WIRE DIAGRAMS STARTING MOTOR USING AUTO-TRANSFORMATOR

Wire Diagrams Starting Motor Using Auto-Transformer - In the starting mode, the initial voltage supplied to the motor through a reduction autotransformator and after a few seconds the motor steady speed is reached, the voltage to the motor stator terminal voltage value is returned to positions normally through displacement contact circuit as shown in the picture below.

Wire Diagrams Starting Motor Using Auto-Transformer

The process that occurs on the motor with autotransformator starting mode consists of three stages as follows:

Stage One

when subjected to early start the motor terminal voltage supply whose value has been reduced because the flow of power to the motor is passed through a autotransformator connected in star. The amount of reduction in the voltage applied to the motor depending on the position of tapping on the autotransformator rolls.

Stage Two

after the motor spins while, contactors that form the star relationship autransformator detachable, so the auto transformer will form a series inductance in series with the motor, in this case actually rolls the autotrasnformator form a series inductor series with the stator windings. Usually the transfer of the first stage to the second stage will be to work after a few seconds the motor rotates.

Third Stage

a split second after the second stage, the circuit will move ketahap third. At this stage supply voltage the motor gets in full accordance with the voltage nets - nets. When the contactor which sends a full supply voltage to the motor terminals is active, then indirectly autotransformator ter-bypass so that the existence autotrasnformator not affect the value of the supply voltage towards the motor. And if the motor has been operating normally, autotransformator can be turned off.

Starting the system with this mode is typically used on LV motors with power above 150kW. Disadvantages of this system is the cost is quite expensive because of the high cost for a autotransformator.

Easy enough right? 3RDi HD camera equipped with the ability to record up to 1080p resolution with wide view mode.

This device is compatible with Android and iOS. And reminds us of Google Glass that has similar functionality but with more complex features. 3RDi the model itself is not bad and suitable for use as an accessory, but the concept was introduced models try not to everyone's taste, especially for men, because too flashy camera in munculkan by the Headband. In contrast to what Google Glass tried to offer a more elegant and classy, especially the camera features a slightly disguised.

FACEBOOK RELEASE TELEPORTATIONS TOOL IN 2025

Facebook Release Teleportation Tool In 2025 - Technology continues to grow rapidly, communication technology is also growing rapidly. Communication tools such as mobile phones or who currently has mushroomed is a smartphone has become a trend and lifestyle, because the more cheap and easy to obtain smartphone. But the trend does not just stop human communication to voice communication only. Mike Schroepfer as Head Technician Facebook recently revealed a plan to make human nanar communication easier and a lot of aspects that can be reached, the tool teleportation. In a statement, Schroepfer said "Facebook wants to build a tool that lets anyone can go to the desired place with the exclusion of geographic boundaries." It is said, means of teleportation will be completed in 10 years, which is expected to be introduced to the public in 2025.

Facebook Release Teleportation Tool In 2025

Unfortunately, teleportation tool is not as teleportation tools that exist in science fiction films, which can move a person from one place to another in an instant. Transport equipment developed based on Virtual Reality Facebook, the Oculus. Mike Schroepfer give you an idea, Oculus will be able to make the user think the virtual world is real, imitating the world in real-time and allows users to realize the imagination in 3D. In other words, the virtual world who want carried Facebook will not feel fake as it is today. One of the great challenges that make the virtual world feels real is it possible to see oneself, for example, saw a hand or other body parts. Hmm, seemed steeped in the movie The Matrix or Inception.

Very interesting would plan to make up the teleportation tool. The future will definitely be a lot of development and institution or other scientists who will meyempurnakan concept and idea of this Facebook artificial Teleportation. And it is not likely one will be found when the actual teleportation tool menindahkan people to the desired place in an instant.

METALLIC SHEATHING IN POWER CABLE TECHNOLOGY

Metallic Sheathing In Power Cable Technology - metallic sheating is provided over the paper isulation and should have intimate contact with the external layer of insulation. the metallic layer provided must be electrically contionous. thus, the sheath used not only provide waterproof protection, but also provides an electrical earth shield the potential of which is zero and the potential of the conductor is reffered to this.

