Typically how many turns on a primary winding on a 5KVA 230/110v step-down transformer?
want to use it as an example for an assignment

You need to know the frequency, core area, and the saturation flux density of the core to determine number of turns on the primary.
There are many steps to designing a transformer. It is an iterative process where you try different configurations and see which work.

Depends on the core. For a 60 Hz transformer the number of turns per volt will be about 38 turns / core area (cm²). So if the core area is 10 cm², the primary will be 3.8 turns/volt, and with a 230 volt primary that would be 230 * 3.8 = 874 turns.

MEASURE ITS CENTER CORE SIZE, THEN FOLLOW THE TRANSFORMER TURNS CALCULATION FORMULA TO FIND IT OUT.
