All methods mentioned help with limiting the fault current. The cheapest though is a neutral inductor, especially when mounted directly on the transformer. Learn more.
Current limiting fuses directly on the transformer secondary are rare. Mostly because of the continuous current requirement (1000amps or more) – fuses are rarely fabricated this large. This was a trap answer.
