Why Transformer Rating In kVA, Not in KW?

Why Transformer Rating In kVA, Not in KW?In Simple words,  There are two type of losses in a transformer: 1. Copper Losses2. Iron Losses or Core Losses or  Insulation LossesCopper losses ( I²R)depends on Current which passing through transformer winding while Iron Losses or Core Losses or  Insulation Losses depends on Voltage. That’s why the Transformer Rating may be expressed in...

Why we are use 11KV / 22KV / 33KV / 66KV / 110KV / 230KV / 440KV this type of ratio?

Why we are use 11KV / 22KV / 33KV / 66KV / 110KV / 230KV / 440KV this type of ratio. Why can’t we use other voltage ratio like 54KV / 99KV etc? When an alternator generates voltage, we always use a multiple of 1.11 because for a pure sine wave the FORM FACTOR is the  ratio of rms value...
