The transformer is rated 7.2 kV -- 120 V V x 120V = V x V srated = Since the low side is connected delta, the line voltage will be equal to the coil rating of each phase V h 7.2kV = V h V prated = Since the high side is connected delta, the line voltage will be equal to the coil rating of each phase b.
