HVDC 케이블용 XLPE 절연 재료에 대한 DC/Impulse 중첩실험 시스템 구축

Build-up of DC/Impulse Superposition Testing System for XLPE materials in HVDC cables

In this study, in order to develop the evaluation method for XLPE materials for HVDC cables, DC/Impulse superposition testing system was builded up. Throughout the P-spice simulation, optimal values of the protection resistor for the DC generation system and the blocking capacitor for the Impulse generator were calculated. DC/Impulse superposition system showed good result maintaining their proper wave shapes and amplitudes. This system would be planned to apply to the evaluation of XLPE materials for HVDC cables.
