Open-delta connection
Open-delta connection
(OP)
I have VTs of A, b, and C phases to be connected open-delta. The ratios are 115/3 for both A & B phases and 115 for C phase. What will be the effect and what can I do?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

In North America an open delta is as davidbeach has described; two transformers used for delivery of three phase power for generally small loads.
In Europe an open delta is three transformers in delta with one corner of the delta open. This connection is called a broken delta in north America. For this connection you must start with three transformers with equal ratios. It is not a good idea to mix 115 Volt transformers with 3 Volt transformers.

It is not a good idea, but if it happen, what will be the effect? 115/root3 for A & B phases and 115 for C phase
