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-dealer platform systems. A key aspect of an SDP is that it merges information and services both within and across asset classes. An SDP will typically combine elements such as pricing, trading, research and technical analysis within each asset class, and then draw together multiple asset classes. Although in principle SDPs are applicable to all types of tradable security, they have so far been most widely used in OTC markets such as foreign exchange and fixed income.
