A Study of CT Development Applied Elastic Epoxy

탄성형 에폭시를 사용한 변류기 개발에 관한 연구

In this paper, we studied a accuracy for CT using elastic epoxy. According to industry development, the quality where also the electric material is various is demanded. Insulation material is widely used because epoxy is superior to electrical and mechanical property. Until now, the possibility where the crack will occur is high because epoxy used to electrical products had high hardness. If thermal expansion is different of two material, contraction of epoxy heavily transformed turns ratio of CT. Elastic epoxy absorbed in expansion and contraction of substance material by temperature. So we could design more exacted CT. We had elastic test of elastic epoxy and made CT using elastic epoxy. At the result, We obtained turns ratio of within 4% superior to existing CT.
