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 by an independent Constituency Commission under terms of reference given by the Minister for the Environment. Elections from 1932 to 1987 resulted in either a single-party Fianna Fáil government or a coalition of two or more of the other parties. Since 1989, every government has been a coalition. From 1941 to 1965, the city councils of Cork, Limerick and Waterford were each elected in a single local electoral area (LEA), returning 21, 17, and 15 councillors respectively.
