in 33KV or 66KV system which connection is aviable on high
voltage transformer primary delta or star ?
Answer Posted / amit
the question is incomplete it should mention weather it is
load end or at generating end.
at generation end primary will be delta and to nullify
generator harmonic and secondary should be star for
transmisssion line protection as it requires distance
protection.
In load end primary is star and secondary may vary
depending on load condition as load may be 3phase balance
or 3 phase unbalanced load,wether neutral is required or
not.
