This study examines conductive noise in long distance cables in a subsea environment. The inverters currently used in subsea plants generate conducted noise, which is the cause of damage and insulation failure of electric motor bearings. In particular, it is important to analyze the characteristics of transient voltages for different subsea temperature and pressure changes. To analyze the transient voltages, the effects of L, R, and C for different temperature and pressure changes were investigated. Among the analysis factors of L, R, and C, the capacitance C was identified as the factor that influences conductive noise the most. As a result, we analyzed the impact of the electrical components (L, R, and C) on the noise in the design stage of a long-distance cable, focusing on the variables of pressure, and presented the guidelines for designing a subsea plant model.
