Calculate the ratio of the number of turns on the primary coil and the number of turns on the secondary coil for the transformer in the following case.

A generator at the Bayswater power station produces 220MW of power in a single phase at 23kV. This voltage is stepped up to 330kV by a transformer in the transmission substation.

For a transformer the ratio of the voltage induced the secondary coil to the voltage in the primary coil is equal to the ratio of the number of turns in the secondary coil to the number of turns in the primary coil.

The generator in the power station produces power at 23 kV. This is stepped up to 330 kV by the transformer.

The ratio of the number of turns in the primary coil and the number of turns on the secondary coil is equal to `330/23 ~~ 14.3478`

The required ratio of the number of turns in the primary coil and the number of turns in the secondary coil is `330/23` .

Transformer changes 216 V across the primary to 12 V across the secondary. If the secondary coil has 10 turns, how many turns does the primary coil have?
