| Abstract |
The connection method of CCPU has been changed from connection between sheath and grounding to connection between sheaths without grounding since 1997. In domestic, there is so many cases that cables circuits were installed before 1997, added in same route after that, operated as multi-connecting systems of CCPU in same route. This paper examine the problem of multi-connecting system by EMTP simulation, and presents methods to improve the system characteristics. |
