- Q: if the transformer converts 240v ac to 8V ac, ratio 30:1 then it should step up the voltage by the same ratio, i.e, 15V ac to 450v ac.but it's not the case !!
- Ok firstly,you're going to need ALOT more than 80v if you plan to power a transformer. When in its transport form, be it a plane, car, lorry etc you can run it on ordinary diesel fuel, however in Robot form, In order to make it walk, your transformer would need far more power than a diesel engine could provide. Take Optimus Prime for example, the weight ratio of Prime, which would likely exceed 75 to 80 lbs per inch might be impossible to provide enough power to move your transformer on two legs. If you are well educated in hydraulic engineering, hydraulic power might allow your transformer to walk, but the hydraulic system itself would create a different lot of problems.The hydraulic pipes, along with your transformers fuel lines and electrical wiring, would have to remain undamaged or even untouched during transformation, and a secondary power source must be used to power the hydraulic pumps. In conclusion, If you're planning to power 35 to 40 tons of pure machine, good luck. Hope this helped.
- Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?
- primary coil keeps on running at full power incorrect. wrong. The secondary has a load, and that load draws current, which may be anywhere from zero up to the maximum load rating of the transformer, say 10 amps. Depending on the turns ratio (say it is 10:1), that amount of current is supplied by the primary, multiplied by or divided by the turns ratio. In our example, this would be 1/10 th the secondary. So if the secondary drew 10 amps, the primary would draw 1 amp from the wall socket. If the secondary drew 1 amp, the primary would draw 0.1 amp. And 0 amps would cause the primary to draw 0 amps from the wall socket (for an ideal transformer. Real world, there is a small current being drawn, how small depends on how good a transfomer it is) edit, for your additional details. I determined that it keeps on running at full blast based on the idea that it's a separate circuit. wrong Since it is always creating magnetic field (which it must, since it's a coil), and creating even when no ones taps on it, it must run at full blast at all times. wrong, with no load, the magnetic field is much weaker. Unless there's a way the primary circuit automatically knows nobody is tapping on it, it must be constantly making magnetic field at full blast. wrong.
- Q: I am powering a lighting system with a mixture of SCR dimmers and HID lamps. I am pulling approx 285 amps/leg at 120/208V through a 150 kVA transformer. The 120/208V service coming from that transformer is indicated to be 400A/leg, but it seems to get pretty hot at 285A.
- Three phase transformers are given a power rating which is the sum of all three powers on each phase. So 285 amps on each phase at 120 line to neutral (assuming this is how youve them connected) is about 35kva, so about 100kva all up. What is actually on the name plate of the transformer? How hot is 'pretty hot'? Is it running as it was desinged (oil, dry, forced air cooling etc). Also how are your lamps/dimmers wired? The other answer is correct, the dimmers will produce alot of harmonics. The meter your are using to read the current is most likely designed to read a 60hz sine wave, any other stuff there will cause a wrong reading (they usually measure the average value, then apply a correction factor to obtain the rms value. But this factor depends on the wave shape, if its not a sine wave it will be wrong). See if you can obtain a meter that will measure the true RMS current. Transformers of that size are usually heavily over engineered, it should be fine as long as the tempertature doesnt continue to increase, ie to the point where the case is too hot to touch. As the other answer said it is probably rated for continuous operation at about 75 degrees. Id not worry too much as long as the temperature doesnt continue increasing.
- Q: coz in a step up transformer the voltage is increased and the and the current is decreased and vice-versa . and the ohm's law states that voltage is directly propotional to the current .now in a transformer we r making the current inversly propotional to the voltage
- A transformer does not make the current inversely proportional to the voltage; the currents in the two coils are inversely proportional to the turns ratio Q. If the secondary (output) coil drives a resistance, the current depends on Ohm's law; Is Vs/R. The resistance equals the ratio Vs/Is. But the ratio V/I in the primary (Vp/Ip) is multiplied by Q^2; that is, V is proportional to Q and I is proportional to 1/Q. So the power source driving the primary sees a load resistance Q^2R. The power, or product of V*I, is the same in the primary and secondary. But no matter what you do with the input voltage, the currents in both windings change proportionally to voltage. You can think of a transformer as similar to a lever, where V and I correspond to F and d (distance), F/d correwponds to R, and Q corresponds to the applied-work and output-work lever lengths. Work Fd is constant on both ends of the lever, and F/d has a Q^2 relationship between the two lengths of the lever.
