- Abstract
- Sheath circulating current is increased in the change of sheath mutual impedance which
is caused by unbalanced cable system, and different secton length between joint boxes.
If excessive current flows in sheath, sheath loss which is reduced the transmission
capacity is produced. Recently, excessive sheath circulating current was partially
measured in underground cable systems of KEPCO. Accordingly, actual schemes to reduce
excessive sheath circulating current are urgently required for installed cable system as
well as newly-installing cable systems. This paper describes the relation analysis
of sheath circulating current and burying types. And also, various schemes to reduce
excessive circulating current using EMTP/ATPDraw and applicable schemes are proposed
through a detailed analysis regarding cable systems by considering various electrical
and environmental factors. It is evaluated that the proposed reduction schemes can be
effectivelyapplied to reduce the excessive sheath circulating current with the
minimized electrical problems. And reduction effect is proved with sheath circulating
current reduction equipment.
