Analysis of temperature and energy characteristic of OF Cable

OF 케이블의 온도 및 에너지 특성 해석

This paper analyses the characteristic of temperature and energy of oil field cable in transient state such as lightning surge. For analysis in various conditions, many actual underground power cable systems are modeled using ATP These results are applied for the examination of temperature increase when the hitting of lightning surge are occurred. The inner part temperature of OF cable is analysed according to the various kinds of cable using the thermal model of transient state. The temperature increase of sheath and crossbonded lead by fault current is also analysed using IEC 60949.
