Electric Power Generator UAE

P 275 Perkins Power Generator UAE

P 275 Perkins Power Generator UAE was first produced in 1831 and became very popular. The working of a generator is easy to understand as it transforms one type of energy into another one but the making of a generator is not a task anyone can do. it uses the energy supplied to it to push the electric charges through an electrical circuit. This flow of many electrical charges is the reason electricity is produced and is available for use. There are few things necessary in making or working of an electrical generator. First and the most important thing is the engine. The engine is the place where the energy of any type enters. The bigger the engine is the more energy it can take in and the more the electrical power it can produce.
Maintenance of the engine and its cleanliness is very important for an engine to work properly. Also, the type of fuel used is also very important as a good type of fuel can produce more electrical power.

Secondly, the Alternator is the part of a generator where electrical power is received as an output from the energy that was inputted in the first place. Next up is the fuel holder. This is the tank where the fuel that is to be used is placed. Its capacity determines the amount of time a generator can work without stoppage. In small generators, the fuel holder is placed with the rest of the components. Control panel controls the voltage of electrical output of the generator, So Electric generator price in UAE wary from quality, size and power.

Oil may be the world’s favorite fuel, but not for much longer. Modern homes are powered mostly by electricity and it won’t be long before most of us are driving electric cars as well. Electricity is superbly convenient. You can produce it in all kinds of different ways using everything from coal and oil to wind and waves. You can make it in one place and use it on the other side of the world if you want to. And, once you’ve produced it, you can store it in batteries and use it days, weeks, months, or even years later. What makes electric power possible—and indeed practical—is a superb electromagnetic device called an electricity generator: a kind of electric motor working in reverse that converts ordinary energy into electricity. Let’s take a closer look at generators and find out how they work!

Where does electricity come from?

The best way to understand electricity is to start by giving it its proper name: electrical energy. If you want to run anything electrical, from a toaster or a toothbrush to an MP3 player or a television, you need to feed it a steady supply of electrical energy. Where are you going to get that from? There’s a basic law of physics called the conservation of energy that explains how you can get energy—and how you can’t. According to this law, there’s a fixed amount of energy in the universe and some good news and some bad news about what we can do with it. The bad news is that we can’t create more energy than we have already; the good news is that we can’t destroy any energy either. All we can ever do with energy is convert it from one form into another.

How can we generate electricity?

If you’ve read our detailed article about electric motors, you’ll already know pretty much how generators work: a generator is just an electric motor working in reverse. If you’ve not read that article, you might like to take a quick look before reading on— but here’s a quick summary either way.

An electric motor is essentially just a tight coil of copper wire wrapped around an iron core that’s free to rotate at high speed inside a powerful, permanent magnet. When you feed electricity into the copper coil, it becomes a temporary, electrically powered magnet—in other words, an electromagnet—and generates a magnetic field all around it. This temporary magnetic field pushes against the magnetic field that the permanent magnet creates and forces the coil to rotate. By a bit of clever design, the coil can be made to rotate continuously in the same direction, spinning round and round and powering anything from an electric toothbrush to an electric train.

So how is a generator different? Suppose you have an electric toothbrush with a rechargeable battery inside. Instead of letting the battery power the motor that pushes the brush, what if you did the opposite? What if you turned the brush back and forth repeatedly? What you’d be doing would be manually turning the electric motor’s axle around. That would make the copper coil inside the motor turn around repeatedly inside its permanent magnet. If you move an electric wire inside a magnetic field, you make electricity flow through the wire—in effect, you generate electricity. So keep turning the toothbrush long enough and, in theory, you would generate enough electricity to recharge its battery. That, in effect, is how a generator works. (Actually, it’s a little bit more tricky than this and you can’t actually recharge your toothbrush this way, though you’re welcome to try!)

How Does an Electric Power Generator UAE Work?

Generators are basically coils of electric conductors, normally copper wire, that are tightly wound onto a metal core and are mounted to turn around inside an exhibit of large magnets. An electric conductor moves through a magnetic field, the magnetism will interface with the electrons in the conductor to induce a flow of electrical current inside it.

