Q:I have an old xray machine with a large step down transformer.Its not shorted but the paper insulation looks to dry. Is there a special oil for this? Thanks.: The manufacture of the transformer would have provided environmental protection. There are many ways to provide protection but most involve large pressure cookers that are designed to apply high pressure to the transformer will drying. Various waxes and epoxies are used and the pressure makes certain the sealer is driven into the transformers windings, then allowed to set. As far as I know, except for certain types of large transformers where the entire transformer is installed in a bath, oil is not used.

Q:I purchased a doorbell in Europe, it has a transformer that goes from 220V to 14.8V, will the transformer work on 110, or do I have to replace the transformer?: If the mains side (primary) has a switch or 4 connections then it can probably be configured to work, as some transformers have dual 110v windings and are connected in series for 220v and parallel for 110v. Otherwise its not up to it.

Q:I have a 240 to 12 volt electronic transformer for each 50w halogen bulb. Trying to track down a fault, I tested the transformer with my multimeter - it showed 240v input but showed zero v output so I concluded that the transformer was faulty BUT when I plugged in a bulb it lit up normally. Can anyone explain ??: Different kind of voltage. Did you switch your multimeter to read DC voltage? Most lighting ballasts are ac output (like fluorescent or metal halide). In the case of mr16 50w light bulbs typically power is 12v dc output from either an electronic or magnetic transformer. Magnetic is heavy iron with copper wound like a typical door bell transformer. Electronic is smaller and lighter using circuit boards to convert the voltage. In both cases it will be DC. Something else to consider is worn contacts where the bulb connects. And m16 bulbs don't last very long. Oil from your hands will shorten their lifespan even more. Also poor heat dissipation through the fixture. I've worked with a lot of the types of fixture you're speaking of. (usually 4 recessed cans but also pendants and track fixtures)

Q:does anyone know how big the transformers are in the movie or have an online reference?: lol to tell you the truth, I've been to the L.A. Transformer's movie premiere, I've seen a life-size BumbleBee model with my own eyes and it's about 2 stories tall (I also took some pictures but not clear though)? Optimus Prime, about 3~4stories tall? And if you use search engines, you might find some funny insider stuffs from fansites, have fun!

Q:about transformers: Your logic is valid but a careful look will tell what is happening. This strange behaviour is not that uncommon, it has analogy in other areas also. For example when you push a large stone, it is pushing you back (famous third law), then how does it move at all, if it cancels the supply force? On the other hand when you push a strong wall, it reacts with equal and opposite reaction. The thing is if the wall did not exert this reaction it would have allowed itself to be pushed back without any resistance!! These action / reaction like, supply voltage and induced emf (other examples are terminal volt of a d c motor and back emf, generator output and its reaction on prime mover etc etc) are all must be conceptually understood. I can dare say that they do not exist as such! They are merely way of understanding the concepts. When you supply ac volt to a coil (transformer without secondary load is just a coil) because of energy transformations taking place we see that the coil offers resistance much different from pure resistance, which is called impedance. But the same can be viewed as reduction of available voltage due to induced emf. I repeat this is a conceptual understanding of the phenomenon.

Q:Power industry, Taiwan change, Taiwan, transformers in the concept of what is the difference? Also, what does the measurement point mean? First into this line, hope you brothers help.: Metering points are generally placed on the two sides of the equipment for property rights demarcation point. Some "real production boundaries" are not suitable for loading tables, the measurement points can be located in the substation, if the measurement point and production to the demarcation point is different, the asset owner should bear the loss of their own property equipment. For the substation of the various routes, the measurement point is located in the various routes on the outlet. Transformer two transformers run parallel to the situation is very common. Parallel operation can make the power quality better, and better play the potential of equipment and so on.

