Submarine power production installations use the power of the ocean to generate renewable energy for the population to use. To bring this electricity back to land, use of electrical cables is required. The choice of cable will affect both the quality of received power and the security of the transmission line. To find the inductance and capacitance of these submarine transmission lines, a study of the electric and magnetic fields that are produced due to the power flow on these cables must be performed. The armor that is used to protect the cable from underwater hazards is significant in determining the cable losses and finding the equivalent inductance and capacitance. Finding the inductance and capacitance of the submarine cable will allow for the determination of the two port parameters of the cable. These parameters will allow for the analysis of the transient and steady state performance of the cable.
