Customer ServiceCapacitor bank protection 1. Unbalance relay. This overcurrent relay detects an asymmetry in the capacitor bank caused by blown internal fuses, short-circuits across bushings, or between capacitor units and the racks in which they are mounted.. Each capacitor unit consist of a number of elements protected by internal fuses.
Customer ServiceSeries reactors are used with capacitor banks for two main reasons: To dampen the effect of transients during capacitor switching, and to Control the natural frequency of the capacitor bank and system impedance to avoid resonance or
Customer ServiceCapacitor banks are often used to correct low-power-factor situations. In systems with large amounts of capacitance used to correct power factor, high-voltage distortion can cause resonance at system harmonic frequencies. This results in series-or parallel-resonant currents, which can be very damaging to the electrical system.

Customer ServiceThe 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.
Customer ServiceDetuned reactors are three-phase inductors that play a crucial role in attenuating the amplification of harmonics in networks rich in harmonics. They are also used in series with capacitor banks to prevent harmonic amplification caused by resonance.