Metallic Sheathing In Power Cable Technology

the metallic sheath used may be either of lead or lead alloy or of aluminium.

Lead and lead alloy

are the mostly used materials as the facilitate the manufacturing of cables and is pliable. also lead is generally immune to corrosion except under secial conditions (by electrolytic action and organic acids). however, lead may crack due to inter-crystalline corrosian and vibration. it has been observaed that the cables laid underground where heavy traffic passes and near the railway lines, bridges etc. the cables fail due to such cracks.

Aluminium Sheath

In recent years aluminium has also been used a sheath, since it decreases the weight of the cable (lead is about four times heavier than aluminium) and its conductivity is about seven times that of lead which make such cable much adaptable for mining works. It may be pointed out that the sheath loss increases due to increases in sheath current. the current rating for the multicored aluminium sheathed cables is the same as that for lead-sheathed cables for the same conductor temperature but the single core aluminium sheathed cables used on a.c system are derated due to increase in sheath current.

The following are the advantages of the aluminium sheathed cables over the lead sheathed cables:

Increase in the tensile strenght.
The Weight is decreased which facilitates in handling of the cable in its installation.
since the cable is of light weight, so the fixtures will also be light.
The cable is free of cracking due to vibration etc.
It improves the mechanical properties of the cable and reduces the need of heavy armouring.

Sometimes with lead sheathed cables an earth continouly conductor is run which is in good contact with the sheath throught its length to ensure adequate earthing.

CABLE INSULATION IN POWER CABLE TECHNOLOGY

Cable Insulation In Power Cable Technology - Cable is a medium to deliver electrical energy. in an electrical wiring generally consists of an insulator and a conductor. Isolator is a cable wrapping material is generally made of plastic, while the conductor is made of copper or aluminum.

Cable Insulation In Power Cable Technology

Cables are usually classified according to the type of insulation used. the type of insulation to be used must have the following properties:

it should have specific resistance.
it should have high dielectric strength
it should be tough and flexible.
it should not be hygro:copic i.e. it should not absord moisture from air or surroundings.
it should be capable of standing high temperatures without much deterioration.
it should be non-inflamable.
it should not be attacked by acids or alkalies.
it should be capable of withstanding high rupturing voltage.

Althought it is not possible to have all the above mentioned qualities in one particular type of insulation. the selectionof a particular type of insulation to be used is dependent upon the purpose for wich the cable is required and qualities of the insulation to be aimed at. the following are the chief types of insulation groups wich can be used:

Rubber.
Polyethylene.
polvinyl chloride (P.V.C)
Fibrous material such as paper or jute.
Vulcanized bitumen.
Gutta-percha.
Silk, Cotton, enamel.

Rubber

Rubber is the most commonly used insulation in cables. Rubber has a dielectric constant between 2 and 3, dielectric stress is 350 kV/cm. approximately, and spesific resistance of 10^17 Ohm/cm. It absorbs moisture slightly and the maximum safe temperature is approx. 38 C. So, pure rubber cannot be used as an insulation since it cannot withstand high temperatures and cannot be put to rough usage, being too soft. Thus, mostly the rubber used as an insulation on wires consists of 20 to 40 per cent of India rubber, the remainder being mineral matter such as zinc oxide, red lead etc. also a little bit of sulphur is added. the method of applying insulation is given below.

Polythylene

It is thermoplatic synthetic resin and has very good dielectric and ageing properties. it is a tough and flexible material having exelent electrical and mechanical properties as an insulating material. It has a dielectric strength of 400 kV per cm. Polyethelene is non-imflamable material. Even if a flame is continously applied to the polyethylene. the buraing will stop after a burning will stop after a few oms. away from the flame. due to threre proporties it is being extensively used as an insulation.

Polyvinyl-Chloride

It is a thermo-plastic synthetic resin and is being widely used as an insulation. it has high electrical resistivity, good dielectric strenght and mechanical toughness over a wide range of temperture. moistures acids and alkalies do not affect P.V.C. insulated cables are usually employed for medium and low voltage domestic industrial lights and power instalations.

