An oil immersed transformer—anotherinnovation which puts this apparatus onthe same footing with the best interrupter-less transformer construction of today. Two outfits in one cabinet—both Teslaand dArsonval windings are incorporatedinto this single apparatus, which gives theoperator complete range of all high fre-quency m
