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 !!: It must be using different terminals for step up and step down.

Q: For my proposed new aluminium extrusion factory I ve the load of 250 kw heater and 670 HP of motors.Whats the kva rating of the transformer I should go for?Pls advice.: the kva rating of the transformer shows that the power factor of the load has been taken care of

Q: Halo4 - love the series, Halo 3 is my favorite, hated Reach. not sure if Halo 4 is more like halo3 or more like reach, will not buy if abilities are includedBlack Ops 2 - BLOPS was my favorite shooter, I will probably get this unless they lower the health to MW2/MW3 standards and they don't fix SMGsTransformers FOC - War for Cybertron was one of the best games I've ever played, but they made Dark of the Moon which was a really bad shooter, and I'm not sure if FOC will be bad as wellWhat would you suggest?: Definitely Halo 4. I'm kind of burnt out on CoD right now so I'd go with the new Transformers. I agree that War for Cybertron was fantastic. I had really low expectations of it when I rented it, but it turned out to be great! It's online multiplayer is really fun too.

Q: Why is the transformer coil insulation?: Insulation grade refers to the heat resistance of the insulation material used, divided into A, E, B, F, H grade. Allowable temperature rise is the limit of the temperature of the motor compared to the ambient temperature. Insulation temperature Class A Class E Class B Class F Class H Maximum allowable temperature (° C) 105 120 130 155 180 Winding temperature limit (K) 60 75 80 100 125 Performance reference temperature (° C) 80 95 100 120 145 Generators and other electrical equipment, the insulation material is the most weak link. Insulation material is particularly susceptible to high temperature and accelerated aging and damage. Different insulation materials have different heat resistance, the use of different insulation materials, electrical equipment, the ability to withstand high temperatures are different. So the general electrical equipment is specified in the maximum temperature of its work. According to the different insulation materials to withstand the high temperature of its ability to set the maximum allowable temperature of seven, according to the temperature size were: Y, A, E, B, F, H and C. Their allowable operating temperatures are: 90,105,120,130,155,180 and 180 ℃ above. Therefore, Class B insulation indicates that the insulation temperature of the generator used is 130 ° C. The user should ensure that the generator insulation does not exceed the temperature during operation of the generator to ensure proper operation of the generator. Insulation class for the B-class insulation material, mainly by the mica, asbestos, glass fiber by the organic glue or impregnated from. Commonly used B-class insulation materials are PVC glass fiber casing (yellow wax tube), 6520 composite paper, DMD insulation paper.

Q: HELP!! My boyfriend wants to see transformers and he told me I had to study up first lol! He wants me to know who all of the characters are because apparantly its from a comic or cartoon or something? I dunno but can anyone tell me anything about the TRANSFORMERS? I need to know characters and storyline etc. basically just anything u knowThanks lol.: I have already seen it. It has opened here is Australia several days ago. I am NOT a transformers fan and only knew some names because I knew kids who played with the dolls. I am NOT into the comic either. I can tell you now YOU DO NOT NEED to know any names. EVERYTHING you need to know is explained in the movie. But DO go and see it. It is an AWESOME movie. (It takes a lot in a movie to impress me - so that's a lot for me to say it is an awesome movie. Acting is not the best you'll ever see But over all - it's VERY VERY well done)

Q: I will vote for the best answer based on the use of simple vocabulary, I don't know much about transformers so try to keep it as understandable as possible. I know it's not a simple subject, thanks!: As you may know, transformers only work with varying current: AC, of whatever frequency. The varying magnetic field produced by one coil will induce a proportional current in the other coil. That's how they work. But the varying magnetic field will also induce currents in the metal core of the transformer. These are called eddy currents, are a waste of energy, and will result in excess heat. By using thin laminations for the core, and insulating the laminations from each other, transformer designers can minimize these eddy currents, and keep the transformer efficient. Don't forget my best answer.

Q: I really want to know what a transformer is, how it works, and why it works. I really want an answer that goes down the the atomic scale. I really want analogies. And please don't copy and paste stuff from websites. Please don't worry about getting second comment. The most scientific and well explained answer gets best answer.: I know this isn't what you asked for, but it gives a much better answer than I'm willing to type.

Q: Transformer if the boost and buck current will change? According to the power of the same should be high voltage side of the current point is also the opposite? Boost and buck can be specified?: According to the formula P = √3IVcosφ ,, in the case of P unchanged, V increases, I on the drop, V down, I on the rise in the case of the transformer load is constant, increase the voltage and current drop, reduce the voltage and current rise; The

Q: How to build inverters using ferrite core transformers, details assemblies.: Transformers are only tangentially related to inverters. You don't need a transformer to make an inverter. At its most basic level, an inverter is just a couple of switches. This kind of simple inverter will only output a square wave with amplitude equal to the dc voltage input. To get a sine wave, you would filter the output with a capacitor and an inductor, and to change the amplitude of the wave, you would use a transformer (or alternately place a boost/buck converter before the inverter). If you're going to use both an LC filter and a transformer, you can save on parts by using the magnetizing inductance of the transformer as the inductance of the LC. This is all well and good, but it takes a lot of math and analysis to actually size all of the components. If you're really serious about this, you should find a good textbook and read up on everything.

Q: I have a transformer scavenge from a VCD player, written 25W on VCD player, so that should be the transformer's VA rating ?I also measured the transformer, it has 2 secondary. It have 11.1VAC on 1st output winding and 13.1VAC on 2nd output winding.So if I were to use into DC (rectification) and calculate for other maths, should I use the value of 11.1VAC / 13.1VAC, or their average which is roughly 12VAC ?: A transformer rating is specified as a number of volt-amps (VA) where A is the RMS current. In cases where there are rectifiers, the RMS current may be far greater than the average current. This means that the power that can be delivered will be far less than the VA rating.
