A new industrial development has decided to'use two 350 kVA single-phase transformers to serve as an interim 3-phase 13.2 kVu- 600 V step-down transformer bank. The transformers are to be connected open-delta on the HV side and open-delta on the LV side. (a) What are the voltage ratings of the two single-phase transformers? Determine the maximum balanced three-phase apparent power load that can be continuously supplied by this bank. (b) (c) If at a later date a third identical single-phase transformer is added to the bank, what will be the new three-phase apparent rating of the completed delta-delta bank?

10. A three-phase transformer consists of a bank of single-phase transformers connected to form a Dd0 connection. A fault on one of the transformers causes it to be removed from the circuit, and the remaining two transformers are connected in an open-delta (V-V) connection. Show that the capacity of the open-delta connected transformers is 58% of the delta-connected transformers.
