1. Introduction to shunt reactors. Shunt reactors are used in high voltage systems to compensate for the capacitive generation of long overhead lines or extended cable networks.The reasons for using shunt reactors are mainly two. The first reason is to limit the overvoltages and the second reason is to limit the transfer of reactive power in the network.
Power capacitors play a key role in providing an inactive reactive power source within electrical distribution systems. They include two conducting plates which are separated

The capacitor is an open circuit for the DC voltage/current from the previous stage, but it allows the higher frequency AC signal to pass to the next stage. If you remove the entry capacitor to a new stage, the DC voltage from the previous stage will displace the operating point of the new stage, which will not operate properly.
