The CIS is not an expensive feature but it plays an important role in engine durability especially if you need to use your generator often or for long durations. It contains an assembly of stationary and moving parts encased in a housing. The components work together to cause relative movement between the magnetic and electric fields, which in turn generates electricity.
It contains a set of electrical conductors wound in coils over an iron core. The rotor generates a moving magnetic field around the stator, which induces a voltage difference between the windings of the stator. This produces the alternating current AC output of the generator. The following are the factors that you need to keep in mind while assessing the alternator of a generator:.
Plastic housings get deformed with time and cause the moving parts of the alternator to be exposed. This increases wear and tear and more importantly, is hazardous to the user. The fuel tank usually has sufficient capacity to keep the generator operational for 6 to 8 hours on an average. For commercial applications, it may be necessary to erect and install an external fuel tank. All such installations are subject to the approval of the City Planning Division.
Click the following link for further details regarding fuel tanks for generators. Common features of the fuel system include the following: a Pipe connection from fuel tank to engine — The supply line directs fuel from the tank to the engine and the return line directs fuel from the engine to the tank.
When you refill the fuel tank, ensure metal-to-metal contact between the filler nozzle and the fuel tank to avoid sparks. The fuel pump is typically electrically operated. Voltage Regulator As the name implies, this component regulates the output voltage of the generator.
The mechanism is described below against each component that plays a part in the cyclical process of voltage regulation. The voltage regulator then feeds this DC current to a set of secondary windings in the stator, known as exciter windings.
The exciter windings are connected to units known as rotating rectifiers. This cycle continues till the generator begins to produce output voltage equivalent to its full operating capacity. In general, most commercial generators can be converted from 60 Hz to 50 Hz. The general rule of thumb is 60 Hz machines run at Rpm and 50 Hz generators run at Rpm. In some cases, parts may have to be replaced or further modifications made.
Larger machines or machines already set at low Rpm are different and should always be evaluated on a case by case basis. We prefer to have our experienced technicians look at each generator in detail in order to determine the feasibility and what all will be required.
How do I determine what size Generator I need? Getting a generator that can handle all your power generation needs is one of the most critical aspects of the purchasing decision. Whether you are interested in prime or standby power, if your new generator can't meet your specific requirements then it simply won't be doing anyone any good because it can put undue stress on the unit and even damage some of the devices connected to it.
Determining exactly what size of generator to get is often very difficult and involves a number of factors and considerations. To get more detailed information on this subject, please visit our expanded article on Sizing a Generator. Articles and Info Why Use Diesel? New vs. Search for:. With 12, starting watts, this dual fuel generator can run on propane or electric and has an electric start and low-oil shut off.
This Champion is quieter and lighter than equally powerful generators and can be plugged into RV or home outlets or run on gas for up to 17 hours. This compact generator with a one-gallon tank and variety of outlets is safe to use to charge electronics. With its remote key fob and easy push-button start, you can safely run this generator up to feet away from your home on gas or propane.
Installing a 3-pole transfer switch should solve the problem. If it doesn't, you have to hunt down the ground fault lurking somewhere in the electrical system.
For example, you may have calculated the power draw of your well pump. If it turns out that the pump motor requires more power than you thought, stage your power consumption so that nothing else is drawing power or only minor power and allow the well pump to have complete access to the generator's full output when it charges the well tank.
The last thing you want is an under-voltage to big loads like the well pump, which will eventually damage it. Electric motors can surge up to three times their rated current during their first few seconds of startup. Inexpensive generators from companies you've never heard of may be lacking in the quality of their electrical output.
For example, the generator produces volts, but not consistently. That bad news gets even worse when the generator is undersized. Now its low power quality under normal operating conditions gets even worse as increased demand is placed on it. Both inexpensive consumer electronics that huge flat screen TV that was suspiciously inexpensive at a major retailer and major appliances often have poor power-filtering capability in their DC circuitry.
They both may be vulnerable to the poor power quality produced by generators manufactured by fly-by-night companies. The result will be damage to your appliances or electronics. Our advice is to stick with well-known generator brands, particularly those by manufacturers that belong to the Portable Generator Manufacturers Association.
That's not a guarantee against power-quality problems, but it certainly improves the odds. Type keyword s to search. Today's Top Stories. TrongNguyen Getty Images. So do we. The transfer switch has three purposes: It isolates the circuits in the house that you want to power; all other circuits are left without access to power, helping to prevent overloading.
But late in a tight ballgame he needs to come in and throw heat for just one inning. You need the confidence that a reliable generator is going to provide immediate and sustained, backup power. If your generator does not seem to be operating normally, it is vitally important to know why. To us, any question you might have about it is a good question. In compact 2 to 3 minute videos we have compiled the collective knowledge we have gained over thirty years of fixing generators.
We have produced over a dozen videos covering three major areas of concern:. The Generator Genius videos would provide a comprehensive tutorial for that manager. We might learn something ourselves.
