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
History and use of the single transferable vote percentage of the vote. In the Australian Senate elections, nearly 95% of voters use the group voting tickets instead of ranking their own preferences. As a result, the informal rate reduced from around 10 percent, to around three percent. STV-PR was used in the Calgary and Edmonton electoral districts (and Medicine Hat for the 1926 election only) for electing Members of the Alberta Legislative Assembly from 1926 to 1955, with five, six or seven MLAs being elected at-large in each city. All other electoral districts used instant-runoff voting Alternative Voting/preferential voting. In 1958 the cities were divided into many single-member
