Reactor Use

In a substation what is the use of shunt inductive reactor i mean there is always a demand of capacitive reactance in industrial substation right?

Shunt reactors are used to compensate ferranti effect for excessive shunt capacitance on long, lightly-loaded transmission circuits and compensate the leading reactive power of the lines (power factor correction).

For Feranti effect see: http://tkne.net/downloads/power/transmissionlines1/transmission%20lines/_Ferranti%20Effect.pdf

for a long transmission line, line itself act as a capacitor and at sometimes at no load receivind end voltage might become greater than sending end....

to avoid this situation shunt reactors are used at power substatio
