Jelaskan Pertimbangan parktis dari Trafo dalam bahasa sunda

Transformers are adapted to numerous engineering applications and may be classified in many ways:

By power level (from fraction of a volt-ampere(VA) to over a thousand MVA),

By application (power supply, impedance matching, circuit isolation),

By frequency range (power, audio, radio frequency(RF))

By voltage class (a few volts to about 750 kilovolts)

By cooling type (air cooled, oil filled, fan cooled, water cooled, etc.)

By purpose (distribution, rectifier, arc furnace, amplifier output, etc.).

By ratio of the number of turns in the coils

The secondary has more turns than the primary.

The secondary has fewer turns than the primary.

Intended to transform from one voltage to the same voltage. The two coils have approximately equal numbers of turns, although often there is a slight difference in the number of turns, in order to compensate for losses (otherwise the output voltage would be a little less than, rather than the same as, the input voltage).