Q:!!! I took a cardboard cylinder from a used firework, dug out all the crap, wrapped 160 turns of tinned copper wire on the outside tight and evenly so it is a beautiful solenoid, held it in place with 2 rubber bands. That was the secondary. Then I wrapped an insulated steel wire around a screwdriver shaft 10 times, stretched it out a little inserted a chopstick into this primary and inserted the chopstick into the firework. I then held it all in place with tissue paper and tape and wired the primary up to a pulsed DC circuit which was made of 3.0 volts wired to a steel file which I rubbed the electrode across. The secondary was wired to a current detector but I got no signal! Why is there zero inductance in my transformer and why is there no current at all? It can't even light up a small lightbulb!!: Capital and minuscule letters are differentiated in the Roman, Greek, Cyrillic, Armenian and Coptic alphabets. Most writing systems (such as those used in Georgian, Glagolitic, Arabic, Hebrew, and Devanagari) make no distinction between capital and lowercase letters, a system called unicase. Indeed, even European languages did not make this distinction before about 1300; both majuscule and minuscule letters existed, but a given text would use either one or the other. In alphabets with a case distinction, capitals are used for capitalization, acronyms, and emphasis (in some languages).Capitalization is the writing of a word with its first letter in uppercase and the remaining letters in lowercase. Capitalization rules vary by language and are often quite complex, but in most modern languages that have capitalization, the first word of every sentence is capitalized, as are all proper nouns. Some languages, such as German, capitalize the first letter of all nouns; this was previously common in English as well. (See the article on capitalization for a detailed list of norms).

Q:A single phase transformer operates from a 230V supply. The primary and secondary resistances are 0.03 Ω and 1.12Ω respectively while the corresponding leakage reactances are 0.1Ω and 6.4Ω; the magnetising branch can be neglected. The secondary winding has four times as many turns as the primary. Calculate :i) The equivalent impedance referred to the primary circuitii) The secondary terminal voltage when the load has a resistance of 200Ω and an inductive reactance of 100Ω.iii) The secondary terminal voltage when the load has a resistance of 200Ω and a capacitive reactance of 100Ω.Can someone show me how to tackle this question please?: i) the secondary transformer impedance is 1.12 + j6.4Ω. Since Ns/Np 4, this impedance reflected to the input is (1.12 +j6.4Ω)/(Np/Ns)? 007 + j0.4Ω ii) Reflect the primary transformer voltage and impedance to the secondary side. 230(Ns/Np) (1.12Ω + j6.4Ω + (Ns/Np)?(0.03Ω + j0.1Ω ) +200Ω + j100Ω )I 920 (1.6 +200 + j8 +j100)I (201.6 + j108)I |Z| 228.7Ω √(201.6? + 108?) at angle of inverse tan (108/201.6) 28.18° I 4.02 amps at -28.18° 3.54 - j1.90 amps The terminal voltage is 920 - (1.6Ω +j8Ω)(3.54 - j1.90 amps) iii) solve 920 (1.6Ω +200Ω + j8Ω - j100Ω)I (201.6Ω - j92Ω)I The terminal voltage is 920 - (1.6Ω + j8Ω)I

Q:The core part of the transformer is composed of sub-and sub-components, which are generally divided into two transformers. Urgent, quick answer What is the core part of the "what" and "what" sub-composition ah? The "What" son, this "what" is to fill you ah.: The core part of the transformer is composed of (primary coil) and (secondary coil), generally divided into two types of step-up transformer and step-down transformer. (In fact, there is not a step up and not buck the isolation transformer) Did not hear the transformer "what son".

Q:I fried a transformer in my lathe. I went to the electrical supply near my house and the got me a new transformer and said it will work. The old transformer is 3 times bigger. they are both 100VA. the voltage on the original is 230v in and 100v out. It powers the on/off switches for the forward/ reverse micro switches. from the micro switch it powers the magnetic puill in for the contactors. The contactor say 100V.will using a 110v transformer cause and problems or issues?Should I return the one I purchased and order a 100V ?I have work piled up and waiting and really need this lathe operational ASAP.Thank You in advance for any information.Earle: It should be fine. A 10 increase in voltage will create about a 10 % increase in current through your contactor coils and control switches. This is generally well within the safe limits of electrical design.
