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 Use Medical Device Reprocessing the Therapeutic Goods Administration (TGA). Prior to implementation of these requirements, hospital reprocessing of SUDs was common. Health Canada does not currently regulate reprocessed single-use devices or the third-party companies that are reprocessing these devices for Canadian hospitals. Whether or not to reprocess a single-use device is determined by the territorial and provincial health ministries as well as hospital boards. A number of provinces have adopted similar positions that allow for the reprocessing of SUDs if the third party reprocessor is regulated by the FDA. British Columbia issued a policy to its health authorities stating that by January 1, 2008,
