What is meant by Reactor in power system and what are the
uses?
Answer Posted / paritosh singha
reactor is mainly used in high voltage long transmission
line (above 200km)to compensate the ferranti effect i.e to
minimise the capacitive effect.now a line should only have a
resistance in it.but due to long transmission capacitance
comes into effect.so to nullify it we add a specific
amount(say 50 mvr)of reactor in it.

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.
