VIEW OF MAIN HEADER AND CONNECTIONS which are connected to the stepdown transformer taps togive a voltage of 170, 320 or 440 for starting the convertersfrom the a. c. side. There are also three 400-kw, 2300/-22,000-volt transformers for the transmission line toClarksburg. INTERIOR VIEW OF CAR HOUSE busbar. As a rule the day load calls only for one looo-kwand one 500-kw unit, the second 500-kw going into servicein the evening. The regulation is all that can be expected,the variation in voltage on the secondaries not exceeding;two volts with the swing of the load.
