They are used to control the capacitor discharge current and reduce the voltage across the capacitor after a bypass operation. The reactor is to limit the current since it behaves like large impedance during abrupt current transients.
Before going further on this parallel capacitor calculator, let''s start with the basics. A capacitor is essentially a device that stores energy in the form of an electric field.; Capacitors are able to store and release electrical energy, making them useful for a variety of applications, from storing power in our smartphones to regulating voltage in circuits.

In an electric power transmission grid system, switchyard reactors are large inductors installed at substations to help stabilize the power system. For transmission lines, the space between the overhead line and the ground forms a capacitor parallel to transmission line, which causes an increase in voltage as the distance increases.
While at the generating end we have capacitors in parallel or tap changing transformers to keep voltage constant. Likewise even inductors are installed in series and parallel. A series reactor is useful to limit short circuit current and starting current. A shunt reactor is useful during light loads.

When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors'' capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors. As we''ve just seen, an increase in
They are connected in series or in parallel to the capacitors on both the LV side and on the MV side. SHUNT. The shunt reactors compensate for the capacity of the long transmission lines, avoiding voltage rises in voltage at the end of the
