Power generators have two main components. An engine that burns fuel and supplies electricity, and a generator head that converts it into electricity. The motor and the generator head together form a standard generator. Generators are available in two basic versions: backup generators and portable generators like
Portable generators supply electricity for a short time in remote areas, such as construction sites. In an emergency, they can also use vital equipment in the event of a power failure. Portable generators tend to be smaller and cheaper than backup generators. They have built-in fuel tanks that allow them to travel anywhere, and standard sockets that can be connected to standard expansion cables. Portable generators should never be operated indoors, as these fumes can cause serious health problems such as death if used indoors.
Standby generators offer power from 7 kW to several hundred kW. They help offset the harmful effects of power outages. Backup generators, which are permanently installed as an emergency power source for your home, cottage or business, are firmly connected to your home or electrical system in your building and normally receive fuel from built-in large tanks. fuel that can run longer. Safety features can prevent injuries and damage to your generator.
Good backup generators fail when they lose oil pressure, overheat or work too hard. Standby generators also have mild steel or aluminum covers, a good silencer to reduce noise and meet all applicable emission regulations. Standby generators need to be run once a week and run for 15 minutes to “work out” – make sure they are ready when needed.
Diesel is a popular fuel choice for larger commercial generators. Diesel generators are probably more reliable and relatively cheaper to operate than natural gas generators such as propane, diesel is now very clean and non-smoking. Diesel is also safer for storage than gasoline and lasts longer. Natural gas and propane generator:
Standby generators can run on natural gas such as propane. The backup generator connects to the utility networks and pumps fuel as needed. Choose between natural gas and propane generators according to what is available in your area. Unlike diesel generators, additional maintenance is required. Natural gas and propane generators can be sensitive to pressure and fuel volume, so high quality compounds are essential. Gasoline generators:
Cheaper portable generators usually run on gasoline and are considered gasoline-powered generators. Fuel cannot be stored for a long time, so consider a portable diesel generator if you want to have a portable generator nearby in case of an emergency.
Generators require air cooling or have a liquid cooling system to prevent overheating. Like any engine, one engine generates less heat, with faster generators generating more heat than slower generators. Generators made for the North American market operate at one of two speeds: 1800 RPM or 3600 RPM. 1800 rpm engines tend to last longer and quieter; 3600 rpm engines are smaller and lighter.
Air-cooled generators are shorter than liquid-cooled generators, but they produce a lot of noise and are less efficient. Portable generators are almost always air-cooled models with 3600 rpm.
Standby generators 12 kW and larger typically run at 1800 rpm and use quiet, reliable and efficient liquid-cooled systems. Liquid-cooled generators are usually more expensive to purchase and maintain, but they last longer and can run all the time. Determine what size generator you need:
The power produced by the generator is measured in voltage and watts. When choosing a generator, first determine your specific voltage requirements and then you can choose a generator model that provides enough power for everything you want it to run.
Voltage is a measure of the “pressure” of an electric current. In the US, the typical household voltage is single-phase, 120 volts. Most households have a 120/240V service, which means they have two 120V circuits that combine to supply 240V for appliances that are hungry, such as electrical fittings, central air conditioning and water pumps. Many small businesses use this 120/240 V service and can benefit from 120/240 V generators.
Large companies usually have different power needs and use three-phase power, which drives high-performance motors better than standard single-phase household operation. In the US, a three-phase power supply usually produces 120/208 volts or 277/480 volts and you can find 120/208 V generators and 277/480 V generators operating at these common voltages. Find out what voltage your company is currently using so that you can find the generator you are connecting to.
Watt measures the “volume” of electricity produced by a generator. Add watt requirements to any additional equipment or parts of equipment you need to power the generator. The smallest generators can produce about 800 watts, while the largest industrial generators can produce 500,000 watts (500 kilowatts or kW) or more. Small businesses usually need generators that can produce 15 kW to 100 kW.
Before choosing a generator, especially backup generators, you need to decide what equipment you want to use with it. The “direct” large electric generator provides just enough power to power all your necessary equipment. Common equipment includes refrigerators, freezers, security and access systems, sludge pumps, headlights, electric gates as well as overhead doors, ejector pumps, well pumps and septic tanks. Keep in mind that any electronic device you add to the list will add the performance you need. While a light bulb can only add 70 watts, a medium-sized central air conditioner can draw 4,000 watts or more.
Limit the choice of appliances that are very important in the event of a power failure, and reduce your overall costs. It is very low watts and you can overwork the electric generator, which can damage it and everything in which it is involved. Too many watts and you spend money on the first purchase of a generator and fuel. Precise determination of the watts that your equipment will require will help you get a generator that can meet your energy needs without spending too much.
Instead of estimating, always check the power requirements of the equipment that must be supported by your generator. While as a reseller you can get good advice on what size generator your business or household needs, you should always meet the power requirements of your equipment before making a purchase decision. A lot is always better. Call an electrician to measure power: A qualified electrician can use an ammeter (a device that measures electricity) to determine how much each piece of equipment needs. The total power consumption measured by an electrician for each device to obtain your basic energy consumption.
By researching, you can find out how much your device can get on its own. Most devices state their electrical requirements in their operating instructions and also on their nameplates. The number you want to get is watts, and as you remember from high school physics, watts = volts x amps. Many devices list amplifiers at a given voltage, so simply multiply them to see what power they can get.
Electric motors consume more starting power than they run, which means that electronic devices have important control components – such as fans, pumps, refrigerator compressors and refrigerator winds – they can use up to three times more electricity to start. don’t stop running. Keep one factor in these startup requirements when determining how much power you need from the generator. Fortunately, many devices rarely start at the same time, so you need to add enough power to the power requirements for the devices with the highest startup requirements.
Think about which device has the biggest difference between the operating load and the initial load. Then add this number to the total operating load of the device to determine your total power requirement. Plan to purchase a generator marked for a capacity that is almost 20% higher than your requirements. The additional capacity will help you avoid overloading the generator, give you room to add a few small devices, and help extend the life of the generator.
Be sure to compare the marked capacity of different models, not the maximum capacity. The electric generator can deliver its maximum power in a maximum of 30 minutes before it starts to overheat. Rated capacity is the level of power that can be continuously supplied by the generator, usually over 90% of maximum power.
Before you buy, you know exactly what you need to include in the generator installation. Then choose a qualified electrician if you have it directly connected to your home.
Backup generators connected to your company’s electrical system require proper installation to prevent generator failure or overheating and damage to your existing wiring and equipment. Backup generators can be sensitive to pressure and fuel volume, so a high quality connection is essential. Show location:
If you are planning to create a permanent hook in your house or build the location of your existing electrical service panel, it is important. The generator will be located outside but close to your building, as a central air conditioner, and for easy installation it is best if it is placed close to the electrical panel.
