I. Introduction
GDKC-2000 Power Transformer On-load Tap Changer Analyzer is mainly applied to test transient time, transition waveform, transition resistance, synchronization status of three phase.
II. Test 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. Be 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. Make word report
9.800× 480 colorized LCD with touch screen and high speed printer
10. Store 1000 groups of data and also can be saved by USB flash disk
