$(1$ point$)$ A generator supplies a motor through a Y$$Y$$ transformer. The generator is connected to the YY side of the transformer. A fault occurs between the motor terminals and the transformer. The symmetrical components of the subtransient currents in the motor flowing toward the fault are

I$(1)$a$=(0\mathrm{.}82\mathrm{.}4$j$)$p$.$u$.$Ia$(1)=(0\mathrm{.}82\mathrm{.}4$j$)$p$.$u$.$

I$(2)$a$=(2$j$)$p$.$u$.$