The conductor coil and its core are called the armature, connecting the armature to the shaft of a mechanical power source, for example an motor, the copper conductor can turn at exceptionally increased speed over the magnetic field.

The point when the generator armature first starts to turn, then there is a weak magnetic field in the iron pole shoes. As the armature turns, it starts to raise voltage. Some of this voltage is making on the field windings through the generator regulator. This impressed voltage builds up stronger winding current, raises the strength of the magnetic field. The expanded field produces more voltage in the armature. This, in turn, make more current in the field windings, with a resultant higher armature voltage. At this time the signs of the shoes depended on the direction of flow of current in the field winding. The opposite signs will give current to flow in wrong direction.

Types of Electric Power Generator in UAE:

The generators are classified into types.

1. AC generators
2. DC generators
   

   AC Generators:

   These are also called as alternators. It is the most important means of producing electrical power in many of the places since now days all the consumers are using AC. It works based on principle of the electromagnetic induction. These are of two types one is induction generator and other one is synchronous generator. The induction generator requires no separate DC excitation, regulator controls, frequency control or governor. This concept takes place when conductor coils turn in a magnetic field actuating a current and a voltage. The generators should run at a consistent speed to convey a stable AC voltage, even no load is accessible.

Synchronous generators are large size generators mainly used in power plants. These may be rotating field type or rotating armature type. In rotating armature type, armature is at rotor and field is at stator. Rotor armature current is taken through slip rings and brushes. These are limited due to high wind losses. These are used for low power output applications. Rotating field type of alternator is widely used because of high power generation capability and absence of slip rings and brushes.

It can be either 3 phase or two phase generators. A two-phase alternator produces two completely separate voltages. Each voltage may be considered as a single-phase voltage. Each is generated voltage completely independent of the other. The three-phase alternator has three single-phase windings spaced such that the voltage induced in any one phase is displaced by 120º from the other two. These can be connected either delta or wye connections. In Delta Connection each coil end is connected together to form a closed loop. A Delta Connection appears like the Greek Letter Delta (Δ). In Wye Connection one end of each coil connected together and the other end of each coil left open for external connections. A Wye Connection appears as the letter Y.

Advantages of AC Generator:

Perkins OEM Generators are generally maintenance free, because of absence of brushes.
Easily step up and step down through transformers.
Transmission link size might be thinner because of step up feature
Size of the generator relatively smaller than DC machine
Losses are relatively less than DC machine
These Generator breakers are relatively smaller than DC breakers

 

DC Generators:

DC generator is typically found in off-grid applications. These generators give a seamless power supply directly into electric storage devices and DC power grids without novel equipment. The stored power is carries to loads through dc-ac converters. The DC generators could be controlled back to an unmoving speed as batteries tend to be stimulating to recover considerably more fuel.

Classification of DC Generators

D.C Generators are classified according to the way their magnetic field is developed in the stator of the machine.

permanent-magnet DC generators
Separately-excite DC generators and
Self-excited DC generators.
Permanent magnet DC generators do not require external field excitation because it has permanent magnets to produce the flux. These are used for low power applications like dynamos. Separately-excite DC generators requires external field excitation to produce the magnetic flux. We can also vary the excitation to get variable output power. These are used in electro plating and electro refining applications. Due to residual magnetism present in the poles of the stator self-excited DC generators can able to produce their own magnetic field ones it is started. These are simple in design and no need to have the external circuit to vary the field excitation. Again these self-excited DC generators are classified into shunt, series, and compound generators.

These are used in applications like battery charging, welding, ordinary lightening applications etc.

Advantages of DC Generator:

Mainly DC machines have the wide variety of operating characteristics which can be obtained by selection of the method of excitation of the field windings.
The output voltage can be smoothed by regularly arranging the coils around the armature .This leads to less fluctuations which is desirable for some steady state applications.
No shielding need for radiation so cable cost will be less as compared to AC.

