Q:Variable High Frequency High Voltage Power-supply /transformer, possible?
The Tesla coil needs to operate at the same resonant frequency on both the primary and secondary sides of the loosely coupled transformer. The resonant frequency is set by the inductance and capacitance of each side. The problem is there are no high voltage solid state capacitors (varactor diodes like you see in r.f. receivers that adjust the tank circuit frequency) on the primary side, and no way to adjust the top hat toroid capacitor on the secondary side (unless maybe it was a mylar covered balloon with vacuum deposited aluminum that could be remotely inflated or deflated). So you are stuck with whatever high voltage capacitor and toroid top hat you have on hand, and the inductance of the coils you wind that ends up being the resonant frequency. Even then it takes a lot of fiddling to get both in tune to give the maximum voltage output. The input frequency to the primary coil (the 555 circuit used in the step up with the flyback transformer- its frequency was chosen solely due to the flyback's frequency design) has little to do with the primary's resonant frequency; again that is set by the capacitor used and the size and number of turns of the primary coil.
Q:Transformers The Movie 1986 Or Michael Bays Transformers?
The 1986 version has better acting on the part of the voice actors, more caring tragedy, more likable Transformers, very atmospheric, and one of the most tragic death's in the history of robot-kind. The first Transformers movie was stupid but fun. The acting in it was okay, the story was incompetent in the fact that they did not explain as much as they could have, bitchy lead actors, and a pretty epic final battle scene. The second Transformers movie is god awful. It is racist, the story is copied from the first movie, the acting is horrid, the characters are bloated bitches that yell all the time, a horrid villain(s), an overactively preachy Optimus Prime, a horrid Optimus death by unknown Decepticon, Transformer balls, bad dirty jokes, Shi Labeouf in robot heaven, Shi Labeouf having a near seizure, Shi Labeouf's mom gets high, and one of the longest unneeded battle scenes in movie history. The third Transformers movie is a step above god awful, racist towards Asians, the story is copied from the first two, the acting is still horrid, Shi Labeouf is self obsessed, Shi Labeouf is mean (he kicked Bumblebee), the Decepticons are cooler but the Autobots are the same, Optimus is still overactively preachy, a blinking camera during the final fight, a horrid Megatron death, a decent twist with Sentinel Prime, bad dirty jokes, Bumblebee getting tickled, a better and prettier actress than Megan Fox, and one of the worst guest appearances in movie history (Leonard Nimoy). C Y I like the old one better. Which do you like better? Also the new Harry Potter has a 100% from all critics.
Q:Transformers are divided into several. What is the role of each? To be specific!
Transformer is the instrument that regulates voltage! Transformers can be classified according to their operating frequency, use and core shape. (1) Classification by operating frequency Transformers according to the operating frequency can be divided into high-frequency transformers, IF transformers and low-frequency transformers.
Q:How to make a current transformer more linear?
There could be eddy currents in a poorly designed transformer, yet sensible transformer cores are produced from laminated iron so as that the present can't circulate around the middle. you do no longer choose the middle to appear as if a shorted turn on the transformer. inspite of out eddy cutting-edge loss, there nonetheless is capability loss interior the middle that equals the part of the B-H loop according to cycle of ability.
Q:why are power transformers rated by KVA(kilovolt- ampere) instead of kilowatts?
well from what my teacher told us kilowatts is reserved for real average power. As you know inductors and capacitors have no average power which means that the power in those elements are just being recycled over and over again. for sinusoidal steady state this power is imaginary (mathematically) and is giving the kVA. It's just terminology.
Q:Transformer Efficiency Question?
Transformer efficiency (usually between 85 to 98 percent) is more of a function of transferring power, I x E or I^2 x R. Usually with the transformer's secondary looking into some kind of Load. So, you would say that transformer efficiency is a function of (Ps / Pp) x 100, or [I x Es (rms) / I x Ep (rms)] x 100 effiiciency of the transformer. Efficiency factor affects both votlage and current (power) in exactly the same way.
Q:in which sequence should i watch transformers?
1) In the G1 timeline we have a sequel series made exclusively for Japanese audiences. They completely ignore the events in the American ending and go in a completely different direction. 1) Transformers: Headmasters 2) Transformers: Super-God Masterforce 3) Transformers: Victory 4) Transformers: Zone Then there's Beast Wars and Beast Machines is a sequel/prequel to the G1 series. ___________________________ 2) Transformers: Robots in Disguise (RiD) aka Transfomers: Car Robots in Japan is a complete standalone series, no relation to any other existing TF series ____________________________ 3) The Unicron Trilogy is it's own timeline that has 3 series. US - JP Armada - Micron Legend Energon - Superlink Cybertron - Galaxy Force but the 3rd series, Cybertron, was originally a self-contained series, the American version edits the dialogue to make it appear as a sequel to Armada and Energon. Also, the character Override, who is female in the US version, is male in the Japanese. In other words in Japan the first 2 are in the same continuity and the 3rd is a another reboot.
Q:Low volts transformer question?
you need a transformer that will support the 12volts lamps and still connect to the 120volt outlet. the best suggestion is to go to the Radio Shack and talk to the counter dude for help --- or --- go to the garden lighting section at Lowe's etc, for
Q:How can I ground a 208v/120v control transformer ? should I just connect x2 terminal to ground?
I am thinking that your incoming power is 208 volts and you want to convert to 120 volts. If i haven't made myself look foolish, you merely need to use your x1 and x2 wires to continue on as your 120 volt power source. Cap off, do not connect/use the other connections involved on your multi tap transformer. If I have the idea wrong.never mind what i said. To ground the transformer, truly grounded? you need to connect the metal, unpowered shell to a ground. If you mean make a neutral/ground, you don't.
Q:2500KVA transformer bearing current how much calculation
2500KVA transformer carrying current of 7740A. The calculation method is: Because P = UIcosφ, so I = P / (Ucos?) = 2500 KVA / (380 Vx0.85) = 7740A. Transformer is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: power transformers and special transformers (electric furnace change, rectification, frequency test transformer, voltage regulator, mine variable, audio transformers, IF transformers.
