why the generating voltage in India is 11kV or why is it be
transmitted as multiples of 11
Answer Posted / a.mohanasundaram
i) Generating voltage strength (11KV) depends on dielectric strength of insulating materials to withstand heat loss produced by the main HV winding (armature). India has developed insulating material to generate maximum of 11KV (rms)
i.e) magV directly proptional to insulating material thickness
ii) Transmission votage is multiples of 11 bcaz
form factor = Vrms / Vavg=1.11 (sine wave)
to make average voltage 10 KV , rms sent as 11KV or 10% drop in voltage considered

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