Paper
paper insulation in power cable has almost superseded the rubber insulation. the foremost reason of this is that it is quite cheap and has low capacitance and high dielectric strength.

CABLE COSTRUCTION IN POWER CABLE TECHNOLOGY

Cable Construction In Power Cable Technology - Cable is a medium to deliver electrical energy. in an electrical wiring generally consists of an insulator and a conductor. Isolator is a cable wrapping material is generally made of plastic, while the conductor is made of copper or aluminum.

Cable Construction In Power Cable Technology

The ability of the electrical conductivity of the cable is determined by CRC (current-carrying capability) has, where electrical conductivity parameters specified in units of Ampere. Current-carrying capability is determined by the cross sectional area of the conductor that is in electrical wiring.

The general construction of the cable is given below:

Core, All cable have one central core or a number of cores of stranded copper or aluminium conductors having highes conductivity. Generally there are one, twoe, three or four cores.
Insulation, THe different insulation used to insulate the conductors are paper, varnished cambric and vulcanized bitumen for low voltage, but mostly impregnated paper is used which is an excellent insulating material. when vernished cambric is used as an insulating material (for low voltage cables) petroleum jelly is aplied between the alyes of the cambric tape wich prevents demage to the insulating tape due friction when the cable are handled.
Metalic Sheath. A metalic sheath is provided over the insulation so as to prevent the entry of moisture into the insulating material. The metalic sheath usually of lead or lead alloy and in case of cables having copper as conductor sometimes aluminium is also used for providing metalic sheath.
Bedding, Over the metalic sheath comes a layer of bedding wich consists of paper tape compounded with a fibrous material. also sometimes jute strands or hessian tape (Strong coarse cloth of hemp or jute) is also used for bedding. the purpose of providing the bedding is to protect the metalic sheath from mechanical injury for the armouring.
Armouring. Armouring is provided to avoid mechanical injury to the cable and it consists of one or two layers ofgalvanised steel wires or two layers of steel tape.
Serving, Over and above armouring a layer of fibrous material is again provided which is similar to that of bedding but is called as serving.

HOW THE PROCESS OF MANUFACTURE OF ELECTRIC MOTORS

How the process of manufacture of electric motors - Today I will share how to process the electric motor is produced. for those of you who do not know what the bike, I will give a little knowledge. The electric motor is a tool that serves to convert electrical energy into mechanical energy. Electric motors used in home appliances such as fans, washing machines, water pumps and vacuum cleaner. in addition to the electric motor is also used in the industrial world as a weight lifter, pengengkut load on conveyors and others.

How the process of manufacturre of electric motors

Electric motor consists of diverse types and type. All kinds of electric motors has two main parts: the stator and the rotor, stator is the stationary part of the electric motor and the rotor is part of an electric motor that moves (spins). Based on the work voltage source is used, the electric motor can be divided into 2 types:

Direct current electric motor
alternating current electric motor

Working Principles

In the electric motor, electrical energy is converted into mechanical energy. This repair is done through a process of induction or commonly referred to as an electro magnet. poles of a magnet that will repel namesake and poles are not namesake, attraction. Then we can get the movement if we put a magnet on a rotatable shaft, and the other magnet in a fixed position.

actual manufacture of electric motors can also be assembled, but the results of the motor assembly is very simple so it can not be used in large power. Now I will share the process of making the bike itself is done at the company. where these motors can be used for heavy loads.

FANS "AVENGERS" CREATED A LASER HAND IN STYLE OF "IRON MAN"

Fans "Avengers" Created A Laser Hand In Style Of "Iron Man" - Fans most creative 'Iron Man', perhaps that is what was shown by Patrick Priebe. This man has just uploaded a demo video of the laser beam pemendar tool palms ala Iron Man. Appears on the video that it is capable of issuing two different laser light from the palms and backs of hands. Not only that, the tool is able to throw a kind of 'bullet' shaped metal plate on the back of the hand.

