Siemens was awarded a contract to supply 12 3-car driverless sets for the Sydney Metro Western Sydney Airport Line. Due to the higher overhead line voltage of 25 kV 50 Hz AC, [4] [5] these trains will be part of the Inspiro High Capacity (Inspiro HC) family. The first trains are expected to enter service in 2026.

Robert Watson-Watt (1892–1973), Scotland – microwave radar; James Watt (1736–1819), Scotland – improved Steam engine; Thomas Wedgwood (1771–1805), UK – first (not permanent) photograph; Carl Auer von Welsbach (1858–1929), Austria – Gas mantle, ferrocerium; Jonas Wenström (1855–1893), Sweden – three-phase electrical power
As an example, a 250 kVA motor–generator operating at 300 ampere of full load current will require 1550 ampere of in-rush current during a re-closure after 5 seconds. This example used a fixed mounted flywheel sized to result in a 1 ⁄ 2 Hz per second slew rate. The motor–generator was a vertical type two-bearing machine with oil-bath ...
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form 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 ...
IPS/UPS—Integrated Power System/United Power System, consisting of Independent Power Systems of 12 countries bordering Russia and the Unified Power System of Russia; IRC—ISO / RTO Council (electricity) IROL—Interconnection Reliability Operating Limit (electricity) IRP—Integrated resource planning; IRR—Internal Rate of Return (finance)
It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings. It is possible to avoid the multiphase slip ring assembly, but there are problems with efficiency, cost and size. A better alternative is a brushless wound-rotor doubly fed electric machine. [12]
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
