What is an Open Delta transformer? HPS Hammond Power

PHASOR DIAGRAM OF AN OPEN-WYE/OPEN- DELTA TRANSFORMER In Fig. 1, the primary side of an open-wye/ open-delta transformer was connected to phases a and b and the secondary side to a three-phase balanced load. If a balanced volt- age source at the primary side of the trans- former is assumed, the voltage and current phasor diagram [ 1] is as shown in Fig. 2. From this Figure, it is …

The delta connected tertiary winding of transformer permits the circulation of zero sequence current in it. This circulating current in this delta winding balances the zero sequence component of unbalance load, hence prevents unnecessary development of unbalance zero sequence flux in the transformer core. In few words it can be said that, placement of tertiary winding in star-star-neutral

Open-Delta Connection Electrical Idea Transformer

transformation of energy is possible using only two single phase transformers. This connection called open-delta or V-V connection. When one phase of the three single phase transformers connected in delta-delta bank is unable to operate or damaged. Then supply to the load can be continued with the remaining two phase of transformers. This connection thus obtained is called Open Delta
