Why are transmission lines multiples of 11? Is it because of
some historic reason ? Or is there a scientific base to it?
Answer Posted / hemant kumar
the reason is that because at the generation station voltage
is generated at 11KV.so that it is a base label for
transmission purpose.at each stage it can amplified by step
up transformer as multiple of 11Kv like 33kv,66kv etc.
