. Electrical world. FIG. I.—REGUL.^TOR the generator voltage is raised or depressed on the feeder is deter-mined by the amount of secondary winding included in the feedercircuit. The windings of the regulator, being arranged similarly tothose of the usual transformer, are free from all appreciable react-ance, and the regulator does not, therefore, introduce a lagging cur-rent into the system, as is the case with apparatus which contain alarge amount of reactance, the presence of which is a necessary con-sequence of the principle of regulation. The control of the feeder by means of this regulator is of the sim-plest nature. Starting with the regulator in position of maximumboost, that is. with the dial switch turned to the extreme left as faras it will go, a continuous right-handed movement of the dial switch. is complete the whole secondary winding is again included in thefeeder, but now opposing the voltage of the generator. Thus by one continuous movement of the switch, covering two rev-olutions in one direction, the complete range between maximum boostand maximum depression of the feeder voltage is covered. At eitherend of this range the switch is automatically arrested, so that it isimpossible to turn it too far. The dial switch embodies a number of improvements, designed toovercome objections in other forms of apparatus intended for asimilar purpose. In the dial switch, the awkward combination ofsplit contact fingers and reactive shunt is avoided and the switch op-erates with a positive snap movement from step to step, regardlessof the manner in which the operating handle is manipulated. This isaccomplished by means of compression springs interposed betweenoperating handle and the traveling blade. An automatic bolt holds the switch on its contact point until thebolt is withdrawn by a
