변압기 사고 검출을 위한 진동신호 연구

A Study on the Vibration Signal for Detection of Power Transformer Failure

  • 발행 : 1995.11.18

초록

Recently, as power transformer capacity is getting larger, vibration noise of transformer would be large and unexpected failuare of transformer give enormous economic loses, So we aquaire vibration signal, which is maked from transformer windings, core that are airtight out box with in insulation oil, and out box. Also we are fixed rated voltage and changing load current, analyize frequency domain of each vibration signals.
