“…There is a segment without power supply in the electrified railway, which is called the neutral section or phase-separation. Conventionally, locomotives' drivers have to cut off the main breaker (vacuum circuit breaker, VCB) so as to avoid transients such as overvoltage and let locomotives coast through the neutral section (Busco et al, 2003;Wang et al, 2011;Hee-Sang, Sung-Min, & Jae-Chul, 2012;Horinouchi, Tsukima, Tohya, & Sasao, 2004;Kosmac & Zunko, 1995). The main breaker will be reclosed while the traction systems and the auxiliary systems will restart after locomotive running into the Phase B leg.…”