Main Components Of Electric Power Generator UAE

You must be thinking that diesel generator is efficient and swift. What makes it do that? What is the basic construction of this product and what elements have been housed in it for perfect results? Well, to your amaze, it comes with various components that team up to provide the efficiency. It is not a one element army but they have to combine up to give the results. The reason behind this logic is that it works on the principle of conversion, which means that specific energy needs to be collected, converted and dissipated. You will find a number of elements in the construction of this diesel generator and the list of these elements is as follows:

Starter Motor

A permanent magnet or a series parallel starter motor has been housed in the construction of this diesel generator. It has been wound direct current electric motor with a starter solenoid which has been mounted on it. It functions as soon as the current is applied to the solenoid with the help of a starting battery. It has been operated using a key operated switch. A lever is engaged by the solenoid that pushes itself out of the drive pinion housed on the driveshaft to perform the required function.

Flywheel

Flywheel is a rotating or a spinning machine which stores rotational energy. The rotation in turn causes mechanical energy and it already has been blessed with enough amount of inertia. This has been done to provide a balance and to resist the changes in the rotational speed. Balance makes the whole game. A flywheel is present for three main reasons. It provides continuous energy when the energy source is not continuous.
It also delivers energy beyond the ability of the energy source. It also collects energy in the flywheel overtime and releases it quickly. Apart from these functions, a flywheel is present to control the total orientation of the system. Angular momentum is very necessary when you are experiencing subjects like torque, inertia and rotation. This momentum is thereof provided by the flywheel to continue the effective and continuous operations throughout the cycle.

Alternator

You might have come around this term often. It is basically an electromechanical device whose main purpose is conversion. It converts mechanical energy into electrical energy and is the core element housed in the construction of the diesel generator. It uses alternating current to carry on with its processes. It is shaped just like a disc and is expected to be flexible in structure. This is done so that it has the ability to cope up with the changes under high torque loads.

Control Panel

To maintain and monitor the features of this diesel generator, a control panel is present. It is the brain of the entire system and controls all the aspects of it. Upon its signal, the motor gets started.

Circuit Breaker

Overloading or short circuiting is a fear and it can attack the system of the generator anytime. To save it from any type of accident, a circuit breaker is present. It is an automatically operated switch and works on its own. It acts as a protective sheet to the system and protects it from any kind of damage or discrepancy. As soon as it detects a fault in the system, it interrupts the continuous flow of electricity and hence shuts down the operations of the generator.

Circuit breakers are made in various sizes to suit the generator’s needs. They can fit in with any electrical appliance and perform the same function. You will see these attached to most of the appliances in your house.

Battery

Diesel generator UAE cannot function without a battery. It is considered to be its main component and its function is to supply electric energy to the power source. The starter motor and the control panel of the generator work on its presence. Without a battery, nothing is functional – not even your control panel.

Cooling System

A diesel generator UAE is surrounded by multiple and heavy functions. It’s all about the conversion and dissipation of different forms of energies. Chances are that the system might heat up and ignite which can be hazardous. To save the irregularity of the system, a cooling mechanism is present in the structure of the diesel generator. Engine coolant is a liquid present in the cooling system and its function is to cool down all the internal combustion. It runs through the engine block and is mostly water based. In rare cases, you might find it composed of oil as well.
To force it to circulate, a water pump is employed in the system and to force the air through the radiator an axial fan is present.
Hot air is blown out of the engine using the fan and towards the chamber where the coolant gets adequate time to cool itself.

Fan

A fan is termed as the rotating arrangement of air blades and is housed in a case. Its main purpose is to cool down the entire system and to process on the operations with ultimate perfection. It is mostly protected and performs the cooling operations of the system with ultimate grace.

Coolant Tank

Reactions always invite overheating. When chemical reactions are taking place, the system of the product can overheat. To prevent the overheating, coolant is present. It is a fluid which is present to prevent overheating in the system. It transfers the heat produced by the main device to other carrier devices. This way the heat is transferred slowly and gradually and the system is prevented from overheating.
An ideal coolant has many different specifications. It has high thermal capacity, low viscosity, cheap and is not toxic. To avoid any sort of chemical reactions, it is chemically inert. It does not promote the corrosion of the cooling system and makes it safe and durable to use.

