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.
