(a) Bottom view of the linear generator, where it can be seen how the stator windings are mounted against the hull. The hulls of the generators in the farm provide a low-impedance path to each other via the sea water. (b) The common ground path through the sea water via their grounding impedances, , which are dominated by the cable insulation impedance of the stator windings. The red line illustrates one possible path for and to build up. The cable insulation must be rated above this to withstand an electrical breakdown.
