Open-delta connection
Open-delta connection
(OP)
I have a 34.5kV VTs with two windings. One of the windings is 34.5/115 and the other 34.5/115/3. One of the phases had 34.5/115 and the others have 34.5/115/3. how do I connect the open-delta to get a balance voltage?






RE: Open-delta connection
An open delta connection would be one VT connected A-B and a second VT connected B-C. The B phase of the secondary would be grounded. Or, do you mean a broken delta connection using 3 VTs connected in wye on the 34.5kV side and in delta on the low-side with a loading resistor in one corner?
