1.0 Definition of Transformer: A Transformer is a static electric device that transfers electrical power from the primary winding to the secondary winding using electromagnetic induction. Transformers can raise or lower the voltage with conforming drop or rise in current. Transformers work on the value of mutual induction. When two coils are positioned so that the flux produced by one coil links to the other coil, then by fluctuating current in one coil the electromagnetic field is induced
5.4. Protection of Power Transformer The protection system of the transformer could be classified as electrical and non electrical protection. The electrical protection means the working principle of the protection based on the current, voltage, or frequency of that appear on the protected zone. The non electrical protection will operate based on the physical conditions of the transformer and the insulation media. These physical conditions could be temperature, air (gas) in
Preview On nearly every wall hangs a giant poster of stunning Transformers-themed concept artwork. There are a lot of walls in High Moon Studio's warehouse-filling offices. The staggering amount of concept work the developer has done for their upcoming game must be some kind of world record. In one corner, a programmer is adding a few lines of code to the game, while at the same time watching VHS tapes of the original 80s Transformers cartoon. Every cubicle is filled to the brim with toys, memorabilia
Introduction: Transformers are widely used in power systems and it is considered as the most essential component of every power system. A transformer is a static device that works on Faraday’s law of electromagnetic induction and it is used to transfer electrical energy from one circuit to another or in other words it is a device which is used for decreasing or increasing the voltage of an alternating current. Basically there are two types of transformer i.e. step up and step down transformer but in general
Most substation transformer failures, excluding acts of man or nature, can often be traced to poor maintenance of the transformer or its related components. Catastrophic failure of a substation transformer can be prevented by accurately testing the condition of the oil on a yearly basis and by having a monthly visual inspection program in place. Most of the checks on a substation transformer are relatively simple: checks for oil leaks, oil level, temperature, the operation of the on-load tap-changer
Transformers: More Than Meets The Eye When I was younger, I loved to watch cartoons. Although I watched many cartoons, there was one cartoon in particular that caught my attention the most. This cartoon was a science fiction story about robotic lifeforms called The Transformers. At that time, The Transformers was the most exciting and important thing in my life. It came on everyday, and I tried not to ever miss an episode. If I knew I would miss an episode, I made sure I had someone record it for

Transformers: Dark of The Moon, was an exceptional movie. The movie is about a group of aliens from a planet called Cybertron coming to take refuge in Earth. Directed by Micheal Bay . In this movie, a civil war broke out in a foreign planet Cybertron between the autobots and the decepticons. And in order to rebuild what was destroyed someone has betrayed their side .It is an action movie with a great soundtrack and I really like how in like every movie they play “Linkin Park”. The direction was
To trace the energy of an electron from the time it enters the x-ray circuit until it’s converted to light, start with a standard U.S. 60-HZ AC (alternating current) wall circuit with a nominal root mean square (rms) voltage of 220. An alternating current is created by, electrons moving in one direction and then reversing to move in the opposite direction. Because of this process in electron motion the AC is constantly establishing, collapsing, reestablishing, and re-collapsing its surrounding magnetic
lightning. I sought out to harness the same power possessed by Zeus by following in the footsteps of Nikola Tesla, arguably the most influential and underrated scientist and engineer in modern history. One of the inventions he created was a resonate transformer that converts low-frequency energy to high-frequency energy in hopes of one day having wireless energy for all. This sparked my interest in building a Tesla Coil. At the genesis of the idea, I did not have any experience with electricity or engineering
Voltage stability is defined as the ability of a system to restore steady voltages at all buses in the power system after being exposed by any disturbance from a given initial operating conditions. Voltage stability purely depends on the capability to maintain equilibrium between load supply and load demand from the consumer end. When there will be any progressive fall or rise of voltages of some buses that can cause instability. Power system stability is expressed by the capability of a power system
was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer. Faraday continued his
phenomenon of internal winding fault which produces internally has deep effect on the lifetime of a transformer [58]. This kind of faults will lead to generated heat in the faulted region of the winding. Therefore, this generated heat will cause the fault to step rapidly to more critical forms, such as phase-to-phase and phase-to-ground faults [59] [60]. The internal short circuit currents of transformer may be larger than its terminal short circuit currents [61]. These faults will result in downtime
Auto-transformers, step-up transformers, and step-down transformers use electromagnetic induction to change currents therefore being able to produce kVp, mAs, and DC current using rectifiers when it comes to x-rays. The following paper will describe in brief detail a little of Michael Faraday’s life, how electromagnetic induction came about, how MRI uses electromagnetic induction to function, and an explanation on how auto-transformers, step-up transformers, and step-down transformers work and
Anyone can wire a doorbell if he follows these steps and safety precautions. Modern day doorbells use transformers to supply power to the circuit. One can wire up a doorbell if they use safety precautions, follow instructions,and the proper materials to wire it with. Take safety precautions by using the correct tools which includes screwdrivers,wire strippers,electrical contact cleaner, fine sandpaper, rubbing alcohol, and a cotton swab or old toothbrush although door bells don’t use much voltage
“Little by little one walks far.” - A Peruvian proverb When I was ten, on watching the building elevator move up and down, I tried to create a small toy elevator using the motor and remote control of a toy car. I suspended the toy lift with threads on my room’s window, put my little GI Joe figurines in it, and made them move up and down. Later in school, I developed interest in Physics and Mathematics. Meanwhile, in my junior college of Science, I got an excellent exposure to most of the concepts

Ever since my days in middle school in China, I have dreamed of being an electrical engineer. My father nurtured my copious ideas such as transformer and inductor. Even though I didn’t have too much idea about electrical engineering, I found abundant happiness though work activities that included practical and hand-on problems. During the past three years, I learned a lot concept including semiconductor, electromagnetic and signal at University of Illinois. I have explored ECE widely and eventually
heat generated in the element is directly proportional to the current which depends on the magnetic flux. So heat is indirectly controlled by the magnetic flux. Our aim is to vary the magnetic flux. This process is similar to that of a transformer. In a transformer current is controlled by voltage. Similar to t... ... middle of paper ... ...nstruction and is very costly. Older controlling techniques use 16 pulse or 8 pulse rectifiers which are now replaced by 24 pulse rectifiers, which makes it
coupling SEPIC converter compactable. One practical limitation of SEPIC converter is duty cycle should not be high because if duty cycle close to unity the static gain goes to infinity. To replaced L2 to mutual inductance which will acts as flyback transformer and its turns ratio increase the gain of the converter. But use mutual inductance developed reverse recovery
