In a closed wye/delta bank, the configuration is designed to distribute the load evenly among the transformers. In single-phase systems connected to a three-phase transformer bank, the total load is divided across the three phases. Since a closed wye/delta connection allows for balanced load distribution, each transformer, or "power pot," in the bank will carry an equal share of the total single-phase load.

Given there are three transformers in the bank, the total load is divided equally among them. This results in each transformer carrying one-third of the total load. Therefore, it is accurate to say that each power pot carries 1/3rd of the single-phase load, which reflects the principles of balanced three-phase systems. This division ensures efficient operation and maximizes the use of the transformer capacity.
