Q: An AC generator, originally designed to provide a peak output voltage of ± 155 V at a frequency of 60 Hz, is required to provide a peak output of ± 340 V at 50 Hz. If the generator is connected to a transformer with 200 loops in its primary coil, how many loops should there be in the secondary coil in order to provide the required output?Using the formula Np/VpNs/Vs I get 439 coils, but this is too easy for a 6 mark question and doesn't include the change of frequency. I have no idea what to do and need some help :(: Your answer is correct. The frequency has no effect on the turns ratio. The frequency does effect the required primary inductance, however. More turns with 50Hz, about 20% more for same magnetizing current as with 60Hz. I am assuming your generator can change frequency.

Q: A 2200/220V, single phase transformer has the following resistance and leakage reactance referred to primary: R5.6 ohms, X22 ohms1. calculate V2, I2 and cos(2) when the primary is supplied with 2200V, 9A at a lagging power factor of 0.8. Neglect Io.: I2 I1[V1/V2] 9[2200/V2] I29[2200/20] 9[10] I2 90 amperes. V2 220 volts

Q: I'm getting a transformers game and idk which one to get. Should I get Transfermors: WFC (War for cybertron) or Transfermors Dark of the moon? Which one is better?: Out of all the transformers.WAR of CYB was the best!! Because it had no restriction to the movie But I think you should get The New one!! Looks Awesome though but will be expensive.

Q: Step-up transformer, low-voltage winding put the middle, that is, low-high; Step-down transformer, medium voltage winding in the middle, that is, low high. For the step-up transformer, the input is low and the output is high or medium; the low-lying intermediate makes it possible to minimize the distance in the low-high, low-, thereby reducing the distance traveled by the magnetic energy, Loss, reduced low - high, low - in the leakage resistance, thereby reducing the low - high, low - between the short - circuit voltage percentage, thereby reducing the reactance, thereby improving the energy conversion efficiency of the transformer. For buck transformer, the input is high, the output is low or medium, similar to the step-up transformer, the optimal arrangement should be low, high, medium. However, due to insulation safety problems, the high voltage side must be placed at the outermost end. So the arrangement of sub-optimal way to low, medium and high.: 2, from the manufacturing cost considerations, the transformer core is grounded. Low voltage coil inside, the coil on the core of the insulation distance can be smaller. So that the sum of the main insulation dimensions of the three coils will be smaller. The weight of the entire transformer, the volume is relatively lower than the - low - high arrangement to be smaller.

Q: I'm 13 and I love the Transformers movie, TF Animated and TF Armadaactually, those are the only ones I HAVE seen so farI'm just wondering where to start with attempting to watch them all? And in what order? Or, doesn't it matter? I suppose it does with G1 and 2Where on the internet can I watch them? Any recommendations?Please answer! I really want to have seen every one!: not okorder

Q: Transformer Uk = 4.5% What does it mean?: Transformer short-circuit impedance, that is, his own impedance. The impedance is large, the transformer needs to resist the short circuit current multiplier is small, relatively speaking, anti-short circuit capability, but the transformer's external characteristics (volt-ampere characteristics) soft (with the transformer output current increases, the output voltage - transformer Voltage drop is very powerful). On the contrary, short-circuit impedance is small, the transformer needs to resist the short-circuit current multiplier, requiring a strong anti-short circuit transformer capacity. Of course, the external characteristics of the transformer better. Another short-circuit impedance will also affect the transformer manufacturing costs. He is not the bigger the better, nor the smaller the better. To be considered, so there are strict rules in the national standard.

Q: From the following transformer, how would I calculate:a) the equivalent impedance on the low-voltage sideb) Converting the impedance found in (a) to it's per-unit quantities: a) the turns ratio of the transformer is 20 to1 so to refer an HV side impedance to the LV side you divide it by the square of the turns ratio which in this case is 400 which gives: 0.001+j0.00025 ohms. b) There's a certain amount of freedom in doing this for you may define the per-unit impedance base however you want. It is however rather usual to define it as VA / I^2. Here I 5000/2400 2.083 amps So base impedance HV side 5000/2.83? 624 ohms making the given impedance (0.4+j0.1)/624 p.u. This p.u. value should be the same on either side of the transformer. Nice to see you around again but do I notice you haven't improved at saying please when you want someone to do something for you for nothing. If you can't learn that there's not much use in learning all these technical skills. You're going to remain a clumsy oaf!

Q: Hello, I'm new to electronics and I would like to know how is the current affected by a step-up or step down transformer. EX: Lets say you have a pure AC wave (60Hz , 25vac, 5A) hooked up to a 1:4 power transformer with a current rating of 10A, What will the voltage and current be and why? Thank you!: ok, so if you use the equation Fma you can isolate the force on the circuit by the power transformer. !st) F60*2pi3456 2nd) you plug it into the charge formula and get 32.086C, which is your answer.

Q: I am very dissapointed because i lovvvve transformers but how can the movie go on without her? I know i know. the show must go on. but cmon. i hope they pull it off., does anybody know why megan fox isn't going to be in it.: Cus she said in interviews how much she hates the director and the transformer movies.

Q: Transformer tap adjustment there are several ways? What are the advantages and disadvantages?: There are two ways to adjust the tap in the transformer. 1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.
