a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.

The KVA rating of a transformer is based on how much heat the transformer can dissipate. The BIL rating is based on how well the windings are insulated. There are other "ratings" as well. Rough calculations can be done, but tests are generally performed to prove the calculations (transformer designers will design on the conservative side to insure the transformer meets specification). These type of calculations are best done by a computer. You will struggle to determine the hot spot max temperature rise in a transformer by hand.
Without knowing the type of transformer (audio/power, step-up, step-down, etc.) it's difficult to offer any advice.

If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
This type of a transformer is known as a step up transformer.
its a type of transformer oil which provides insulation ...
Stepdown Transformer.
step-down transformer
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
A resistance furnace runs on electricity so it will be some type of electrical transformer.
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
