An offshore wind turbine generator produces electricity at a voltage of 3,300 V3,300\text{ V}3,300 V. A step-up transformer at the turbine platform increases this voltage to 132,000 V132,000\text{ V}132,000 V for transmission to the mainland grid.

Explain how the design and operation of this transformer enables the voltage to be stepped up from 3,300 V3,300\text{ V}3,300 V to 132,000 V132,000\text{ V}132,000 V.

Your answer should include:

  • details of the structure of this transformer
  • how a transformer works, using the principles of electromagnetic induction
  • how the design of this transformer ensures that the exact target voltage of 132,000 V132,000\text{ V}132,000 V is achieved.
