munrolili Posted February 11, 2016 Share Posted February 11, 2016 How do i work out this question? The power station generates 100MW of power at a voltage of 25kV. Transformer A, which links the power station to the transmission cables, has 44 000 turn in its 275kV secondary coil. Calculate the number of turns in the primary coil of transformer A.

EdEarl Posted February 11, 2016 Share Posted February 11, 2016 This seems like a homework problem. Your problem statement is clear, but you are missing some information, but I am unsure what you need. "The ratio of turns is the same as the ratio of voltage" is enough information to answer your question--if you were born with a gift for solving word problems, or if you were not an have practiced until you have developed the skill. You may be able to write the equation with the information you now have, because the quoted underlined statement is an equation. If you cannot, you need practice in translating English into math, but I am not skilled in teaching others how to do those translations. In that case, someone else may better help you.
