What is the difference between shunt reactor and line or bus reactor?
SHUNT REACTOR
A shunt reactor is an absorber of reactive power, thus increasing the energy efficiency of the system. It is the most compact device commonly used for reactive power compensation in long high-voltage transmission lines and in cable systems
LINE REACTOR
It is a series device, which means it is connected in the supply line such that all line current flows through the reactor.
Line Reactors are current-limiting devices and oppose rapid changes in current because of their impedance. They hold down any spikes of current and limit any peak currents.
BUS REACTOR
A bus reactor is a type of air core inductor, or in some cases, oil filled, connected between two buses or two sections of the same bus in order to limit the voltage transients on either bus. It is installed in a bus to maintain system voltage when the load of the bus changes. It adds inductance to the system to offset the capacitance of the line which varies due to load, humidity, weather, generator excitation and temperature