Deciding the size of generator you need to use:

The most important decision you need to make while buying a generator, is to determine the right size of generator that can manage all the power generation needed for your machinery. Normally generators are used as the stand in power supply or the primary power supply. But if the power supplied by your generator is less than required then it has no use and can even damage your equipment raising the cost even higher. One thing to keep in mind while buying a generator is that whether the power generated and the power required are up to your estimate or not. This blind guess can be made quite accurate to some extent by considering some factors along with the amount of power required by machinery.

Following are the general types of generators and deciding between them can leave someone startled sometimes:

• Single Phase Power Generator
• Three Phase Power Generator
• kW
• KVA
• Welder
• Standby
• Motor Starting

To relieve the customers from this mess of calculating each and every factor, we have explained all the main factors that are useful while buying the right generator for you. Note that all the information and suggestions concerning the purchase of required generator are not made by a certified engineer, electrician or a generator salesman. So it is advised to always have a word with a professional while buying the generator before striking the final deal. However, our guide will certainly give you a general idea of what to expect from the market.

Generators by Various Sizes:

With all the progress in science and technology, the generator industry has changed vividly. These days you can buy a generator that is portable or a full power house for a whole building. The home generators normally have an electrical capacity from 5 kilo Watt to 50 kilo Watt. However, to run all the machinery in the industries, industrial generators have an electrical capacity of 50 kilo Watt to 3 Mega Watt. The compact generators are applicable in following places:

• Houses
• RV’s
• Mid Size Offices

The large industrial grade generators are used in the more practical energy consumption scenarios like:

• Large Business Entities
• Data Centers
• Buildings
• Production Plants
• Industrial Buildings

Generator Sizing by Power:

People normally buy small capacity generators to be used as a standby power source. The reason is that it is not required to run all the time. This logic can be quite dangerous for you as generator sizing according to power required is the most wronged decision that people make. People randomly purchase a generator without estimating the work load that it has to handle. The worst case is that it can totally destroy your new generator. The other major risk is that it can also damage the equipment it is required to power or limit the efficiency of productivity of the equipment that depends on it. A wise saying is that “more is always better than less”, which also fails perfectly while buying the right generator.

Deciding the right engine for generator:

It is advised to always consult with a professional certified electrician while buying the right sized engine or generator. It can save you from damage and also benefit financially. To show the right direction for purchasing the right product, we have the following guide for you:

Know your Requirements:

People usually go to market and buy the cheapest product without considering any factors but to save cash. This is the wrong choice and can be very costly in the long run. It is advised to make a list of requirements to have in your product so it may benefit in the long run. Following is the guide on setting your requirements:

• List all the items meant to be powered by the generator
• List all the operating voltages of all the items powered by the generator
• Calculate the power in both kVA and kW

Calculating the starting and running power requirements:

It is advised to list all the starting and running power requirements for all the equipment that is meant to be powered. You need to do calculations early on to avoid the damage. All the required information about starting and running wattage of equipment can be found at the following resources:

• Identification plates of the equipment
• Owner’s Manual provided with the Equipment
• Online webpage of the equipment on Manufacturer’s Website

Conversion of Ampere into Watt:

Usually the amount of electricity needed by the equipment is given in the form of Amperes at the above mentioned sources. The conversion of Ampere consumption of the item into Wattage is simple and can be performed according to the following steps:

• For Resistive Load:

Wattage = Amperes x Volts

• For Reactive Load:

Wattage = Load Factor x (Amperes x Volts)

Estimation of Power Requirement:

There are a number of cases when the consumer can’t find the owner’s manual to know the consumption rate of the equipment. For your ease, we have provided a Sample Power Consumption Chart. This chart can help you estimate the wattage rate for some common tools and appliances usually used in the houses and offices. This chart is provided just as an example to let you guess the estimated differences between starting and running wattage and how every device consumes different amount of energy. The sources for consultation are listed as following:

• The manufacturer of the Equipment
• Certified Electrician

Factors for Calculation:

The power determination of any generator is normally based on the following factors:

• Type of generator
• Number of appliances powered by the generator
• Schedule for utilizing or running the generator

Parameters for Power Calculation:
