Question: Three single-phase transformers, each rated 75 kVA, are connected in to power a three-phase 225-kVA load. If one of them is removed for repairs,

Three single-phase transformers, each rated 75 kVA, are connected in Δ–Δ to power a three-phase 225-kVA load. If one of them is removed for repairs, determine:

(1) The line voltage and line current on the load side and

(2) The maximum kilovolt-ampere load that the remaining two transformers can provide.
