| Abstract |
Frequent input and interception of the main circuit breaker(MCB) has caused various abnormal voltages in the main transformer and power conversion system of a Korean high-speed train called KTX-Sancheon. Although there are some precedencies about surge arresters, related to the relationship between incorporating insulation to surge arresters and the electric power quality of the industrial lines within systems of the electric railway, and the efficient power supply system configuration of the railroad dispatching divisions, there are no previous research on insulation cooperation to the EMU.
Therefore, in this paper, the mutual insulation cooperative relationship is studied as a method of eliminating the transient phenomena of the abnormal voltage generated in the feed and receiving parts of railway vehicles by investigating of the operation characteristics of surge arresters and spark gap(SG) applied to Korean high-speed railway vehicles (KTX-Sancheon). |
