four wire connection in delta system
four wire connection in delta system
(OP)
Hi all,
Hi everyone,
I have voltage regulating transformer, 27.6kV/27.6Kv, Delta/ star.
This transformer need to connect in 4 wire system both sides (Supply and load)
I can connect 4 wire to star side of transformer. But in delta side of transformer where I should connect neutral wire?
Thanks all in advance for the reply

You may wish to ground the primary side neutral, depending on your system configuration and grounding methods.

RE: four wire connection in delta system
Thank you very much for the clue. In which condition we can ground the primary side neutral ? Is there any related links, useful books?
In my case, the Transformer is in substation and has mesh earthing. The primary side is coming from a transformer ( sytar/star with neutral ground) located in a 10 km far substation.
RE: four wire connection in delta system
In the US, for a typical utility distribution feeder the neutral is grounded at just about every opportunity. But there are approaches where the neutral is only grounded at the source.
