<p>A town situated 20 km away from a power plant generating power at 440V, requires 600 kW of electric power at 200V. The resistance of the two wire line carrying power is 0.4&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;per km. The town gets power from the line through a 3000 - 220 V step down transformer at a substation in the town.</p>

<p>(i) Find the line power losses in the form of heat.</p>

<p>(ii) How much power must the plant supply, assuming there is negligible power loss due to leakage?</p>
