Question 46

Electrical power is transmitted along overhead cables at a high voltage of 132 kV132\text{ kV}132 kV. A step-down transformer at a local substation reduces this voltage to 11 kV11\text{ kV}11 kV for distribution. The secondary coil of this transformer has 450 turns. Calculate the number of turns on the primary coil of this transformer.
