As in the small station, the principal circuits are simple, but it is easily seen that whenabout three hundred kilowatts are to be carried in the circuits and turned into high frequencycurrents, the problem must be handled with care. Some of the special, arrangements made touse this large amount of current safelyand efficiently may be of interest to thestudent. The closed oscillating circuit is of in-terest because of the size and constructionof its various elements. The discharger isof the rotating-disc type, and is directlyconnected to the shaft of the foundation upon which it rests is asolid block of concrete weighing aboutseven tons, supported by piles of insulat-ing co
