Not unless you're energizing from the low tension side, then loading on the high tension side . . . which I've seen done as a routine practice often enough to not flat-out dismiss the possibility.
I am sorry to ask again for clarity. Is it because the primary side of t/f will draw the inrush current to develop the magnetic flux? That’s why impact will be seen majorly on the primary side, not on secondary.
Using the convention that the primary side of the transformer is the supply side, the secondary will not see the transformer inrush. The secondary will see any inrush caused by loads that are connected when the transformer is energized.
I was referring to the "conventional" configuration in my response, and specifically intended to say "placing on potential with the secondary [ LT ] breaker, and loading on the HT side by some appropriate means."
I have also seen GSU Txs direct connected to the generator's "isolated phase bus" without LT breaker, where the trafo is slowly brought to operating potential along with its associated generator . . . but I do not understand that scenario to be in play in the situation being described.
If a motor or another transformer is connected to the transformer secondary, the inrush of that equipment will be seen by the transformer secondary.
Consider a distribution circuit being re-energized after an outage. All of those refrigerator and furnace fan motors trying to start at once.
