In 1998, Generac sold its portable products division to the Beacon group, a private equity firm, who later sold it to Briggs & Stratton Corporation. Upon expiration of a non-compete agreement related to the sale in 2007, Generac re-entered the portable generator market in 2008. [7] In late 2006, Generac was purchased by CCMP Capital of New York ...
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. The same model generator will carry a higher rating for standby service than it will for continuous duty. Manufacturers give each set a rating based on internationally agreed definitions.
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 ...
Standby generators. A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]
Connecting a generator with the wrong phase sequence will result in large, possibly damaging, currents as the system voltages are opposite to those of the generator terminal voltages. [ 2 ] The voltage, frequency and phase angle must be controlled each time a generator is to be connected to a grid.
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
Since the rotational speed and thus the kinetic energy of a synchronous generator does not depend on its current power level, the inertia of the overall grid is related to the inertia constants of the running generators; [7] at the time of lower power demand (say, at night) there might be less generators running, and thus a similar contingency ...
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.
