The most common role of a capacitor bank is to correct the power factor in an electrical distribution system. But several factors lower the ability of the capacitor bank to correct the power, such as temperature, moisture, harmonics, and time.
Power system operation involves many switching functions that may inject currents with different harmonic resonance frequencies. Mitigation of such harmonic sources is vital. There is no safe rule to avoid such resonant currents, but resonances above 1000 Hz will probably not cause problems except interference with telephone circuits.. This means the …
