Studies on treeing phenomena have depended on the visual measurement using optical microscope. In the visual measurement, it is difficult to analyze the treeing in real time because voltages are applied discontinuously and impossible to calculate the deterioated area by treeing. Only tree type and length are studied. In this paper, image processing is introduced and voltages are applied continuously. The tree length and area are calculated in real time from tree inception to breakdown. Growing characteristics about tree types are compared for the normalized breakdown time.

In this paper, a system to measure treeing degradation phenomena in organic insulating materials, using an image sensor, is discussed. Using an image processing technique, tree features immediately after tree initiation as well as changes in the configuration of the tree were measured. which up to now have been extremely difficult to observe by conventional visual methods. As a result, it was possible to record the image of tree propagation immediately after its first appearance, and to describe the specific characteristics of tree growth in terms of the length, the degraded area and the sequential images.

오늘날 현대사회는 인터넷의 보급으로 지식정보화사회로 급속도로 변화하고 있다. 이전 대량생산시대와는 달리 소비자들의 욕구와 기호는 매우 다양하게 형성되고 있다. 여러 기업들이 생산하는 제품들도 대부분 시기와 계절에 따라 생산율과 판매율이 달라지고 있는 실정이다. 제품들의 생산 및 원가산출, 적정재고량 파악을 위해 기업들은 BOM(Bill of Material)을 작성하여 관리하고 있다. 하지만, 다양하게 변화하는 현대사회에 요구사항을 반영하지 못하고 여러 문제점들을 야기하고 있다. 본 논문에서는 원자재 공급업체에서부터 판매회사까지의 자동발주시스템을 완성하여 보고자 한다.