- Q: I live in US and I will move to my home country where 240V is supplied in the power sockets.I'm planning to ship my computer, LCD TV, speakers, game console, etc. and buy a power transformer. However, I'm afraid the power loss in the transformer will raise my electric bill so in the long run, it's not worth it to ship my electrical appliances.So how much is the typical power loss in a 120/240V step up transformer? The range of efficiency would help.
- In any transformer when you magnetize it your using electricity. Even if you have no load on the secondary.its just not very much.going from 240 Euro to 120 USA may not be a problem . But beware the 50HZ power supply .The actual loss for most small transformers in per cent is 12%that's 12% on the secondary. say your using 100 watts and have a lose of 12% at 120 volts the secondary amperage for this example would be [100w /120v] x 1.12.93amp the extra .12 amp is created to overcome the loss. Most computers have a switch for selection of hz and volts and a lot of tv's etc do to,,take a look before you throw em outHave a good one from the E
- Q: I need to find out.I am a huge Transformers fan.
- i liked the first one. the second was a huge disappointment for me. with an old man transformer and two corny ones who talked black but came off as just plain retarded. the action was good, megan fox was hot, and shia lebeouf did good. but transformers 2 was a movie where it seemed they tried way too hard.
- Q: I took apart a wall transformer before and soldered a single AA battery to the outputs and touched the what was before inputs and it gave me a shock. This is because it stepped up the power to something like 113v. Could I instead of a AA battery use 110 from the wall. Would it do the same thing. Or would it just overheat the transformer. And what would the amps be. I’m trying to make like a 20amp welder for just screwing around with.
- You will blow fuses DO NOT TAMPER WITH THINGS YOU DON'T UNDERSTAND a primary winding has enough turns to reduce magnetizing current to a few mA you put lots of volts on a few turns (secondary) and the core will overheat, that's if the primary does flash over (a battery momentarily connected will cause a corresponding stepped up voltage pulse on the primary) A permanent connection will flatten the battery (almost a dead short)
- Q: hey all , i have 2 phase welding machine fed from 30A 3 phase circuit breaker , at high loads above 40A CB cut off the Supply . the problem is i cant change the CB size bcoz it Contrary to legislation in the country . Can i used scott t transformer to balance the load at the main 3 phase ?
- you're starting to be to be meant a single section welding device. This unit includes 2 supply lines. those lines may be linked to any 2 lines of a three-phse ability supply device.only connect one line to L1 and the different line to L2, only examine the line to line voltage of the flexibility supply. It must be the comparable by way of fact the welding device score, say, 380VOLTS, 50 Hz.
- Q: If on the secondary coil we tapped the center to ground, why is it that the top to middle is opposite in polarity when compared to the middle to bottom of the inductor? Also does this only happen if their is a change in current and not constant current going through the transformer?
- the first question think of it as a single coil, 24 V transformer when you measure from bottom wire to the top wire you will measure 24V if you measure from bottom to center it will be 12 V the same from the center to the top maybe it is easier to understand if it were 2 batteries in series images.google.ca/images?hlfrsou at the moment in time that the top is +12, the bottom is -12 therefore giving the 24V this is always like that regardless of the nature of the load Anita
- Q: im building a step up transformer and im wondering if a 10:130 turn ratio would give me the same results a 100:1300 turn ratio. my specific questions are:1) Would i get the same power boost?2) If not, would it be similar or close to it?3) If not, why not?
- It will give you the same open-circuit voltage ratio. Winding more turns on the cores will increase your inductances on both sides. That reduces the open-circuit current on the driving side. More wire resistance will result in more resistive loss when operating with a load.
