GDKC-3000 Transformer Tap Changer Tester

GDKC-3000 Transformer Tap Changer Tester

General introduction

GDKC-3000 is suitable to test various tap changers and arc suppression coil switch.

Features

  • With high stable negative feedback constant current technology, current stability <0.1%.
  • All data can be obtained at one time, easy operation.
  • Suitable to test autotransformer.
  • Accurately measure Y type non-neutral point transformers.
  • Real waveform and data can be shown.It is important to show transient process of tap changer which is useful to analyze the tap changer.
  • When the inductance of winding is big, it will cause oscillation of waveform. This model use high current injection retest to avoid the problem.
  • Built-in printer, with memory to storage data up to 40groups.
