Diesel Generators
Known for their capability to manage large loads, diesel generators are the most common type of carrier gensets. CARB, or the California Air Resource Board, sets strict emission regulations for diesel carriers in California. These generators are highly valued for their fuel efficiency, durability, and power output. When managed properly, they can last over 30 years.
Natural Gas Generators
Natural gas carriers run on methane-based fuels, the most common being unreformed gas, which consists mainly of hydrogen and carbon. On the other hand, reformed gas is natural gas mixed with hydrogen. This type of generator is ideal for areas with a reliable natural gas supply. Although they generate less power than diesel gensets, the reduced emission profile suits them for a greener approach.
LPG Generators
Like natural gas generators, LPG carriers also have lower emissions than diesel. Liquefied petroleum gas generators emit up to 60% lower greenhouse gas emissions and 40% less nitrogen oxide than diesel gensets. LPG is cheaper in some areas but requires bulky storage tanks that could be difficult to install in some places.
Hybrid Generators
Hybrid generators are built to maximize fuel efficiency by switching between different power sources. They can operate on multiple fuels, including hydrogen, biogas, diesel, and more. Some are designed to work alongside photovoltaic technology to supplement power generation. Hybrid gensets are best for those who wish for a sustainable energy solution that can reduce dependence on a single fuel source.
Telecommunications
Telecommunication companies rely on gensets, especially when operating remote towers and data centres. For these places, a continuous and reliable power supply is a business-critical requirement. Carrier generators serve as backup power during outages or when the main grid is unavailable. They are used in maintaining network operations and ensuring uninterrupted communication services.
Construction
Like every other industry, construction companies require gensets to power tools, equipment, and temporary lighting. Many construction sites are located in areas where the main power supply isn't readily accessible. These settings employ carrier generators for efficient operation. They ensure work continues regardless of the status of the nearby electrical grid.
Healthcare
Hospitals and other healthcare facilities need to operate constantly. With critical medical equipment reliant on electrical power, any interruption can lead to dire consequences. Generator setsare used as a backup to power essential services like lighting, equipment, and emergency systems during power outages. They are also used in remote surgeries and other situations where the main power supply isn't available.
Agriculture
The agricultural industry depends on carrier generators for irrigation systems, lighting in greenhouses, and operation of other farming equipment. Many farms are located in remote areas with an unreliable power supply. Gensets are instrumental in ensuring production continues without interruptions due to power outages or lack of access to the electrical grid.
Mining
The mining industry operates in some of the most remote locations on the planet. Most of these places aren't connected to the electrical grid, so carrier generators become invaluable in powering equipment, lighting, and worker accommodation. They are used in the extraction process that requires a sustained heavy power supply.
Frequency
Typically, the frequency of a generator is calculated in hertz, and it depends on regions. For instance, 50 Hz is mostly used in Europe, Asia, Africa, and Australia, while 60 Hz is used in North America and parts of South America.
Engine Speed
The engine speed of a generator set is expressed in revolutions per minute (RPM). It is directly linked to the frequency. For a 50 Hz alternator, the engine speed is usually 1500 RPM. It is 1800 RPM for 60 Hz.
Voltage
This refers to the electrical potential difference measured between two points of a conducting medium. It can be rated in V or kV.
Prime Power
This is the maximum mean output of electrical power available for the use of the generator set. It is measured in kilowatts (KW) or kilovolt-amperes (KVA)
Standby Power
Standby poweris the maximum output achievable by a generator set and is offered for short periods during power outages. Like the prime power, it's also measured in KW or KVA.
Fuel Efficiency
This is especially true for diesel generators that can last for years when operated on fuel-efficient engines. Natural gas and propane generators are also designed to optimize fuel usage and, by extension, operational costs.
Automatic Start and Stop
Most modern carrier generators are built with automatic start and stop features. This enables the generator to automatically start when the power goes out and automatically stop when the power is back on.
Noise Reduction
Many new Carrier generators come with noise reduction features like soundproof enclosures. This ensures the operation doesn't interfere with the surrounding environment, especially in residential or urban areas. Noise can be a nuisance, particularly when it disrupts daily activities or sleep.
Portability
Some carrier generators are designed to be portable. These gensets are compact and can easily be transported from one location to another. They are ideal for temporary power needs or for use in multiple locations.
Smart Technology Integration
These generators are linked to mobile applications for monitoring and controlling their performance. Generators integrated with smart technology give the user real-time updates and alerts.
Installation
An automatic generator transfer switch(ATSTS) must be installed when the genset is connected to the main power supply. This switch seamlessly transfers power without damaging equipment. The generator must be placed on a level surface, protected from extreme weather, near fuel supply, and with proper ventilation. After installation, the system must be tested to ensure it operates correctly.
Maintenance
Carrier generator sets require regular oil changes, typically every 100-500 hours, depending on use. The fuel and air filters should be replaced every 200-400 hours. Battery terminals must be checked for corrosion every month, and batteries should be replaced after 3-5 years. Every 1-2 years or 2000 hours, coolant should be replaced and the cooling system inspected. Every 5 years or 3000 hours of usage, a major overhaul of the engine and generator components is needed.
Power Needs
The first consideration when selecting a carrier genset is determining how much power will be needed. Generators typically have multiple outlets that supply different wattages. It's important to know the wattage requirements of various appliances and equipment. This is done by calculating the power needs of essential devices and then choosing a generator that can handle the combined load without being overstrained.
Type
There are three main types of generators: standby, portable, and inverter. Standby generators are permanently installed and automatically provide backup power during outages. Portable generators can be easily moved and provide power in emergencies or for construction sites. Inverter generators supply a steady power level. This makes them ideal for sensitive electronics. The right type should depend on power needs and usage frequency.
Fuel Efficiency
Fuel efficiency is an important factor, especially given the rising fuel prices. An economical generator will be more cost-effective in the long run. Inverter generators are more fuel-efficient than conventional models. They adjust engine speed based on power requirements. Opting for a model with a large fuel tank also helps improve the runtime.
Noisiness
The noise level of a generator should also be considered, especially if it will be used at home or in a residential area. Noise levels are rated in decibels (dB). Standby and inverter generators are quieter than portable generators. They range from 40 to 70 dB.
Budget
Budget is another crucial factor when purchasing a carrier genset. Portable generators are more affordable and are ideal for temporary power needs. Standby generators offer the convenience of automatic power supply but are more expensive. Inverter generators are more advanced and provide clean and quiet power. These generators cost more to acquire.
A1. A carrier generator set is an electrical generating system that includes the generator and the prime mover coupled together to form a single piece of equipment.
A genset provides backup power during electrical outages. It is particularly useful in places where a continuous power supply is critical, such as in hospitals and data centres.
Domestic heating systems usually don't consume a lot of fuel. They only produce the electricity the home needs, which doesn't require extra fuel expenditure. The fuel cost is just as economical as utility rates.
Most standby generators can run continuously for up to 24 hours or longer if the fuel tank is properly maintained. In extreme circumstances, they can run for several days or weeks non-stop.
To extend the lifespan of a genset, it should be regularly serviced and maintained. It should also be protected from extreme weather elements and kept in a cool, dry, and well-ventilated environment.
