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]
The term "product change" includes changes to hardware, software, and firmware that occur over the entire life of a product. Product changes include those considered reportable and non-reportable. These changes may be applied by a supplier, a customer, or a contractor retained by the customer, depending on negotiated agreements.
Power was generated using a 6-cylinder Cummins HBI-600 diesel engine producing 150 hp (110 kW) at 1,800 rpm. [6] This engine powered a single GE GT-1503 main generator, which in turn provided electricity to the single rear-mounted GE-733 traction motor which powered the rear axle. Power was provided to the forward axle using a chain drive.
The base power may be the rating of a single piece of apparatus such as a motor or generator. If a system is being studied, the base power is usually chosen as a convenient round number such as 10 MVA or 100 MVA. The base voltage is chosen as the nominal rated voltage of the system. All other base quantities are derived from these two base ...
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]
The JMC class entered service in 1955 while the GE-built diesel locomotives entered service in 1956. On August 15, 1956, the MRR's steam locomotives ended their last regular services in Luzon. [17] Contemporary efforts towards electrification has started in the 1990s, with the North–South Commuter Railway being its latest incarnation.
In modern buildings, most emergency power systems have been and are still based on generators. Usually, these generators are diesel engine driven, although smaller buildings may use a gasoline-engine-driven generator. Some larger building have gas turbines, but they can take 5 or up to 30 minutes to produce power. [6]
A regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a regenerative process.. A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.
