Single-phase generator The early generators for those single-phase traction networks are single-phase generators. Even with newer three-phase motors which were introduced to some modern trains, the single-phases transmission for traction networks survive their time and are still in use in many railways today. However, many traction power stations have replaced their generators over time to use three-phase generators and convert into single-phase for transmission. In the early development of hydroelectricity, single-phase generators played an important role in demonstrating the benefits of alternating current. In 1891, a 3,000 volts and 133 Hz single-phase generator of 100 horsepower was installed at Ames Hydroelectric Generating
A Single Man the production design is by the same team that designed AMC television's "Mad Men", which is set in the same era. "Mad Men" star Jon Hamm has an uncredited voice cameo as the cousin of George's partner, Jim. The actual house where the character George lives in the film was designed in 1948 by John Lautner, his first house after leaving Frank Lloyd Wright.
