Explanation / Answer

1)

KVA ( Kilovolt ampere)

The KVA rating of transformer is referred as transformer size. As it is calculated based on KVA of Load.

3) Source current

As current is voltage divided by impedance.

Isource = Vsource/Zsource

4) The current described in 3) is Ideal source current.source.

5) The two conditions are

i) The fusing current of fuse is higher tnan current of device for proper working. Fusing current is the minimum value of current at which the Fuse melts. Since fusing current of fuse is higher it does not melts even electric device is faulted.

ii) The fuse is connected in parallel to the electric device. So, even if the fuse has broken the faulted electric device is connected with the supply.
