    Open-delta connection

    Thanks very much. I am in Ghana which is in the Western part of Africa. 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

    Open-delta connection

    (1)If I want to connect a Resistor across the open-delta, what will be the safe value? (2) It was to be used for 64N protection

    Open-delta connection

    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?

    Ferro-resonant

    How do I remove ferro-resonant with two phases of VT having 34.5/115/3 and 34.5/115 connected in open-delta?

    Open-delta connection

    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?
