Why use a harmonic filter reactor in a power factor correction capacitor bank ?
The use of specific filtering factor requires careful system analysis. As a general rule, filtering factor of 7% is used where imported harmonics from the power source is the main concern.
The Reactor + Capacitor combination is designed to have a Resonance Frequency below the first denomination Harmonics ( usually 5th Harmonic in a 3 Phase 3 Wire Loading System ). Hence by De-Tuning a circuit we force the Resonant Frequencies below the lowest order Harmonics present in the system. This in effect corrects PF at fundamental frequency, and at higher order Harmonic Frequency, it operates as a de-tuned system.
We provide Power Quality Analysis services also, as it is required for proper filter design. Power Quality Analysis would involve collection of data regarding Voltage, Current, PF, KW, KVA, Harmonics, ( THD Levels and Individual Harmonics ) by data logging to understand system power quality details.
