Other features of the station include the use of a newtype of flash-over-proof rotary converter rated at 500-kw. and insulated for 1200 volts, although now operatingat only 600 volts. Extra lightning protection was pro-vided by placing aluminum cell lightning arresters oneach of the two outgoing 600-volt lines as well as on thedirect-current bus. An endeavor was thus made to pro-vide a bypass for the lightning that will be sure to stopit before it enters the control equipment. Another feature is the method of connecting varioussections of the grid resistors by short pieces of bus. July 20, 1918 Electric Railway Journal 119 HORN GAPS WITHCHARGING RESISTANCE.

This method of con-struction saved considerable time in the original instal-lation by simplifying the soldering of the different con-nections. They will also be much easier to maintainthan cable connections. The drum controller which actuates the contactorsof the automatic control is of a new type having thespindle horizontal instead of vertical.
