What effects will reverse polarity have on a closed delta bank? Will the adverse effects on equipment be instantaneous or over a period of time?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Do you mean reversed polarity of one transformer in the bank?
Very heavy secondary circulating currents and primary currents. Expect the transformer primary fuses to blow and possibly the distribution feeder to trip out. Possible transformer damage.
Negligible effect on the loads.
