32-518: After restoration of the Issaquah Depot neared completion in 1989, a group of Issaquah Historical Society members considered options for active use of the tracks leading to and from the restored depot. Discussions included dinner trains, passenger trains and eventually led to the easier to manage streetcar option. In 2001–02, a trolley car borrowed from Yakima Valley Trolleys was operated along existing, former-freight railroad track to prove

64-425: A reciprocating engine , with fuels mentioned above. This can be a steam engine , such as most coal-powered fossil-fuel power plants use. Some engine–generators use a turbine as the engine, such as the industrial gas turbines used in peaking power plants and the microturbines used in some hybrid electric buses . The generator voltage (volts), frequency (Hz) and power (watts) ratings are selected to suit

96-422: A transfer switch to disconnect the load from the utility power source when there is a power failure and connect it to the generator. Engine–generators are available in a wide range of power ratings. These include small, hand-portable units that can supply several hundred watts of power, hand- cart mounted units that can supply several thousand watts and stationary or trailer -mounted units that can supply over

128-631: A circuit breaker. Camlock connectors are rated for 400 amps up to 480-volt systems and used with 4/0 type W cable connecting to the generator. Tie-in panel designs are common between 200- and 3000-amp applications. Standby electrical generators are permanently installed and used to immediately provide electricity to critical loads during temporary interruptions of the utility power supply. Hospitals, communications service installations, data processing centers, sewage pumping stations, and many other important facilities are equipped with standby power generators. Some standby power generators can automatically detect

160-483: A constant engine speed regulator (governor) in diesel and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor; very large units may start with compressed air supplied either to an air driven starter motor or introduced directly to the engine cylinders to initiate engine rotation. Standby power generating units often include an automatic starting system and

192-465: A diesel- or gasoline-powered generator, users should make sure that the main breaker is in the "off" position, to ensure that the electric current does not reverse. Exhausting extremely hot flue gases from gen-sets can be done by factory-built positive pressure chimneys (certified to UL 103 test standard) or general utility schedule 40 black iron pipe. It is recommended to use insulation to reduce pipe skin temperature and reduce excessive heat gain into

224-454: A million watts. Regardless of the size, generators may run on gasoline , diesel , natural gas , propane , bio-diesel , water , sewage gas or hydrogen . Most of the smaller units are built to use gasoline (petrol) as a fuel, and the larger ones have various fuel types, including diesel, natural gas and propane (liquid or gas). Some engines may also operate on diesel and gas simultaneously ( bi-fuel operation ). Many engine–generators use

256-440: A portable generator. Trailer-mounted generators or mobile generators, diesel generators are also used for emergencies or backup where either a redundant system is required or no generator is on-site. To make the hookup faster and safer, a tie-in panel is frequently installed near the building switchgear that contains connectors such as camlocks. The tie-in panel may also contain a phase rotation indicator (for 3-phase systems) and

288-577: A shutdown caused by an unplanned power outage. For example, a hospital is in constant need of electricity, because several life-preserving medical devices run on electricity, like ventilators. A very common use is a railway diesel electric locomotive , some units having over 4,000 hp (2,983 kW). Large generators are also used on board ships that utilize a diesel-electric powertrain. Voltages and frequencies may vary in different installations. Engine–generators are used to provide electrical power in areas where utility (central station) electricity

320-406: A single piece of equipment. This combination is also called an engine–generator set or a gen-set . In many contexts, the engine is taken for granted and the combined unit is simply called a generator . An engine–generator may be a fixed installation, part of a vehicle, or made small enough to be portable. In addition to the engine and generator, engine–generators generally include a fuel supply,

352-683: A small covered platform at the end of the line adjacent to the Issaquah Chamber of Commerce building, which have would be allowed the trolley to serve the purpose of an actual (though limited) transit system, ferrying riders between Issaquah's downtown (accessed from the Issaquah Depot) and the Issaquah commercial core's other major pedestrian destinations: Confluence Park and the Gilman Village shopping district (accessed from

384-681: Is 50 feet (15.2 m) long, with a capacity to store just one trolley (and its towed generator). IVT sometimes refers to it as the "display building", because glass windows on its west side allow the public to see the trolley car inside. After returning the borrowed trolley to Yakima in May 2002, Issaquah acquired three trolleys of its own: an ex- Milan interurban car (No. 96) from the San Francisco Municipal Transportation Agency , and two narrow gauge ex- Lisbon trolleys (Nos. 519 and 521, originally built by

416-616: Is 60 Hz such as in North America, generators rotate at 1,800 rpm or another divisor of 3600. Diesel engine–generator sets operated at their peak efficiency point can produce between 3 and 4 kilowatt hours of electrical energy for each liter of diesel fuel consumed, with lower efficiency at partial loads. Many generators produce enough kilowatts to power anything from a business to a full-sized hospital. These units are particularly useful in providing backup power solutions for companies which have serious economic costs associated with

448-509: Is a 100 kVA set which produces 415 V at around 110 A . It is powered by a 6.7-liter turbocharged Perkins Phaser 1000 Series engine, and consumes approximately 27 liters of fuel an hour, on a 400-liter tank. Diesel engines in the UK can run on red diesel and rotate at 1,500 or 3,000 rpm. This produces power at 50 Hz, which is the frequency used in Europe . In regions where the frequency

480-458: Is necessary, thus reducing the noise of the engine and making it more fuel-efficient. Inverter generators are best to power sensitive electronic devices such as computers and lights that use a ballast, as they have a low total harmonic distortion . Since the load on the electric generator causes the speed of the engine to fall, this has an adverse effect on the frequency and voltage of the electrical output. By using an electronic inverter to produce

