Rental generating sets, also known as electric generators or simply generators, are devices that convert mechanical energy into electrical energy for use in external applications. Their operation is based on the principle of electromagnetic induction, which was discovered by Michael Faraday in the 1830s.
Generators are used in a wide range of contexts, from small portable applications, film and TV lighting services to large industrial installations. Below are some key aspects of generator sets:
Types of Generator Sets:
Portable: Lightweight and small, ideal for camping, operating tools in off-grid areas and for emergency back-up in homes.
Soundproof: They have a noise-reducing casing, making them suitable for locations where noise is a concern, such as events or residential areas.
Industrial: High-capacity generators designed to provide ample power for extended periods of time, such as in construction facilities or for use as backup systems in buildings or industrial processes.
Backup or Emergency: Permanently installed and automatically activated during power outages to keep essential businesses, hospitals, data servers and more up and running.
Fuels Used in Generator Sets:
Diesel: Very common, especially for high power applications because of their efficiency and durability.
Gasoline: Common in portable generators; however, they tend to be less efficient and have less durability than diesel.
Natural Gas: A cleaner option often used where a natural gas connection is available.
LPG (Liquefied Petroleum Gas): Used by portable and back-up generators for its cleanliness and convenience.
Biodiesel, Vegetable Oils and other alternative fuels: Used in some generators to reduce emissions and dependence on fossil fuels.
Main Components Generator Sets:
Engine: Produces the mechanical energy needed to generate electricity.
Alternator: Converts the mechanical energy of the engine into electrical energy.
Cooling and exhaust system: Maintains the engine at a suitable operating temperature and manages exhaust gases.
Lubrication system: Reduces wear on the engine's moving parts.
Starting battery: Provides the electricity needed to start the genset.
Control panel: Allows the user to start the generator, monitors its operation and, in some cases, connects it to the mains automatically in the event of a power cut.
Generator set applications:
Emergency back-up power: Hospitals, data centres, and homes.
Power supply for remote sites: Construction sites and campsites.
Outdoor events: Trade shows, concerts and weddings.
Industries: Manufacturing, agriculture and mining.
It is important to consider factors such as the amount of power required, the duration for which the generator will be required and the type of fuel when choosing a generator set. In addition, regular maintenance should be carried out to ensure that they operate efficiently and safely when needed.
