Q: How many transformers are used in a hundred households?: Depending on the specific use of electrical power. First select the rated voltage of the transformer. The voltage on the high voltage side is equal to the voltage of the connected grid. The voltage on the low voltage side is 10% or 5% higher than the voltage of the low voltage side (depending on the voltage level of the transformer and the magnitude of the impedance voltage). Calculate the size of the load carried by the transformer (requires the maximum statistical load, the conversion of the operating load kW value into apparent power kVA). If two transformers are used, the capacity of each transformer can be selected according to 70% of the maximum integrated load. The transformer should be considered for the total load and leave the appropriate margin. Other brand name parameters can be combined with the appropriate consideration of the transformer product. For example: select 35 / 10kV transformer. Assuming a maximum load of 3500kW, power factor of 0.8, choose two transformers, capacity S = 0.7 × 3500 / 0.8 = 3062kVA, 3150kVA transformer can choose, the voltage ratio of 35kV / 10.5kV. Select the model from the catalog.

Q: I work in the power plant, today there is a task is to charge the lighting transformer, I would like to ask the next. What does it mean to charge the transformer? What does this charge mean? What is the use of? Thank you: Is not wrong. Transformer itself is not stored function, that is, there is also a very short cut. You say is not to the transformer power ah

Q: i am planing to get the eee pad transformer, can it download anything from the internet browser just like a computer does or it can only download apps from its own app store like ipad does. should i get the transformer or ipad 2 ?: i flow to attempt to make this record as clean as a danger with out growing to be use of too a lot words: reward of the iPad 2: - Intuitively simplistic (too simplistic to a pair peoples style) - Polished - eighty grams lighter (uncertain no remember if honestly anybody notices that :P) - extra helpful app shop (and stable now graphically some extra desirable ideal video games) reward of the Asus transformer: - swifter (not in many circumstances a substantial vast difference) - Flash help - - TIP: *DISABLE* flash each and each time you don't like it on the asus transformer, reason it improves velocity a lot (apple desperate for the guy that he's not allowed to prepare flash, asus/android believes the guy can take care of a few accountability) - not in straight away forward words a intake (examining/gaming) gadget, yet _can_ be used for production besides - extra helpful battery (because of the dock) - extra desirable ideal show - fairly various customization (you would be waiting to as appropriate run laptop OS's on it :D, yet it fairly is in simple terms for nerds) *My suggestion: in case you may carry your breath for some extra desirable months i ought to suggestion you to watch for the Asus Transformer 2, in any distinctive case the iPad 2 and Asus Transformer a million are fairly matched, yet i think of the Asus Transformer ought to nonetheless have the side*

Q: Transformer total circuit breaker rated current 380v, rated current 1000a, the rated capacity and output power how to calculate, I did not learn more points: Kva is apparent power, KW is active power. inspecting power: S = 1.732UI = 1.732 × 0.38 × 100 ≈ 65.8 (Kva) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × cosφ

Q: I have a US Navy Plate and Filament Transformer Manufactured by Hudson American Corporation.This monster weighs 14.5lbs, and is in a sealed steel casing.There are 16 unlabeled terminals, and I'm working to identify those.It does however have the current and voltage labelings for the primary and secondaryPrimary : 110/115/120v AC (Since there are 16 taps, I'm guessing that these are separate primaries)Secondary 1:360-0-360 200MA DCSecondary 2: 6.6v 10A CTSecondary 3: 12.6V 3ASecondary 4: 5.25V 3AI'm set on using a solid state rectifier circuit so i don't need the 5.25V Line, or the 12.6V line.Could I somehow do something to get extra current on the B+ line (S1 windings) with these unused secondaries?I want 4x 6550/kt88, so the extra plate current would be great to have around.: You can probably draw a bit more from the 720 volt winding if you don't use some of the other windings. Also if you use SS rectifiers, you will get more DC voltage than normal, about 490-500 volts, so the extra drop you would get at higher current may be ok. Or you could use a choke input filter instead of a cap input to get about 350 volts, enough to operate KT88's, and get more current. Watch out for over heating. edit: Electrolytic caps would be a lot smaller than the ones you have. The two chokes in parallel could be used as a choke input filter. Exactly what voltage and current do you need?

Q: Transformer cooling method AN stands for what: The cooling mode of the transformer is determined by the cooling medium and the circulation mode. Dry-type transformer cooling method is divided into natural air cooling (AN) and forced air cooling (AF); oil-immersed transformers commonly used cooling methods are generally divided into three types: oil-immersed self-cooling, oil-immersed air-cooled, forced oil circulation.

Q: Do stores that sells computers, printers, etc. also sell transformers: Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.

Q: Do you think if I asked this. which I am maybe people will pick Transformers because more Americans watch Trans instead of Gundam but if people watched both, would they still pick Transformers?: What, in a battle or as in an anime? If it's anime, I pick Gundam. If it's a battle. Well Transformers got someone called Unicorn who's the size of a Planet. So you can imagine how powerful he is.

Q: come on.the battle scenes and all the transformers were totally awesomebut.all the small jokes that sam and his parents and other various characters madejust killed itlike they were actually trying to add a comic element to it.and what is with the transformers cussing? it doesnt feel righttransformers dont cuss.lol: I haven't seen it, but I heard it was worse than the first one.

Q: I need help figuring out this transformer question. I have no idea how to go about it and any information or help will be useful.A 100-kVA, 60-Hz, 7200-480 V, single-phase transformer has the following parameters expressed in OHMS:Rhs3.06 Rls0.014Xhs6.05 Xls0.027Xm,hs17,809 Rfe,hs71400The transformer is supplying a load that draws rated current at 480V and 75 percent power-factor lagging. Sketch the appropriate equivalent circuit and determine:a) The equivalent resistance and equivalent reactance referred to the high side.b) The input impedance of the combined transformer and loadc) The load component of high-side current;d) The input voltage to the transformere) the exciting current and its componentsf) the input impedance at no load: A 100-kVA, 60-Hz, 7200-480 V, single-phase transformer has the following parameters expressed in OHMS: Rhs3.06 Rls0.014 Xhs6.05 Xls0.027 Xm,hs17,809 Rfe,hs71400 Primary winding is 15*N turns r 3.06 ohms in series with The primary leakage reactance which is L 16mhy(6.05 ohm @60Hz) in series with the magnetizing indctance Xm 17809 ohms 47.24hy which completes the primary series string the core loss is modelled as a 71.4k ohm resistor across the magnetizing inductance the secondary winding is 1*N turns R 0.014 ohms in series with the secondary leakage reactance is L 71.3UHy(0.027ohm@60Hz) the load draws 208.33A (100,000VA/480V) Z 2.304 ohms @ 48.6 deg 2.30448.6 1.786 ohms in series with +J 1.524 ohms(4.042mHy) (75% pf comes from voltage drop is seen from 2.304 ohms but only 75%(1.786 ohms) is resistive transfer from secondary to primary is done by multiplying impedances by 15^2 225 you should be able to do it from here.
