Q: 1.Is there going to be a Season 4?2.If there isn't,then is there going to be a new Transformers series?: Transformers animated ended last Saturday with Endgame part II. It was ended because of the movie coming out and Hasbro wanted to focus on movie merchandise. There's been some talk of maybe it starting up again after the movie or even a new cartoon.

Q: I know that before the 2007 release of transformers and this years sequel there were various animated tv series and comics. I just want to know what the live action movies are actually based on. Like are the movies just real life portrayls of the the animated story line? Or are they original plots just based on the ideas of autobots, decpticons and there home cybertron?If the plots for the movies are based off the comics of series (like the x men movies) what could be the possible plot for the 3rd installment of the film franchise?: The Transformers film was based on the first film, The Transformers: The Movie (1986) which was based on the animated series. Transformers are alien robots of a popular Hasbro toy line and its spin-offs. The Transformers began with the 1970s Japanese toy lines Microman and Diaclone. The former utilized varying humanoid-type figures while the latter presented robots able to transform into everyday vehicles, electronic items or weapons. Hasbro, fresh from the success of the G.I. Joe: A Real American Hero toyline, which utilised the Microman technology to great success, bought the Diaclone toys, and partnered with Takara. Jim Shooter and Dennis O'Neil were hired by Hasbro to create the backstory, the latter of whom christened Optimus Prime. Afterwards, Bob Budiansky created most of the Transformers characters, giving names and personalities to many unnamed Diaclone figures. The primary concept of G1 is that the heroic Optimus Prime, the villainous Megatron, and their finest soldiers crash land on pre-historic Earth in the Ark and the Nemesis before awakening in 1984.

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: What are the technical parameters of the transformer?: I, temperature rise and cooling: transformer winding or the upper oil temperature and the temperature difference between the ambient temperature of the transformer, known as the winding or the upper oil temperature rise. Oil-immersed transformer winding temperature rise limit of 65K, oil surface temperature rise 55K. There are a variety of cooling methods: oil from the cold, forced air-cooled, water-cooled, tube, chip and so on. J, Insulation level: Insulation class standard. Insulation level of the method for the following example: high voltage rated voltage of 35kV level, low voltage rated voltage of 10kV level transformer insulation level expressed as LI200AC85 / LI75AC35, which LI200 said the transformer high voltage lightning impulse withstand voltage of 200kV, power frequency withstand voltage For the 85kV, low voltage lightning impulse withstand voltage of 75kV, power frequency withstand voltage of 35kV. Oaks High Technology Co., Ltd. The current oil-immersed transformer product insulation level LI75AC35, said the transformer high voltage lightning impulse withstand voltage of 75kV, power frequency Withstand voltage of 35kV, because the low pressure is 400V, can not be considered. K, the connection group label: According to the transformer one. Secondary winding phase relationship, the transformer winding connected into a variety of different combinations, known as the winding group. In order to distinguish between different groups, often using the clock representation, that is, the high voltage side of the voltage phase of the clock as a long needle, fixed on 12, low voltage side of the phase voltage as the clock short needle, (A) is a (triangular) joint, and the secondary winding is a (star) junction with a center point, and the group number is (11).

Q: Transformer if the boost and buck current will change? According to the power of the same should be high voltage side of the current point is also the opposite? Boost and buck can be specified?: According to the formula P = √3IVcosφ ,, in the case of P unchanged, V increases, I on the drop, V down, I on the rise in the case of the transformer load is constant, increase the voltage and current drop, reduce the voltage and current rise; The

Q: Guys can you tell me that how can I calculate transformer winding?Example:- I need (12volts, 4Amps, 50Hz on Secondary's side of transformer and give 230volts 50Hz on Primary's side of transformer) how I calculate the wire's number of turns? In this case I can give different values of current like 1Amp, 2Amps, 3Amps etc on Primary's side of transformer. But I need constant 12volts, 4Amps, 50Hz on secondary. So how can I calculate.Please give an answer with an example basis on (0-12) transformer.: As others said, only worry about the voltage ratio. That determines the turns ratio. Current doesn't enter in to this equation yet. The minimum number of turns on the primary is dictated by two things, the saturation flux density and magnetizing inductance. Flux density is proportional to the applied voltage, inversely proportional to frequency and effective area of the core. You'll need to know the saturation limits for the core you are using. You also need to have a minimum numbers of turns to minimize the no-load current which relates to magnetizing inductance. My rule of thumb is the inductive reactance must be 5x the maximum expected load resistance, however, for a AC mains transformer, this is often a hard number to quantify since the load can be near zero. Next is wire size. You will need to consider proximity effect losses as well as DC losses. You'll find that there is an optimum wire size for the windings, but for a 50Hz transformer, you'll probably use a wire diameter smaller than optimal for a low power transformer. I suggest reading about this in Ferrites for Inductors and Transformers by Snelling and Giles. You may need to make compromises to meet your needs. This is where the current supplied by the transformer comes in to play, maximum heat loss expected. While making your own transformer is educational, for power mains transformers, you are better off buying one or scrapping it from an old piece of equipment.

Q: I am re-winding transformers, and I was wondering if braided copper wire can be used for the secondary winding. I will be using large gauge wire (4-8 ga.) and I just need to know if the performance will be terrible if I do use it.: It will be fine. The diameter will be a little larger so you can't wind as many turns. also, I never saw varnished stranded wire, so you would have to do your own varnishing. #4? 100 amps?

Q: What is an isolated ring transformer?: Isolated ring-type transformer is mainly focused on its insulation performance, between the primary and secondary must have a double insulation, so that the isolation of its own high efficiency, effective protection of equipment safety.

Q: 1- the properties of electrical transformers . #92;2-their uses . #92;3-their applications.: Through magnetic induction, a transformer transfers electrical energy from one circuit to another. I think it is used to step up/down the number of volts. It also allows alternating current to transmit electrical power over long distances.

Q: actually I've many questions :) I've opened many mobile chargers and I didn't found the usual (bulky) transformer . I found only a small transformer and I think it called smps transformer.1- I can't understand how bulky transformers can be replaced by small ones! what is the idea ?2- are smps transformers connected directly to 220 volt like the bulky transformers ? if no, what is the design of the circuit that makes small transformers are able to be connected to 220 volt ?3- do smps transformers make a voltage drop like the bulky transformers ? or they have another job ?4- some smps transformers have 4 pins and the other have 5 or 6 pins, I know it should have 2 pins for input and 2 pins for output, why some of therm have more than 4 pins ?Thanks in advance, I hope i'm not bothering you because of my many questions :): The higher the switching frequency, the smaller you can make the transformer without the metal core saturating.
