Answer / gunnamsantosh
for transmission we use delta because we require 3 wires
| Is This Answer Correct ? | 11 Yes | 8 No |
DELTA Connection
as for long transmission it is economical to transfer power
with 3 wire
| Is This Answer Correct ? | 0 Yes | 1 No |
Answer / atul gupta
it is delta.
because from one to another Lilo line is there. & another
to another s/s. it is just like a mesh.
every s/s jointed in grid mesh system. so we can say it is
delta connected..

Answer / k.prakashchandra
At 400 KV stations 220/400 KV star connected auto
transformers are employed.There is no star or delta
connection applicable to trans line
| Is This Answer Correct ? | 2 Yes | 6 No |
Answer / gunnam santosh
mostly by using star because by using star we can reduce odd
harmonics
| Is This Answer Correct ? | 0 Yes | 4 No |
delta
as for long transmission it is economical to transfer power with 3 wire rather with 4 wire.
| Is This Answer Correct ? | 3 Yes | 7 No |
