As primary voltage of power transformer is very high it should be definitely fused.

It should be fused. Else the winding gets damaged.

In high voltage side has less current so fuse is enough to break the circuit safely.

Above answer not a sufficient, first closed circuit it produced flux then need a fused, it circuit is not produceflux in core.

Why because, the incoming supply voltage is varying. It may not be constant, So we need fuse to save the transformer and inorder to limit the initial current, we use fuse.

It should be fused because on the primary side always varying supply provided.

The power transfoemer rating is very high greater than 1MVA so cost of the equipment is very high. So to protech the transformer from any abnormal currents it should be protected by fuses.
In addition to fuses we use some other protecting equipments like LA (lightning arrester) etc.

When the secondary loaded is over loaded, it means draws max. Current in the primary side due to which damaged the primary side as wellas appliances. So that power t/f is fused the circuit.

Primary side voltage is very high.
So, Primary winding should be fused.

In power transformer the primary side supply is relatively very high compared to ordinary transformer so obviously FUSE is used in primary.
