Q:What are the ways of protecting the transformer?: Transformer protection is commonly used to protect the internal fault of the main protection of gas and differential. Backup protection is quick and overcurrent. There are semi-insulating structure of the neutral point over-voltage protection (arrester), oil temperature alarm.

Q:Find the transformer ratio of a transformer having 350 turns on the secondary winding and 7000 turns on the primary. What RMS voltage must be applied to the primary of the transformer to develop an open-circuit secondary voltage of 63 V? if a load of 100 ohms is connected to the secondary winding what is the primary current, ignoring resistive and reactive losses in the transformer?: Same results as Electronbut in a different way. 7000 primary turns divided by 350 secondary turns, 20:1 ratio 63 volts on secondary times ratio of 20 1260 volts on primary. 63 volts divided by 100 ohms 0.63 amps on secondary. 0.63 amps on secondary divided by ratio of 20 .0315 amps on primary.

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.: It is only about 5 to 10 per cent power loss and the range of efficiency is 90 to 95 per cent.

Q:All the specifications work (ie. Hz, Watts, etc). But I wanted to know if it would make a difference if I used a capacitor voltage transformer as opposed to a different type. Thanks.: You seem to be asking about a ferroresonant transformer. You can use this type of transformer with electronics. There is an advantage to this type of transformer, but there are 2 shortcomings with them. A ferroresonant transformer does a better job of filtering noise than a standard transformer. Unfortunately, they are inefficient, wasting more energy than a standard transformer and they also create a lot of heat. If you use this type of transformer make sure it's well ventilated. The web site below has a very good article on transformers. The ferroresonant transformer article is just over half way down the page.

Q:What are the malfunctions and abnormal operation of the transformer? What is the difference between them and the line?: working principle: Transformer is the use of electromagnetic induction principle made of static appliances. When the transformer's original coil connected to the AC power supply, the core will produce alternating magnetic flux, alternating magnetic flux with φ said. The original, the secondary coil φ is the same, φ is also a simple harmonic function, the table for the φ = φmsinωt. By Faraday's law of electromagnetic induction, we can see that the induced electromotive force in the original and secondary coils is e1 = -N1dφ / dt, e2 = -N2dφ / dt. Where N1, N2 is the original, the number of turns of the secondary coil. U1 = j1n1, U2 = E2 = -jN2ωΦ, and the complex value is U1 = -I1 = jN1ωΦ, U2 = E2 = -jN2ωΦ, and the complex value is U1 = Let k = N1 / N2, said the variable ratio of the transformer. U1 / U2 = -N1 / N2 = -k, that is, the ratio of the original value of the transformer and the secondary coil voltage, is equal to its turns ratio and the difference between the original and the secondary coil voltage is π. And then come to: U1 / U2 = N1 / N2 In the case of no-load current, I1 / I2 = -N2 / N1, that is, the original and secondary coil current RMS value is inversely proportional to the number of turns, and the phase difference π. And then available I1 / I2 = N2 / N1 Ideal transformer original, vice coil power equal P1 = P2. Indicating that the ideal transformer itself without power loss. The actual transformer always has the loss, its efficiency is η = P2 / P1. Power transformers are highly efficient and up to 90%.

Q:I was wanting to buy my little brother a transformer toy, but not one of these cheap ones you buy today, but one you actual transform by yourself like when I was younger. So whats a good website where I can find some for him and me to play with, and I don't really want to spend to much on them, just enough.: The recent Transformers toyline that was tied in to the fourth movie does have a lot of (over)simplified Transformers (and some toys that don't even transform at all), BUT there are a few models that do have the complex transformations and articulation that traditional Transformers have. The easiest way to tell them apart is to look on the left side of the package. If it says Transformers Generations, then it's part of the Generations line and has a more complicated transformation. There are also Transformers Generations toys that are *not* part of the movie toyline, and those can also be distinguished by the packaging, which is not the white-and-red color scheme that the movie toys are in.

Q:Why is the transformer ah?: The AC power up and down operation. The So as to get the desired AC voltage

Q:A transformer rises the voltage in proportion of 1 to 10. If the power in the primary coil is 100 watts, we should expect a power of ____ watts in the secondary coil. a) 10b) 100c) 1,000: Transformers can step up voltage, but in doing so, they step 'down' the current. Ideally, the voltage will rise by the same proportion as the current will fall. And since power is PVI, the power will remain unchanged. So the answer is that the power in the secondary should be the same as the power in the primary, which is 100W.

Q:And what are the prospects for Transformers 3? I mean, should i just skip it?I forced myself to watch Transformers Twice. Didnt care for it much, either time. Barely, BARELY passable.: Hollywood EF'ed up the first one to make the second one

Q:Hello everyoneMy last question may be a little misleading and I couldn't respond to my own question so please forgive me when I rephrase it again.I have a 65w stepdown Input230/240 AC, Out: 115V AC. 65VA transformer and I wanted to know if I should be concerned about how much electricity the transformer draws just by the fact that it is plugged into the wall socket even when the hardware connected to it is not on.I don't need an exact figure. Just a layman's terms as what your typical transformer would draw. An absolute average idea of the average transformer.If I turn the transformer off, all my appliances will need to be reset when I turn the transformer back on again.So does an average one consume as much as a light bulb, or say something much more. like a computer etc.I just need a general idea. Thank you.: Transformers are generally 85% efficient. But for no load applications, series in an ammeter and you'll know the answer for a specific transformer.