Fans "Avengers" Created A Laser Hand In Style Of "Iron Man"

Interesting side 'toy' is located on the second laser beam laser. Blue laser beam has a power 700MW, while the red laser beam power 300mW. Enough power to burn wood, but of course still less strong against the enemy Iron Man sort of Ultron. Gadgets are very creative, especially when he heard the sound of palms turned on the laser is very typical of Iron Man. Curious? Consider just the following video.

ALTHOUGH NOT PERFECT, TESLA AUTOPILOT RELEASED TO PUBLIC

Although Not Perfect, Tesla Autopilot Released To Public - When other car manufacturers are testing autonomous car, or a car that can drive itself without the presence of the driver inside, Tesla was already offered to the public for their own driving mode. Yup, "Tesla Autopilot" is the name of this project, and has been presented by Tesla's Model S through the latest version 7.0 software update.

Although Not Perfect, Tesla Autopilot Released To Public

In the Tesla Model S, Tesla Autopilot function uses ultrasonic sensors as detection. Supporting tool is the camera, radar, ultrasonic and satellite captured positions. So the Model S will be guided by the ultrasonic sensors totaling 12 pieces that can spread as far as the radius of 16 feet in each direction. The sensor is also supported with electronic brake assistance device digital precision.

Although innovation is quite sophisticated, but Tesla himself confirms Bahwan This mode does not guarantee 100% secure. So you still need to remain alert your hands near the steering wheel. Some owners of the Tesla Model S start practicing this Autopilot, and documenting via video.

In the following YouTube channel Tesla Model S very promising performance dengen Tesla Autopilot mode. This car can be on track and be able to put the brakes on when there is a change of pace at the front of the car, after which he can accelerate by itself. To change the lane was only by activating the turn signal lights to the right or left, then the car will detect whether there is interference or not, after that the car changed lanes.

However, in other trials, especially for driving on the highway, sometimes Tesla Model S moves pretty extreme off track, it is certainly quite dangerous. As on account RockTreeStar channel, the Model S was tested at the national road and so there is a car opposing directions, the car moved suddenly towards the opponent's car. This makes the driver reflexes shocked and immediately turn the wheel to mengghindari collision, fortunately the situation can still be controlled.

Tesla itself says that Tesla Autopilot mode is still in the development stage so if you want to use it you must be extra careful. Hands still must remain alert at the wheel, and it seems you can only use it on the highway alone with no road markings, such as Cruise Control mode on the current car. But at least the breakthrough Tesla Autopilot made a breakthrough technology that will better Autonomous Driver in the future. How, interested in Tesla Autopilot? Do not forget to check out the price of the car Tesla Model S.

DARK PURPLE, FLASH DRIVE CRUSHER PC

Dark Purple, flash drive crusher PC - Flash drive become very familiar today, as the data storage media is highly portable, flash provides mobility and efficiency in use. Introduce Dark Purple, a unique flash made by the team of researchers from Russia. The uniqueness of the flash is not due to the shape, model or capacity, but because of the threat their role. Yes, this flash is very dangerous because it can make our computer, be it a PC or laptop permanently damaged alias will not be used again.

Dark Purple, flash drive crusher PC

Dark Purple will damage our computer motherboard, so it can not be used at all. Fortunately -If you could say so- kerusakana motherboard is only attack alone. So by replacing the motherboard, the computer will return to normal without disturbing data on the hard drive. But to replace the motherboard is certainly not easy and cheap is not it? Especially on laptops.What's wrong with this stick, so so ferociously could be lethal or damaging our computer? It was from within this flash flow high current of 220 volts, the voltage is similar to a home. This current is supplied via the USB so it can directly damage the motherboard and the computer can not be used any longer. Voltage of 220 volts is generated from the conversion of the input voltage of 5 volts to 220 volts, similar to the inverter circuit, 12 Volt input turns into 220/240 Volt output. Wow really sophisticated yes, with a small chip that can generate a large enough voltage!

