    Capacitor bank switching explosion

    In the filter banks, the capacitor units are connected in series with inductors. Sometimes the voltage across the capacitor units exceeds the design values. In such circumstances, the capacitor units fail catastrophically due to inadequate voltage rating. The blowing of a fuse may be due to short circuit in a capacitor unit, overcurrent due to an overvoltage, or harmonics. A short-circuited capacitor unit can. Capacitors operated at extreme hot conditions can fail due to excessive temperature. The excessive heat can be due to high ambient temperature, radiated heat from adjacent equipment, or extra losses. Any nonlinear load in the systemsuch as an arc furnace or converter equipment produces harmonics. Filters are used to control the harmonics. It's very important that capacitor banks are installed on the best possible location in. The capacitor banks tend to interact with the source or transformer inductance and produce ferroresonance. This can produce undamped oscillations in.
