There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.
Using a transformer.
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..
Transformer Power Supply
To continuously supply a load of up to 30-V.A at the rated secondary voltage of the transformer.
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
Oil is used to cool the transformer. There is no telling what the transformer in question uses without knowing the specific part number and looking up the specification.
If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.

A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.
It uses electromagnetic induction to transfer energy between separate circuits.