In a video, they show how an IBM Thinkpad laptop directly to death, just after the flash is plugged into its USB port. The research team also claimed, this attack was not just for desktop or notebook computers, but any device that has a USB connection such as Smart TVs, LCD monitors, smartphone or even a car head unit

ADVANTAGES AND DISADVANTAGES OF WIRELESS TECHNOLOGY

Advantages and disadvantages of wireless technology - Wireless technology is an electromagnetic transmission medium that does not require a cable that is emitted through the medium of the air by a wave frequencies that can be used by the satellite, infrared rays, as well as satellites. With the wireless technology make people more easy to do things with distances though.

Advantages and disadvantages of wireless technology

This technology is typically used in the network between buildings, between houses, between countries that have long distances even with using the Internet. So in this modern age of wireless or wireless technology is needed. But not only used for inter-building networks alone, wireless technology has also been applied in various devices as an example currently circulating various brands of wireless mouse, wireless keyboard, and more.

By using these technologies will certainly facilitate the use and maximize use. Because users are not bound by the limits of the cable, so that it can be used within a certain distance of approximately 10 meters. Wireless technology on mouse or keyboard using a conductor chip that is useful to connect the devices between the mouse with your PC or laptop.

In addition the technology is also applied to the WiFi network that allows users to access the Internet without using a LAN cable while it is in range. But with all the ease of wireless technology also have some problems or deficiencies that often occur. To discuss more about what are the advantages of wireless technology and what are the drawbacks? Listen to the discussion below!

The following advantages and disadvantages of wireless technology:

Wireless technology advantages

Wireless technology really allows a network to reach locations that could not be achieved by using a network cable.
With the wireless system can provide the user with various access information in real-time anywhere. Given this extremely supportive in productivity and an increase in kualias than using a wired network.
Next advantages is the ease of installation. You do not necessarily need a cable to connect two or more computers. Then the installation process it will be much easier and lighter without stalling cable or perforate the wall.
A wireless LAN system can be configured with a variety of network topologies to meet the needs of the user. Himself the configuration can be changed from peer to peer with a small number of users to full infrastructure networks with up to thousands of users, and so allows for roaming in a large area.

Disadvantages Wireless

Interference in the wave of tissue that could occur anytime. Disorders-disorders can be caused by weather or other disruptions.
Disruption to security. Often the information accessed via the wireless network when entering information in the Internet network bersiko it can be accessed by others. Therefore, the security configuration such as unique password should be given. As well as the use of antivirus security to protect your privacy

Thus the earlier discussion of some of the advantages of wireless technology and its shortcomings. With all the convenience that each technology has its own shortcomings as well as wireless technology.

JAPAN MADE A CLASSIC ORIGAMI BIRD-SHAPED DRONE

Japan made a classic origami bird-shaped drone - If the bird fly paper or so-called origami is indeed impossible, but origami birds able to fly if it has been modified into drones. During this time we are shown drone shaped rigid with four blades or more. However, the drone has a new innovation in shape.

Japan made a classic origami bird-shaped drone

Introduce this origami bird-shaped drone named Orizuru. This unique company behind the drone is capable of implementing ROHM Semiconductor drone technology in the form of origami birds. Orizuru itself has been exhibited at the event in the Combined Exhibition of Advanced Technologies, held in Tokyo, Japan.

Orizuru itself able to fly because mengepakan two wings like a real bird, with a wing mengepakan left and right, Orizuru able to fly in the air like drones in general. They claim that Orizuru have a high level of power efficiency, making it could be longer fly.

To control Orizuru itself is still the same with the other drones, which use a remote to control remotely. This drone replicate the actual style of flapping birds, while flying in the air when the drone also appears to look like a real bird.

Drone with a size of 70 cm is also equipped with a sensor like drones in general.

Innovations developed by ROHM Semiconductor solely to attract consumers with a unique form of drones. The use of drones in Japan itself is an illegal, because civil society can control the UAV in the centers of government or politics.

In April alone, there was a man to fly a drone over the building known rejected on nuclear energy policy proclaimed pemerinatah Japan, Prime Minister Shinzo Abe. At the drones carrying radioactive sand and want to drop it on the roof of the building. Therefore, after the Japanese government considers the drones as illegal goods in July.
