Summary: | 碩士 === 中原大學 === 電機工程研究所 === 81 === This paper studies the fault current distribution for a
transmission system with overhead lines and some sections of
underground cables. There were seldom studies to analyze the
influences of cable juntions to a global grounding network. In
this paper, we used an application of "Decoupled Method" [1,2]
to calculate the fault current distribution at the large scale
interconnection grounding network, meanwhile, discussed the
grounding current, division factor, and relative problems.
From the study results, shown that the several factors of
cable junction deserved to be taken into account for determin-
ing a reasonable division factors. The methods for increasing
the division factor and for enhancing grounding safety are
also simutaneously proposed here.
