- Q: If defects of one phase transformers can be improved by 3 phase transformer,then why not a 4 phase transformer used
- What I see in the other answers look basically correct. There is a video on the General Electric website where a researcher tried transmissions of many types; all the way up to twelve phases. As already said; the advantage is quickly lost above three. Try the Edison Tech Center, Lionel Barthold, and also Steinmetz. For Reference.
- Q: I'd recommend a big Transformers fan for this please. So I have a Transformers series that I'm working on for fun, and I want an awesome name for it. It has Unicron in it and the Autobots and Decepticons team up to take him down. A name for that part is Cybertron Alliance. But I also need a name for story with events that take place before that, when the Bots and Cons were at war. Please help!
- You can't do that, you didn't make Transformers. Michael Bay would have asked could he add some of the characters into his movie. Like they would have asked J.K Rowling could they do Harry Potter Movies.
- Q: does anywon kno if michael bay will bring back any robots that died from his previous movies? like jazz or bonecrusher or brawl anything like that. and i know that their making transformers 3 but does anyone know whats its going to be called or what are some new transformers? thank u for all ur answers. exept the crappy wons. il just delet thos. even tho u cant. ???
- Okay let me start off by saying i'm not a nerd i just love transformers. lol. But from what I've heard the title is Transformers: Ascendents of Cybertron. The main villian is Shockwave. Megatron, Starscream and Soundwave are the only three that have been confirmed to be in the third one as of now. For the autobots Optimus, Bumblebee, Ironhide, Ratchet, Sideswipe, and the twins who Bay said weren't coming back are coming back. New characters for autobots include a robot named Silverbolt a red ferrari, a purple car, a blue car, and an autobot scientist. Also there introducing a new team of robots that will work with the autobots called the Wreckers, three nascars. There will also be two robot assasins ( decepticons ). And as for any returning unknown but i can tell you this they have comics that take place in between the movies and there coming out with a comic series called Transformers: Nefari or something like that which takes place after the second film and somehow Ravage the dog like decepticon who was killed by Bumblebee somehow comes back to life and Alice that robot chick from college somehow comes back and was captured by sideswipe after stealing an RV and was taking to NEST for tests. Oh and one more thing. The film is supposed to start of during the days where John F. Kennedy was president and something with a decepticon on the moon happens. But the film supposely says that the decepticons had something to do with the cold war and World War II. Hoped this helps
- Q: I just heard from a guy who works with either the electric company or construction that the transformer behind sams club(where i work) caught on fire and its going to be a long term job. The power is out for them, walmart, kohls, and like 10 other large businesses nearby. Anyone have any idea what kinda time frame that would be to fix that? I wanna know if I'm going to be out of a job for a few days or not. Its too late to call and ask. So how long does a transformer take to repair/replace?
- If the transformer belongs to the utility company, then they usually have it replaced within 24 hours. If it is privately owned then it could take a week or more.
- Q: Transformer winding maximum temperature at?
- National standard (oil-immersed transformer) the top of the oil temperature is generally adjusted at 85 ℃, if more than 85 ℃, to analyze the reasons: 1, if it is because the room temperature is too high, heavy load and other slowly rising, you can continue to run more than 85 ℃, but The maximum temperature can not exceed 95 ℃ (when the transformer core core or winding is 105 ℃, will seriously damage the insulation, shorten the life or burn the transformer); 2, the transformer running at 85 ℃, the transformer oil temperature and room temperature difference can not exceed 55 ℃, if it is over, may be a serious overload, the voltage is too low, the current is too large, internal failure, etc., continue to run will seriously damage the insulation, shorten the life or burn the transformer.
- Q: LED non-isolated drive transformer (two windings) calculation method
- T cycle, f frequency D minimum duty cycle Vout output voltage Vin input voltage Ton magnetizing time
- Q: What is the difference between AC transformers and DC transformers?
- DC can not be used transformer transformer, (available switch circuit DC-DC conversion.) Only AC only transformer with transformer.
- Q: assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain
- In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.
- Q: 1- the properties of electrical transformers . #92;2-their uses . #92;3-their applications.
- 1 - Transformers step-up or step-down voltage in a closed electrical circuit. 2 - Power companies send electricity at over 500,000 volts through power lines. They use transformers to convert their power to this level and a second set which lower the voltage for home/office use. 3 - Allowing you to use electricity at different voltage levels for different applications.
- Q: A 630 kVA, 11kV/400V transformer. Rp, Xp, Rs, Xs, Rc, and Xm are given. How to find secondary and primary? Do I need to calculate the total impedance referred to the primary and secondary or can I calculate currents without it?
- Given its capacity this is almost bound to be a three phase transformer. You need to know the connection of the primary and secondary windings (Y or Δ) to determine the windings' currents. You can basically calculate the rated currents from the kVA rating and voltage without using the impedances, eg. Ip primary rated current 630/(11 x 3 x √3) which assumes a 3 phase transformer with a Y-connected primary. Edit: If the capacity value is totally unreliable then there's no way you can find the rated current with only the other values you give. You need the load impedance as well.! This applies whether it's a single or a three phase unit I'm afraid. Why do you bother me with useless data? If you do this kind of thing to your employer in later life you'll rightfully get scalded!! On top of that you don't even initially say please or later apologise for such a gaffe.
