Answer / bhavanan

 By power capacity: from a fraction of a volt-ampere (VA) to over a thousand MVA;
 By frequency range: power-, audio-, or radio frequency;
 By voltage class: from a few volts to hundreds of kilovolts;
 By cooling type: air-cooled, oil-filled, fan-cooled, or water-cooled;
 By application: such as power supply, impedance matching, output voltage and current stabilizer, or circuit isolation;
 By purpose: distribution, rectifier, arc furnace, amplifier output, etc.;
 By winding turns ratio: step-up, step-down, isolating with equal or near-equal ratio, variable, multiple windings.
