The performance of annular and toroidal split transformers operating in seawater will be compared by means of water-tank experiments and by flux mapping with a computers an equation will be developed for the preferred construction which will describe the coupling coefficient and transmission losses as a function of separation sea water conductivity and ndisorientation.

A split-transformer system is proposed to function as a non-contacting connector. It will couple - by means of a single magnetic circuit - data communications and 400 watts of electrical power across a variable clearance gap in the range of 0 to 0.4 cm. The data rate will be 100 Kb/s and 10 Kb/s in the forward and reverse directions respectively. The split-transformer will operate in air or in sea-water where it will have advantages, over conventional connectors, with respect to effects of corrosion and misalignment.
