About Us

Vaigunths business started in 1997 in India as Vaigunth Ener Tek (P) Ltd.The business

was originally based on a unique, Twisted and Aero Dynamic wind turbine System, Solar

Thermal Electric Systems and these are all developed by Vaigunth Ener Tek (P) Ltd and

registered in India. As the business developed, the company realized that what a customer

really needed is not just the products, no matter how efficient and ingenious it is, but a

complete power system that is based on sound engineering and economics.

Vaigunth headquartered in Chennai and the office at Kanyakumari is responsible for

manufacturing, research and development, field engineering, after sales service and technical

training. By adopting quality manufacturing methodologies, the company is able to meet the

ever increasing and changing demands from the market place. Since 1998, Vaigunth installed

many stand-alone remote area power systems in different parts of the world.

Small Wind Turbines

One of the main benefits of wind energy is economic gain, both for individuals and for

communities. Individuals can save money on their energy bills, and even make money, by

generating wind power. Communities can diversify their economies and enjoy greater reliance

on local resources when their members invest in wind.

Vaigunth specializes in providing the most economical power solution be it, using free

energy from wind, passive solar, solar panels, or any combination theyre of. We have

personally tested all of our components to ensure our systems are assembled with the most

compatible, quality, robust, commercially available components on the market, our wind

turbines are designed for low rated velocity (Less than 9.5 m/s).

In a response to a world need we have developed our own designed wind

turbine,which is designed to produces a usable amount of power at its annual average wind

speed of 4 m/s. A World Bank study stated that on 80% of the world land mass there is an

average wind speed of 4 m/s. This product was developed as one option in helping to bring

dependable electricity to remote locations all over the developing world.

WIND TURBINE DESIGN

Rotor

The portion of the wind turbine that collects energy from the wind is called the rotor.The rotor usually consists of two or more wooden, fiberglass or metal blades, which rotateabout an axis (horizontal or vertical) at a rate determined by the wind speed and the shape ofthe blades. The blades are attached to the hub, which in turn is attached to the main shaft.

Drag Design

Blade designs operate on either the principle of drag or lift. For the drag design, thewind literally pushes the blades out of the way. Drag powered wind turbines are characterizedby slower rotational speeds and high torque capabilities. They are useful for the pumping,sawing or grinding work that Dutch, farm and similar "work-horse" windmills perform. Forexample, a farm-type windmill must develop high torque at start-up in order to pump, or lift,water from a deep well.

Lift Design

The lift blade design employs the same principle that enables airplanes, kites and birdsto fly. The blade is essentially an airfoil, or wing. When airflows past the blade, a wind speedand pressure differential is created between the upper and lower blade surfaces. The pressureat the lower surface is greater and thus acts to "lift" the blade. When blades are attached to acentral axis, like a wind turbine rotor, the lift is translated into rotational motion. Lift-poweredwind turbines have much higher rotational speeds than drag types and therefore well suitedfor electricity generation.

Tip Speed Ratio

The tip-speed is the ratio of the rotational speed of the blade to the wind speed, thelarger this ratio, the faster the rotation of the wind turbine rotor at a given wind speed.Electricity generation requires high rotational speeds. Lift-type wind turbines have maximumtip-speed ratios of around 10, while drag-type ratios are approximately 1. Given the highrotational speed requirements of electrical generators, it is clear that the lift-type wind turbineis most practical for this application.

The number of blades that make up a rotor and the total area they cover affect windturbine performance. For a lift-type rotor to function effectively, the wind must flow smoothlyover the blades. To avoid turbulence, spacing between blades should be great enough so that

one blade will not encounter the disturbed, weaker air flow causedby the blade which passedbefore it. It is because of this requirement that most wind turbines have only two or three

blades on their rotors.

Ener Tek Rotor Design

Page 4 of 22


5/22

Chennai

The rotor system consists of three fiberglass blades. The blades convert the energy of thewind into rotational forces that can drive the generator through shaft. The airfoil on the EnerTek Turbine is the modified NACA 23015 developed for the Ener Tek Turbine by VaigunthEner Tek (P) Ltd. The fiberglass blades are exceptionally strong because they are denselypacked with glass reinforcing fibers that run the full length of the blade. The rotor has threeblades because three blades will run much smoother than rotors with two blades. DetailedSpecification of Rotor Blades are given in Details in Appendices 1.1

Generators

The generator is what converts the turning motion of a wind turbine's blades intoelectricity. Inside this component, coils of wire are rotated in a magnetic field to produceelectricity. Different generator designs produce either alternating current (AC) or direct current(DC), and they are available in a large range of output power ratings. The generator's rating,or size, is dependent on the length of the wind turbine's blades because longer blades capturemore energy.

