They are cooled by an air blast as atNiagara. From the Buffalo transformer house the 370-voltthree phase current is fed to two 500-horse-power rotarytransformers (shown in Figure 3), which feed into the rail-way bus bars at 500 volts. These converters may be startedeither by the alternating current from Niagara or the directcurrent from the railway bus bars. The lightning arresters are of the Wirt non-arcing cylin-der type. They consist of strips of marble on which aremounted eleven cylinders, giving an air gap space of ^V inchfor each 1,000 volts, with allowance for 25 per cent ris
