What is the function of a capacitor in series in a circuit
Mar 14, 2019

In a dc circuit, it is true that the circuit is disconnected and some energy can be stored.


In communication lines, series capacitors can provide reactive power compensation. Usually in series in 330kV and above ultra-high voltage lines, its main role is to improve system voltage from the perspective of compensating (reducing) reactance, so as to reduce power loss and improve system stability.


Series capacitors are widely used in power transmission and distribution systems, especially in long-distance and large-capacity transmission systems. They can improve the transport capacity, improve the stability of the system, improve the voltage adjustment rate of the system, improve the power factor of the system together, and reduce the line loss.
