Hydrogen is sometimes used as a coolant for the stator windings of large generator units since it is more efficient at absorbing heat than other coolants. Hydrogen removes heat from the generator and transfers it through a heat exchanger into a secondary cooling circuit that contains de-mineralized water as a coolant.

This is why very large generators and small power plants often have large cooling towers next to them. For all other common applications, both residential and industrial, a standard radiator and fan is mounted on the generator and works as the primary cooling system. It is essential to check the coolant levels of the generator on a daily basis. The cooling system and raw water pump should be flushed after every hours and the heat exchanger should be cleaned after every 2, hours of generator operation.

The generator should be placed in an open and ventilated area that has adequate supply of fresh air. The National Electric Code NEC mandates that a minimum space of 3 feet should be allowed on all sides of the generator to ensure free flow of cooling air. Hence, it is essential to install an adequate exhaust system to dispose of the exhaust gases. Exhaust pipes are usually made of cast iron, wrought iron, or steel.

These need to be freestanding and should not be supported by the engine of the generator. The exhaust pipe terminates outdoors and leads away from doors, windows and other openings to the house or building. You must ensure that the exhaust system of your generator is not connected to that of any other equipment.

You should also consult the local city ordinances to determine whether your generator operation will need to obtain an approval from the local authorities to ensure you are conforming to local laws a protect against fines and other penalties.

Lubricating System Since the generator comprises moving parts in its engine, it requires lubrication to ensure durability and smooth operations for a long period of time. You should check the level of lubricating oil every 8 hours of generator operation. You should also check for any leakages of lubricant and change the lubricating oil every hours of generator operation. Battery Charger The st e art function of a generator is battery-operated.

If the float voltage is very low, the battery will remain undercharged. If the float voltage is very high, it will shorten the life of the battery. Battery chargers are usually made of stainless steel to prevent corrosion. In general, emergency generators and generators that run for less than hours per year are not subject to federal generator emissions requirements, however, permanently installed prime generators and standby generators are subject to federal emissions requirements under three EPA rules:.

The good news is that many newer gensets already meet generator emissions standards thanks to manufacturing improvements. Older gensets may be grandfathered in, making them exempt from federal regulations, and subject only to state and local emissions standards.

Emissions control requirements vary by manufacturer, generator size, and production date so the best way to determine your emissions requirements is to talk to your generator dealer or manufacturer.

One of the most important components of modern-day generators is the generator control panel. When the power level drops or cuts out entirely, the ATS signals the control panel to start up the generator. Likewise, when incoming power is restored, the ATS signals the control panel to shut the generator down and reconnects to power grid.

Generators are engines and require routine engine maintenance to ensure proper operation. Since many generators are relied on to provide back-up power in the event of emergencies, it is crucial for operators to conduct regular checks and inspections of their gensets to ensure the machine will operate as needed, when needed.

The best generator maintenance routine is the one recommended by the manufacturer, but, at a minimum, all generator maintenance plans should include regular and routine:. Be sure to maintain a maintenance log for recordkeeping. Include all readings, fluid levels, etc. These records can be compared against future records and used to help detect abnormalities or changes in operation which may clue you in to hidden issues that could become major problems if left unchecked.

Generators can last for decades when properly maintained. These simple, small investments will definitely pay off over time by saving on expensive repairs or even full genset replacement. The single most important part of installing a backup generator or a prime generator is getting the size right. Even worse, running an undersized machine can strain the unit, causing the generator to cut out mid-operation, may lead to premature generator failure, and can possibly damaging the devices connected to it.

In other words, you still require the generator to provide a certain amount of power whether the generator is run continuously or only on an emergency basis. Installing a generator that provides much more power than you need is a waste of resources.

Generators range in power capacity from 5 kW to 50 kW in the residential market and from 50 kW to over 3 Megawatts in the commercial and industrial markets, giving buyers plenty of choices, but also raising plenty of questions as to which generator is right for them. Correctly sizing a generator involves several factors and considerations. The best way to ensure you have sized the generator correctly is to consult a certified electrician. An electrician can determine your exact power needs, your electrical system capacity and any necessary upgrades, and how to best install a generator.

Once you have the total power requirements of facility, you can buy a generator that best meets your needs. Used and surplus generators are a great way to save money and still get a quality machine.

Since generators are so durable and long-lasting, even well-maintained used generators have a lot of life left in them. Reputable generator suppliers will have checked the unit over for issues and reviewed the maintenance log and possibly even have made necessary repairs before they put the generator up for sale. As long as you have a maintenance record and know the history of the generator, there is no reason to shy away from used generators.

Surplus generators offer similar benefits but without any or with very few running hours on the machine. There are many generator suppliers in the U. If you plan to buy a generator as a business asset and a way to keep your doors open during an emergency, take your time and work with a dealer, broker, or supplier that has many years of experience.

Find a seller who can answer your questions, assess your situation, and guide you to the best purchasing decision based on your specific needs. We sell used generators and surplus generators that have undergone a rigorous inspection and testing to small businesses and Fortune companies alike all across the U.

The engine is used to rotate the axle of an electrical conductor in a magnetic field which creates electricity. Alternator or genhead - creates the electrical output from the engine generated mechanical energy. The mechanical energy is used to rotate a copper coil wrapped around an iron core inside powerful a permanent magnet or electric magnet.