Ener Tekgenerators are Brush less Permanent Magnet Alternator, normally usedin battery charging applicationsand Grid Connecting Application.

The battery Charging system use of an inverter, which converts DC to AC. Storagesystems using batteries store DC and usually are configured at voltages of between 12, 24 and120 volts,

The Grid Tied system use of Grid Tied inverter, which converts DC to AC to feedcurrent to Normal Grid Line, the configured DC voltages of between 140 Volt DC to 500 VoltDC. Details are in Appendices 1.1

Transmission: The numbers of revolutions per minute (rpm) of the Ener Tek wind turbinerotor are 500, 310, 240, 210, 167, 150 and 90 of AR-200W, AR-500W, AR-1000W, AR-2000W,AR-5000W, AR-7500W and AR-50000W respectively. As a result the Ener Tek wind turbinesrequire a gearbox transmission to increase the rotation of the generator to the speedsnecessary for efficient electricity production Except the AR-200W, AR-500W Model. The

technical details of Gear box is given in details Appendices 1.1

Nacelle

The Ener Teknacelle is the Aero Dynamic fiberglass housing around the main body ofthe machine. It contains the main structural of the turbine, slip-ring assembly, the yawbearings, and the tower mount. The yaw bearings allow the wind turbine to freely pivot aroundthe top of the tower so that the rotor will face into the wind. The slip-ring assembly is theelectrical connection between the moving (as it orients with the wind direction) wind turbineand the fixed tower wiring. The slip rings and yaw bearings are located just above the towermount.

Tail Assembly

The Ener Tektail assembly, composed of a tail boom and the tail fin, keeps the powerhead (Rotor) at perpendicular of the wind direction. The Tail Fin is made up of Fiberglassmaterial.

RPM Controller / Braking System

The Ener Teksystem working basic principles of Electromagnetic action of brake it iscontrollers the rotor RPM through rpm sensor. The rotor can be stopped under most windconditions using the Manual Barking (Electromagnetic) for the AR-1000W & AR-2000W, AR-5000W and AR-7500W systems. You might use this function, for example, before lowering or

climbing the tower. We do not recommend frequent use of the braking function because of theheat stress it puts on the alternator, particularly when the winds are strong.

Electrical Storage

Batteries are the most common form of electrical storage. Where heat, rather than

electricity, is the desired end product of a wind turbine application, hot water is the usualstorage medium. However, the advantageous economics of other heating systems make wind-powered heating a less attractive option.

Batteries can store and deliver only DC power. Unless an inverter is used to convert DC to AC,only DC appliances can be operated from the stored power. The battery voltage must be thesame as the voltage needed to run the appliance. Standard battery voltage is 12 or 24 volts.For Ener Tek system appliance requiring 24 volts Battery for AR-200W & AR-500W, 48 Volt or120 Volt Battery require for AR-1000W, AR-2000W, AR-5000W and AR-7500W. Batteryconversion efficiency is approximately 60% to 80%. A battery's capacity is rated in amp-hours, a measure of its ability to deliver certain amperage for a certain number of hours. Forexample, for a rating of 60 amp-hours, 3 amps can be delivered for 20 hours. Batteries shouldbe routinely inspected for fluid level and corrosion. The storage room should be wellventilated. If allowed to accumulate, the hydrogen gas produced by some batteries can

explode.

Charge Controller with Inverter:

The Charge controller (DC to DC Converter) will control charging current of the EnerTek Turbines. And it controllers Bypass on and off to maximize energy capture and preventbattery overcharge. The charge controller is microprocessor based smart controls determinesthese switching functions based on the battery bank voltage. At battery voltages below theregulation voltage the wind and solar are connected and allowed to charge the batteries. Atwind speeds below approximately 6 m/s the turbine LED (green) will blink slowly to indicatethat the controller is boosting the voltage from the turbine up to battery voltage. This low endboost function ensures that the maximum possible power is extracted from the turbine at lowwind speeds, and allows the turbine to produce power down to as low as 3 m/s under ideal

conditions. In higher winds the turbine produces enough voltage to charge the batteriesdirectly and the controller function is turned off. If the battery voltage rises above regulationvoltage the Extra Load (dump load) circuit is ramped up to control the battery.

The inverter output is 230-Volt AC with 50HZ frequencies; the inverter can be supplyeven 60 Hz also.

