A specific model of a generator operated as a standby generator may only need to operate for a few hours per year, but the same model operated as a prime power generator must operate continuously. When running, the standby generator may be operated with a specified - e.g. 10% overload that can be tolerated for the expected short running time.
Carousell was founded in Singapore on 14 May 2012, by co-founders Quek Siu Rui, Lucas Ngoo, and Marcus Tan. The first item sold on Carousell was an Amazon Kindle e-reader for S$75. [1] Carousell was subsequently registered as Carousell Pte. Ltd. on 2 January 2013. [2] Carousell received its first investment from Quest Ventures. [3]
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 ...
Microturbines have around 15% efficiencies without a recuperator, 20 to 30% with one and they can reach 85% combined thermal-electrical efficiency in cogeneration. [2] The recuperated Niigata Power Systems 300 kW (400 hp) RGT3R thermal efficiency reaches 32.5% while the 360 kW (480 hp) non recuperated RGT3C is at 16.3%. [7]
T-80 / Object 219 (1976): Initial model, with 1,000 hp gas turbine engine, coincidence rangefinder, and no missile capability. This model does not have fittings for explosive reactive armour . The turret is from the T-64A, and thus retains the use of the old coincidence rangefinder.
* Note: two versions: one contained a 16-cylinder 7HDL, co-developed by GE and the German firm Deutz-MWM, rated at 6000 HP; the other a 16-cylinder 7FDL rated at 4390 HP. The units equipped with the 7FDL were a sub-version AC6000 "Convertible" and were produced to get the type into operation while the 7HDL was developed.
The Baldwin VO-1000 is a diesel-electric switcher locomotive built by the Baldwin Locomotive Works between January 1939 and December 1946. These units were powered by a naturally aspirated eight- cylinder diesel engine rated at 1,000 horsepower (746 kW), and rode on a pair of two-axle trucks in a B-B wheel arrangement.
