A simple answer to this question is as here. The output energy of any electric or electronic device is expressed in power that is,a product of voltage and current. Therefore when a transformer is rated in KVA it means that the transformer is able to transmit/transfer that much amount of power. Since current is usually very small compared to voltage in any device it is expressed in KiloVoltAmp(KVA).
