If the load of the primary side the high current is flow therefore, the circuit will be damaged so, the fuse definitely connected.

Depend upon load conditions, current flows through in primary winding. Normally primary winding voltage will be high but less current flows through primary, up-to rated current fuse will be on, above rated current flows fuse melts and stop conduction and provide equipment safe.

As primary will be connected to varying supply it must be fused and as the primary winding carries low current fuse is used as a protecting device if fuse is not used then primary coils will burn.

Power transformer in primary large current compart with secondary that's what power transformer secondary is fused.

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

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

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.

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.

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

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.
