To calculate the kVA rating for a single-phase transformer, you''ll need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1,000: V * l / 1,000. For example, you would multiply 150 by 50 to get 7,500 and then divide that number by 1,000 to get 7.5 kVA.
