연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Previous research results indicated that the designed current reduction device could effectively reduce the sheath circulating current and that its RDP protection device could shield it against both fault and lightning strokes. In this paper, cable impedance is analyzed using wavelet analysis and di...

  • In the previous paper, the authors designed the current reduction device to reduce the sheath circulating current, and also designed its protection device named as RDP (Reduction Device Protector). The test and simulation results indicated that the current reduction device could effectively reduce the sheath circulating current and the protection device could protect it from any damage by lightning.
  • The test and simulation results indicated that the current reduction device could effectively reduce the sheath circulating current and the protection device could protect it from any damage by lightning. In this paper, in order to evaluate their impacts to the operation of distance relay while the single line to ground fault occurred, the impedances of the underground power cable system with current reduction device and RDP were calculated and then these impedances were compared with impedances without current reduction device and RDP. Because of the saturation characteristics of the designed RDP, the current reduction device and RDP just slightly changed the cable impedance at the relay point.
  • The authors proposed several protection methods for the reduction device using RDP, and proved the superior protection effect of DKC and KDC for both cable faults and lightning strokes [3].
  • The reason for this is that the core of the reactor is saturated by the overcurrent. The saturation characteristic of the developed reactor is tested by the experiment, and the obtained results are applied in transient analysis.
