The Cause of CCPU's failure and Improved Configuration Method in Combined Transmission Lines
초록
The protection of underground cables against transient overvoltages resulting from lightning and other causes is important in cable-tine which is connected with overhead line and underground cable. This paper investigates the failure of CCPU(Cable covering Protection Unit) and presents improved configuration method of CCPU in underground cable system EMTP(Electromagnetic Transient Program) is used in order to study the overvoltages and modeling of components of the system such as overhead lines, underground cables, CCPUs and towers in presented.