512-431: Is unavailable, or where electricity is only needed temporarily. Small generators are sometimes used to provide electricity to power tools at construction sites. Trailer-mounted generators supply temporary installations of lighting, sound amplification systems, amusement rides, etc. A wattage chart can be used to calculate the estimated power usage for different types of equipment to determine how many watts are necessary for

544-563: The J. G. Brill Company and assembled in Lisbon in 1925) from a failed plan for a trolley line in Aspen, Colorado . None was able to operate, as they all needed restoration work before being usable for service, and the ex-Lisbon trolleys also required " re-gauging " from 900 mm ( 2 ft  11 + 7 ⁄ 16  in ) gauge to 4 ft  8 + 1 ⁄ 2  in ( 1,435 mm ) standard gauge to enable them to run on

576-638: The Lake Sammamish rail-trail , as far as the boat-launch , were dashed upon removal of rail equipment and completion of the East Lake Sammamish Trail in 2006. In autumn 2020, amid the COVID-19 pandemic , Issaquah History Museums announced that it had decided to discontinue operation of the streetcar permanently, citing increasing insurance costs and other factors that had raised the cost of operation, in combination with cuts to

608-577: The Seattle, Lake Shore and Eastern Railway Depot , is a former railway station located in Issaquah , Washington , listed on the National Register of Historic Places . It was built in 1889 as a passenger station and freight warehouse for the Seattle, Lake Shore and Eastern Railway (SLS&E), serving what was then known as Gilman, Washington (and as Squak Valley until 1888). The town

640-453: The bridge could not be used until repair work on the bridge. By 2016, rehabilitation work on the bridge had been completed, allowing the route to be extended across and beyond the bridge, to Gilman Blvd., where the track ends. The extended line came into use at the beginning of the 2016 season, on May 7, making the overall length of usable track about 0.6 miles (1 km) long. Before the line's closure in 2020, future plans had included building

672-534: The concept that an operating trolley in Issaquah would attract ridership. The borrowed streetcar had arrived in Issaquah in October 2000, and began carrying passengers on May 19, 2001, with the service operating on Saturdays and Sundays from 11:00 a.m. to 3:00 p.m. through the summer and again in spring 2002. In spring 2001, a small carbarn to house the trolley car was built adjacent to the Issaquah Depot. It

736-666: The existing railroad track in Issaquah. In March 2012, one of the ex-Lisbon cars, No. 519, was sent to the Gomaco Trolley Company , in Iowa , for restoration and re-gauging of its truck . The car returned from Gomaco in August, its restoration completed, and made a test run over the line. with additional crew training then following. It entered service in Issaquah on October 14, 2012. As part of its payment to Gomaco for restoration of car 519, IVT transferred ownership of

768-455: The load that will be connected. Portable engine–generators may require an external power conditioner to safely operate some types of electronic equipment. Engine-driven generators fueled on natural gas fuel often form the heart of small-scale (less than 1,000 kW) combined heat and power installations. There are only a few portable three-phase generator models available in the US. Most of

800-537: The loss of grid power, start the motor, run using fuel from a natural gas line, detect when grid power is restored, and then turn itself off—with no human interaction. Privately owned generators are especially popular in areas where grid power is undependable or unavailable. Trailer-mounted generators can be towed to disaster areas where grid power has been temporarily disrupted. Every year, incorrectly used portable generators result in deaths from carbon monoxide poisoning . A 5.5 kW portable generator will generate

832-515: The new Gilman Station). The trolley towed a generator car to supply its traction motors with electricity, rather than receiving power from overhead wires . The museum also has an operational 0-4-0 Plymouth gasoline-mechanical locomotive for use as a rescue vehicle if the trolley were to fail mid-trip. 47°31′52″N 122°02′08″W  /  47.53111°N 122.03556°W  / 47.53111; -122.03556 Issaquah Depot Issaquah station , also known as Issaquah Depot or

864-522: The organization's financial resources. Public service began on October 14, 2012, with initial hours of operation scheduled for weekends from 11 a.m. to 3 p.m. until sometime in November. The section of railroad line brought into use for rides at that time was about one-half-mile (0.80 km) long, stopping just before the bridge over the East Fork of Issaquah Creek. The section of the track north of

896-763: The other Lisbon car, No. 521, to Gomaco. The car was shipped to Gomaco in August 2012, and Gomaco began a heavy restoration of it as an internal project. By that time, IVT had dropped all plans to use the 1930-built ex-Milan car No. 96 and put it up for sale. The car was sold in 2015 to the Oregon Electric Railway Historical Society and was transported to the Oregon Electric Railway Museum in December 2016. The IVT group's original hopes to rebuild one to two miles (3.2 km) of recently removed track on

928-399: The portable units available are single-phase generators and most of the three-phase generators manufactured are large industrial type generators. In other countries where three-phase power is more common in households, portable generators are available from a few kW and upwards. Small portable generators may use an inverter . Inverter models can run at slower RPMs to generate the power that

960-601: The required AC output, its voltage and frequency can be stable over the power range of the generator. Another advantage is that the generated electric power from the engine-driven generator can be a polyphase output at a higher frequency and at a waveform more suitable for rectification to produce the DC to feed the inverter. This reduces the weight and size of the unit. A typical modern inverter–generator produces 3kVA and weighs ~ 26 kg making it convenient for handling by one person. The mid-size stationary engine–generator pictured here

992-442: The same amount of carbon monoxide as six cars, which can quickly build up to fatal levels if the generator has been placed indoors. Using portable generators in garages, or near open windows or air conditioning vents can also result in carbon monoxide poisoning. Additionally, it is important to prevent backfeeding when using a portable engine generator, which can harm utility workers or people in other buildings. Before turning on
