GDKC-2000 On load tap changer ohmmeter analyzer
1.Introduction
On load tap changer analyzer GDKC-2000 is mainly applied to test transient time, transition waveform, transition resistance, synchronization status of three phase.
2.Test feature
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 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
