Q:How can I use a range for the US at 220v in China at 220v? Step down transformers x 2?
No need, 240 volts work on both types. The frequency makes a difference in the motors. not so much for heating. Any electronics may be damaged by the difference because the transformers need the center tapped 240 to make 120 to run. Much easier to purchase a new one there, and it is probably cheaper than the transformers and less problems for a service call.
Q:What is the unit of the transformer?
KVA instead of KW? VA or KVA is the apparent power, AC line used, also known as the capacity, that is, voltage and current rms product, the unit ... but will affect the load design of the transformer, so use VA or KVA to calculate more accurate. And W or KW is our usual habit of the law, written formal.
I haven't a clue as to who told you that. The lower voltage would tend to hold you to the wires, where the higher voltage would push you away. The only real difference is that the higher voltage could arc to you, where the lower voltage at the same distance would not.
Q:Can someone explain transformers for me please?
A step UP transformer is used to boost the VOLTAGE, as by doing so the CURRENT is reduced by the same factor, e.g. boost voltage by 100 x, reduces current to 1/100th. By reducing current, power losses due to the transmission line RESISTANCE is very significantly reduced, especially in long run distances between consumers and the generating plant. The formula I^2*R is power, and the square of (say) 100A is 10,000, whereas if the current were reduced by 100 fold as above, the current becomes 1A., so you can see the difference! 1^2 1, versus 100^2 10,000. But the voltage is too high for consumer use, So a step DOWN transformer is used to change the voltage down to the required domestic voltage. The ratio of this transformer can easily be adjusted to allow for the minute power lost in the high voltage lines. The overall effect is very much less power lost in heating the connecting wires in the transmission lines, so much more power available to consumers.
Q:Please could someone assist on electrical transformers?
To improve the performance of a transformer, you have to:- [1] Reduce the copper losses, and [2] reduce the iron losses. Copper losses can be reduced by using copper wire of the highest purity; and by using copper wire that has the thinnest possible layer of insulating material on it. These measures, taken together, reduce the length of the wire and therefore its resistance. Iron losses are reduced by using magnetically soft iron in the laminations. This is the type of iron that has a tall and narrow hysteresis loop. Using copper wire with thin insulation (as mentioned above), keeps the windings close to the iron and so reduces magnetic leakage. A third measure is to use very thin laminations and to insulate them with very thin material as this will reduce eddy currents. It is very expensive to build a 99% efficient 250 MVA transformer. The losses in a 94% efficient version, are often cheaper to manage than the extra cost of making the 99% version.
Q:Transformer specifications trouble?
If you want a different amplitude without using a resistor network, you probably need to transform before you rectify. You need a little more than half of the voltage you are starting with so not quite a 2:1 turns ratio. Make sure you have big enough wires for 60 A or they will get too hot.
Q:Indoor/outdoor distribution transformer?
Everyone wants to live in a wonderful residence with fashionable and unique framework and if you are one of those folks and you have the spot and time to do your personal landscaping why don’t you make your ideal perform with a good deal of assist from here
Q:Do transformers use electricity when the appliances aren't turned on?
Yes they use electricity
Q:can i make a transformer with the help of chemical?name the chemical pls or any books websites for it?pls help?
A transformer can only work efficiently if it use a SOFT-IRON CORE. In chemistry any matter is considered a chemical. SO, the chemical' we're talking about is the soft-iron core.
Q:Load Loss of Transformer?
Yes this is right. There are two losses in a power transformer: iron losses and copper losses. Iron losses in the core depend on the flux (hence the voltage) and the frequency. The copper losses come from I^2*R losses in the windings, so they depend on the load current. The flux in the core doesnt change when we change the load, only the current through the windings, so your reasoning is correct.
