The reactor also helps to balance the current flow between the capacitors in the bank by limiting the current flow to the capacitor with the lowest impedance. However, the insertion of the reactor also raises the voltage across the capacitor, which can lead to increased voltage stress and a need for a higher voltage rating of the capacitor.
Capacitor discharge using reactor. Traditional discharge resistors may take up to a minute for discharging capacitors at LV and up to 5 minutes at MV. For many applications requiring frequent switching, this time unacceptably long and another faster method would be preferred. Link to: Inductance calculator
The harmonic filter (Detuned) is to limit the flow of harmonic current from non-linear loads on the reactor to the fixed impedance loads (eg capacitor). Formula 1 – Calculation of Capacitor Impedance. If we look to the impedance equation of the capacitor, it is seen that the capacitor impedance decreases with the increase of the frequency.

A bus reactor is an air core inductor, or oil filled inductor, connected between two buses or two sections of the same bus 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.
The capacitor reactance is generally applied to the system by using static capacitor in shut or series with system. Instead of using a single unit of capacitor per phase of the system, it is quite effective to use a bank of capacitor units, in the view of maintenance and erection. This group or bank of capacitor units is known as capacitor bank.

Nominal voltage of the capacitor [V]: the connection, in series, of capacitor and reactor causes an increase in voltage at the capacitor terminals due to the Ferranti Effect that must be considered in choosing the right component. The rated power of the capacitor [Q]: the power that the capacitor can generate when supplied with the rated voltage.
The inductive reactance (XL) of a reactor is directly proportional to frequency. The magnitude of inductive reactance will increase with high frequency harmonics thus blocking the harmonic current. Hence, the use of detuned reactors in series with capacitors offers higher impedance for harmonics, thus eliminating the risk of overload in capacitors.
The resulting tuned frequency of the bank is 189 Hz - at this frequency, the reactor and capacitor have equal reactance. Other detuning types commonly used are 6 %, 5 % or 14 % in cases where third harmonic distortion is expected. A 7 % reactor in this case equates to an inductance of 7.25 mH.
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.

The use of a reactor in series with the capacitors will reduce the harmonic effects in a power network, as well as their effect on other circuits in the vicinity, such as a telecommunication network.
In this case, using a reactor creates a voltage surge on the terminals of the associated capacitor and the capacitor power supply voltage Uc will be calculated as follows: Uc = Us / (1-p) Note:
By using a shunt reactor, you can reappropriate the produced power and then bring down the voltage levels so they remain at tolerable levels which won''t disturb the overall system functionality. In the second scenario, some substations rely on solid or stiff systems where generated fault currents can overrun circuit breakers and capacitor banks.
After the opening operation, the voltage on the capacitor side is higher than the system voltage (Figure B-18), so that the recovery voltage is higher in contrast to capacitors without a reactor. The rated voltage of the breaker must not be exceeded by this effect.

Air core reactors developed for this application are designed using multi-wire cable design (MCD) cables, which offer low losses. The MCD technology reactor''s winding consists of insulated aluminum stranded cables and follows a very similar manufacturing process to FED.
main reason is that with line reactors, the voltage at the VFD terminals becomes flat-topped, and the charging time for the DC bus capacitor increases, thereby increasing the current pulse width while decreasing its peak amplitude.
