5. It is able to test with winding or without winding;
6. Four terminal connection mode and provide high accuracy of resistance measurement.
7. Continuous test to save time of power off
8. This on load tap changer analyzer can produce word report
9. 800×480 colorized LCD with touch screen and high speed printer are designed with OLTC on load tap changer analyzer.
10. Store 1000 groups of data and also can be saved by USB flash disk.
