33kV to 11kV transformers steps down the the voltage to a safe level, which is then distributed via 11kV feeders to homes and businesses. Many people question why the voltage is as high as 33kV in the first place. The reason is that the higher the transmission voltage, the lower the transmission losses will be.

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.
