Capacitors and Reactors are used in transmission systems to control
voltage as given below. Select the correct choice :
Series capacitors and shunt reactors for leading power factors
Shunt capacitors when - power factors leading and series reactors when
power factor lagging.
Shunt capacitors when power factors lagging and series reactors when
power factors is leading
Shunt capacitors and series reactors for leading power factors
Shunt capacitors when power factors lagging and series reactors when
power factors is leading
Shunt capacitor : The magnitude of voltage at the bus is less than the required magnitude then the shunt capacitor is connected. It's use in power factor Improvement.
Shunt reactor : The magnitude of voltage at the bus is more than the required magnitude (i.e. mean Ferranti effect) then the shunt reactor is connected in transmission line.
Series Reactor : Series reactor are connected
to the system in series they are normally used to limit the fault current in the
system or to facilitate proper load sharing in a parallel power network.
