In the presence of harmonics, the total power factor is defined as total power factor = TPF = cos0 = Ptotal Stotal (5-6) where Ptotal and Stota1 are defined in Eq. 5-4. Since capacitors only provide reactive power at the funda- mental frequency, they cannot correct the power factor in the presence of harmonics.
If any harmonic source generates currents near this resonant frequency, they will flow through the low-impedance path, causing interfer- ence in communication circuits along the resonant path, as well as excessive voltage distortion at the capacitor. Capacitor Bank Behaves as a Harmonic Source.
Capacitor Bank Behaves as a Harmonic Source. There are many capacitor banks installed in indus- trial and overhead distribution systems. Each capaci- tor bank is a source of harmonic currents of order h, which is determined by the system short-circuit impedance (at the capacitor location) and the capac- itor size.
The effect is to increase the heating and dielectric stress. ANSI/IEEE , IEC, and European [e.g., 11, 12] standards provide limits for voltage, currents, and reactive power of capacitor banks. This can be used to determine the maximum allowable harmonic levels.
Too large voltage, current, and reactive power harmonics induce capacitor failures. In most cases triplen and even harmonics do not exist in a three-phase system. However, there are conditions where triplen harmonics are not of the zero-sequence type and they can occur within three-phase systems.
