When a closed- delta bank is changed to operate as an open-delta bank, the capacity of the open-delta bank will be only 57.7% of the capacity of the closed-delta bank. That is, each transformer in the open-delta bank can now only be loaded to 86.6% of its actual rating. Verify with an example both ratios:
