    Default Floating Primary Neutrals

    I have never worked where it was legit to ground the primary neutral on a 3 pot Wye/Delta bank. I have seen it done but it is considered to be the wrong way. dbrown20

    Grounding the high side of a 3 pot bank, hooked Wye/Delta can cause this bank to act as a grounding bank as all imbalance in the vicinity will travel through the bank and all faults and lightening strikes in the area will go through it also subjecting it to a greater likilhood of damage. Ever transf. book I have read mentions this always. dbrown20

    Noone got high and mighty with you. You just insisted on asking inane questions after it was repeatedly explained to you in great detail how to connect a bank. This current subject is not about how to hook one up, but actually some of the operating characteristics of such a bank. I still find it hard to believe that you work in this industry. If you will display your background in the bio. section maybe we won't be hard on you. dbrown20

    Hey... I'm not the one who got all high and mighty. I was the first one to post a reply to your original post. I truly tried to help.

    Default Uncommon hookups were not the subject, or did I missunderstand??

The 2 pot hookup must have one pot with external secondary bushings. We talked about this once before several years ago. dbrown20

    [B]I have to stand corrected, I guess. I thought I was answering an inquiry to an apprentice lineman about open as opposed to closed delta banks. I was trying hard not to confuse more someone already confused.

    To fio1024, it is not common, nor practical from your point of view to try and get a 4 wire 3 phase connection on the secondary side with 2 transformers. Use 3 transformers in your Wye secondary connections.
