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.
