This paper describes the EMTP modeling method using searching coil test for HVDC submarine cables. HVDC submarine cables consist of conductor, lead sheath and amore. It is different from general cable which is composed with just conductor and aluminium sheath. Therefore, the transient characteristics are totally different between HVDC submarine cable and general cable. However, the study on HVDC cable modeling and transient are insufficient. In this paper, EMTP modeling is performed according to grounding interval and grounding resistance, then they are compared with real test results by searching coil test.
