Three single$-$phase transformers are connected in $-$ to step down a line voltage of $230$ kV to $27\mathrm{.}6$ kV to supply power to a manufacturing plant. The plant draws $60$ MW at a lagging power factor of $88\%.$ Calculate:

$$

a$)$ The total apparent power drawn by the load$$

b$)$ The line current in the HV side$$

c$)$ The line current in the LV side$$

d$)$ The phase currents in both primary and secondary$$