Dumb Load / Heat Storage

When the Batteries get fully charged the power is get divert to dumb load. The Dumbload is be either Water pump or Heating coils. The Dumb Load of Ener Tek System are 250 Watts heating coils for the AR-200W Model & 600 Watts heating coils for AR-500W systems.The 1-HP Water pump or 1200 Watts heating coils will be provide for the AR-1000W System,2000 Watts heating coils will be provide for the AR-2000W System & 5-HP Water pump Or6000 Watts Heating coils will be provide for AR-5000W system.10 KW heating coils will beprovide for the AR-7500 System

Grid Tied Turbine:

The grid tied Enertek Turbine Model has 4-Types of AR-1000W, AR-2000W, AR-5000W, AR-7500W and AR-50000W. The system out put from the DC TO DC Converter orBridge Rectifiers is 140 Volt DC to 500 Volt DC.

Tower: The smooth flow of the wind over the land is interrupted by obstructions andtopographical variations. These interruptions bring about two important phenomena: windshear and turbulence. Wind shear describes the fact that close to the ground the wind is

slowed down by friction and the influence of obstacles. Thus, wind speed is low close to theground and increases with increasing height above the ground. Wind shear is morepronounced over rough terrain and less pronounced over smooth terrain. Turbulence isessentially rough air caused by the wind passing over obstructions such as trees, buildings, orterrain features. Turbulent air reduces energy output and puts greater strain on the windturbine. The effects of both wind shear and turbulence diminish with height and can be largelyovercome simply by putting the machine sufficiently high above the ground. Taller towersusually will provide better economics because the power in the wind increases as the cube ofthe wind velocity (P = V3; e.g., a 26% increase in wind speed doubles the energy output). Asmall increase in average wind speed will result in a large increase in long-term energyoutput. Wind speed may increase more radically with tower height in hilly or wooded areas. Inflat open areas, power production will increase less significantly with tower height.

Our concerns are:

1) The forces on the turbine and mounting system are substantial and homes are notdesigned structurally for them.

2) The air flow around and over a home or building is complex and can causeconsiderable turbulence.

3) The wind turbine will cause vibrations that will be amplified through the homesstructure. Ener TekSystem offers a guyed-tubular and for AR-2000W, AR-5000W andAR-7500W system will have guyed tubular or self supporting tower, the self-supporting towers that do not require guy wires.

Wind Turbine Installation Procedure

The following information is intended as a set of checklists to assist our customers inaddressing the relevant details of an installation in logical sequences. Although most itemsapply to both large and small projects not every item will apply to every project. To insurethorough planning it is very important that the customer understand why a particular detail isor is not appropriate to the installation. By reviewing the entire list at various stages of theproject, the customer should be able to ensure that he/sheSitting Factors.

Site selection may have a significant effect on annual energy production. It is typicallyworth the additional time and effort to locate the proper site to maximize energy productionand maintain the wind turbine expected life. The following sitting factors should be considered

Wind Resource Characteristics

Annual average wind speed must be 4.5 m/s

Makeup of average (frequency and duration of power producing winds) Prevailing wind direction (s)

Turbulence

Peak wind speed

Height and location of obstructions

Distance from utility service point

Local restrictions relative to height, proximity to boundaries, etc.

Tower height

Proximity of wind turbines to each other

Site accessibility and its effect on construction and maintenance costs.

Permit and Approval

Many wind turbine locations will require some of the permits and approvals identifiedherein. It is important to determine which permits / approvals apply to your particular site.

Issued by:o Municipality or local councilo Countryo State or Provinceo Federal (FAA, FCC, etc.)o Commission (energy, conservation, historic, etc.)o Utility

Type:o Constructiono Foundation Engineeringo Electricalo Interconnectiono Communication Interference

Installation and Maintenance

In order to minimize the amount of steel and concrete used in the wind turbine, aguyed tower is normally adopted. In some circumstances, the tower will not require concretefoundations at all and soil anchors or rock bolts can secure the tower guy-cables to theground. This makes installation in remote regions easier because transportation of largeamounts of concrete is not required. Soil anchors or rock bolts are always load tested afterAviation Interference. For best performance, all wind turbine installations should be thoroughly

inspected by qualified personnel within 60 days after completion, atleast semi-annually, and

after any major windstorm, earthquake or other severe event. The inspection and serviceintervals identified by Vaigunth Ener Tek (P) Ltd Or its Agentsmust be followed for

any Vaigunth warranty to remain valid.

Non-tilting Towers:

Ener Tek system has non-tilting tower, such as a fixed guyed tower or a self-supporting pole type tower, there are two general approaches that can be used:

Page 8 of 22


9/22

Chennai

1) Assemble the tower and turbine together on the ground and then use a light - dutycrane to set the tower in place.

