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
Single (football) has gone into the local equivalent of the 'end zone' after striking another player. The Sheffield Rules, a 19th-century code of football, also used the rouge as a secondary scoring method. The behind used in Australian rules football is similar in concept to the Canadian single (worth one point whereas goals are worth six), as is the point in Gaelic football (where goals that go into the net score three points but balls that go over the crossbar score one). Single (football) In Canadian football, a single (single point, or rouge), scoring one point, is awarded when the ball is
