Abstract

Selection and application recommendations of lightning arresters for DC electric traction vehicles are presented. To decide arrester specification such as continuous operating voltage(COV, $U_c$), rated voltage($U_R$), and nominal discharge current($I_n$), variations of system voltage and surge currents flowing arresters were analyzed in running-service of traction vehicles. System voltages increased up to 1,800V during anti-breaking. Surge currents recorded 3 times per running-service-route and their magnitudes were ranges of $150A{\sim}2kA$. From the field measurement and consideration of EN50163, COV, $U_c$, and $U_R$ for the $1,500V_{DC}$ traction vehicles were proposed.
