General information about ADTC-3000 Transformer Tap Changer Tester
ADTC-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 auto transformer.
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.
