Thyristor-controlled series compensation (TCSC) systems and thyristor switched series compensation (TSSC) systems are power electronic systems developed in the late 1980s and early 1990s in response to the anticipated need for better utilization of existing high voltage overhead transmission lines because of the difficulties in getting …
Capacitor banks protection, cautions and maintenance tips
Capacitor banks reduce the phase difference between the voltage and current. A capacitor bank is used for reactive power compensation and power factor correction in the power substations. Capacitor banks are mainly used to enhance the electrical supply quality and enhance the power systems efficiency. Go back to the Contents Table ↑. 2.
In principle, shunt type compensators inject current into the system at the point of connection. Even the variable shunt impedance connected to the line voltage causes a variable current flow and hence represents injection of current into the line. ... Series capacitor compensation is an economic way of increasing the power transfer capacity …
Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the …

Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