2) Erect the tower and then lift the wind turbine to the top with either a light-dutycrane or a gin-pole.

A gin-pole, in this case, is a tower assembly tool that attaches to the tower andprovides an arm with a pulley so that parts can be hoisted above the top of the tower.Professional tower erectors use gin-poles and we do not recommend their use by non-

professionals. Wherever possible we strongly recommend assembling the tower andturbine on the ground. When raising the tower you must lift the tower, not the EnerTek wind turbine. The Ener Tek cannot support the weight of the tower. Forcustomers installing a Ener Tekon an existing fixed tower we recommend that youuse a crane to lower the tower so that you can attach the turbine on the ground.Alternatively, we recommend you use a bucket-truck, like the type used by utilitylinemen. If neither of these approaches is possible then we recommend that youengage the services of professional wind turbine or tower erectors to install your windturbine.

Procedure Of Ener Tek Installation

Step 1: With the tower tilted down, place the wind turbine near the top end of the tower. Thetower wiring is connected to the Ener Tekwind turbine at the slip ring using two small screws

and ring terminals crimped to the two conductors. Cut the outer insulation on the wire backabout 60 mm. Strip the insulation off the outer 12 mm of each conductor and crimp on theappropriate ring terminals. Attach the two power conductors to the slip-ring assembly with thescrews provided. The polarities of the connections are marked. If your conductors are color-coded we recommend making note of the colors connected to positive and negative leads. Theslip ring assembly is not designed to support the weight of the down-tower wire. If possibleput a loop in each wire to wrap around the wire ties. Use the two nylon cable ties provided tosecure the tower wiring to the tower adapter casting. After completing the connections, pull onthe tower wire to make sure that it is secure before mounting the wind turbine on the tower.

Step 2: Raise the tower about 1 meter off the ground to provide room to assemble for the AR-200W, AR-500W turbines, But for AR-1000W & AR-5000W turbine raise about 2 Metter and2.5 Meters respectively. We recommend fashioning a temporary support stand to hold thetower up during turbine assembly.

Step 3: Mount the wind turbine tower adapter to the top of the tower using the given boltsand six washers. We strongly recommend applying Loctite 270 (Thread Locking Compound) tothe threads prior to installation to reduce the likelihood of loosening due to vibration. Werecommend using a torque wrench to achieve the proper fastener torque on the towermounting bolts. The recommended torque is 40 N.M for AR-200W & AR-500W and 54-N-M forAR-1000W, AR-2000W,AR-5000W, AR-7500W and AR-50000W.

Step 4: Complete the turbine wiring to the Controller before adding the blades. This isrecommended so that you can test the DC polarity of the wiring by spinning the alternator byhand. It is very important that the polarity [positive (+) and negative (-)] is correct when theturbine is connected to the Controller. The best way to ensure this is to complete the wiringand then test the polarity with a Volt-Ohm-Meter. Carefully mark the positive and negativeelectrical leads for later reference. We recommend that you can use the Stop Mode (By ManualBrake) to keep the blades from turning during the turbine and tower raising process.

Step 5: Bolt the tail fin to the tail plate using the given bolts and washers for the 4-Ener Tekmodels. We recommend applying Loctite to the bolt threads prior to assembly.

Step 6: Place the tail Plate on the rear of the turbine head and given Bolt with washer. Werecommend applying Loctite to the bolt threads prior to assembly.

Step 7: Attach the blades through the given Bolds & Washers; do not forget to put lock nut.We recommend bolting one blade up solidly and leaving the other two somewhat loose while

Page 9 of 22

you check the tip-to-tip blade distance. We recommend checking, and adjusting as necessary,the blade tip spacing to ensure that the blade tips are equally spaced. This step will help makethe wind turbine as smooth running as possible, which will maximize the operating life of thebearings and reduce vibration related noise. The blade tip-to-tip distances should not differ bymore than 8 mm for smooth operation. We recommend using a torque wrench to achieve theproper fastener torque on the blade nuts. The recommended toque is 40 N.M for AR-200W &AR-500W and 54-N-M for AR-1000W, AR-2000W, AR-5000W, AR-7500W AR-5000W. Loctite

is not necessary on the blade fasteners because the locking nuts provide adequate locking.

Step 8: Attach the spinner (nose cone) using the given bolts and washers provided. Werecommend applying Loctite to the bolt threads prior to assembly.

Step 9: Raise the tower following the procedures outlined by the tower supplier. Pleasemake safety your top priority.
