On Load Tap Changer Analyzer HYKC-2000
Introduction
On load tap changer analyzer HYKC-2000 is a comprehensive measuring instrument for measuring and analyzing the electrical performance indicators of on-load tap-changers for power transformers and special transformers in power systems, which is mainly applied to test transient time, transition waveform, transition resistance, synchronization status of three phase.
Major testing items and functions
1. Test transformers of type Y0 Y △ 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 △ is able to display synchronization status of three phase.
5. Be able to test with winding or without winding.
6. With 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 , which can also be saved by USB flash disk
