Power supply for Texas exposition

Electric power is supplied to the Texas Centennial Central Exposition at Dallas, from 2 13,200-volt distribution stations on opposite sides of the grounds which feed 38 “load center” stations distributed throughout the exposition area, over an underground distribution system. From these “load center” stations, power is distributed to the load, which is chiefly lighting, at 120/208 volts. One of the 2 substations is shown below; it contains one 3,000-kva 3-phase transformer and one 1,500-kva 3-phase unit. A typical “load center” station is shown at the left; this particular station consists of 3 100-kva single-phase 2,400-volt transformers with associated equipment. Those attending the Institute´s South West District meeting to be held in Dallas October 26–28, may be interested to see these and other units of the distribution system on the centennial grounds.
