Answer Posted / pankaj
400 kV and 765 kV are not the muliple of 11 kV . Hence it
is not true that the transmission voltage must be a muliple
of 11 kV.
It is the traditional voltage at which the electrical
equipments are designed and the switchgear manufacturing
companies are not doing any R&D work. They are
manufacturing the switchgear at the same standard voltage
levels as many of the clients( PGCIL,NTPC and all state
electricity boards etc.)do copy-paste in the tender
specification and they dont want to do the hectic work to
produce the new specification.
That is the only reason that transmission is done at the
predecide voltage levels. The new voltage levels will not
be the exact multiple of 11 kV as 765 kV and 400 kV are
not.
