Abstract	The largest 60-cycle transformer core ever made now is in successful operation on a 300,000,000-volt betatron. If this core were used for an oil immersed power transformer, windings for continuous operation at 2,000,000 kva could be placed on it. Construction of this core is a demonstration of the feasibility of constructing transformers many times as large as those now being built. The advantages of larger transformers are lower cost per kilovolt-ampere and less loss per kilovolt-ampere transformed resulting in higher efficiency. The present limitation in the size of transformers is shipping clearances. When transformers larger than those which can be shipped are needed, they can be constructed by assembling them in the field using construction and methods similar to those employed for this large core.
