Q$.3$ Given the following data, determine the settings of the phase standard inverse$-$time overcurrent element on the $34\mathrm{.}5$ kV side of the industrial substation transformer.

Transformer data: $5$MVA,$\frac{34\mathrm{.}5}{13\mathrm{.}8}kV,Z=6\mathrm{.}5\%)$

Three$-$phase short$-$circuit currents:

$34\mathrm{.}5$ kV bus $=5000A$

$13\mathrm{.}8$ kV bus $=2572A$
