A power transmission line feeds input power at 2300 V to a stepdowntransformer with its primary windings having 4000 turns. Whatshould be the number of turns in the secondary in order to get outputpower at 230 V?
Given: The input voltage of transformer is 2300 V , the numbers of turns in primary coil are 4000 , the output voltage of the transformer is 230 V .
The turns ratio of a transformer is given as,
N 1 N 2 = V 1 V 2
Where, the input voltage of transformer is V 1 , the output voltage is V 2 , the numbers of turns in primary coil are N 1 and the numbers of turns in secondary coil are N 2 .
By substituting the given values in the above equation, we get
4000 N 2 = 2300 230 N 2 = 400
Thus, the numbers of turns in the secondary coil are 400 .
