Answer / dilip

Reactor is mainly use to compansate power system in both
underloaded (Inductive)and overloaded(Capacitive) condition

Answer / sadam gaad

reactor maintain the voltage, limiting short circuit
current, reducing capacitive MVAR, if you use it in series
it works as limiting short circuit current n if in parrallel
then it reduce ferranti effect.

Answer / vinod

FOR LONG TRANSMISSION LINES WITH LIGHT LOAD, REACTORS ARE USEFUL IN PF IMPROVEMENT. IT IS ALSO USED FOR LIMITING THE SHORT CIRCUIT CURRENT.

Answer / arvind thakur

SHUNT REACTOR IS USED IN EHV TRANSMISSION LINE TO CONTROL VOLTAGE DURING LOW LOAD PERIOD.IT IS ALSO USED FOR COMPENSATE THE SHUNT CAPACITOR OF TRANSMISSION LINE DURING LOW LOAD PERIOD...

Answer / r.mukesh

Shunt reactors are designed for connection to the ends of high voltage transmission lines or to
high-voltage cables for the purpose of controlling the line voltage by absorbing reactive power.

Answer / r.s.naidu

using of reactor in the substations because of protected
power system from the short circuit.

Answer / dost muhammad (mahsood )

All nuclear reactors are devices designed to maintain a chain Reaction producing a steady flow of Neutrons generated by the fission of heavy nuclei

Answer / muhammad naveed

Line reactors can protect motors and reduce power line distortion from VFDs.

Answer / nabeel

it s to maintain the phase angle btwn volt and current. For
power factor correction actually. Also it can be said as To
control the reactive power flow.

Answer / amit

for power factor improvement
