What is a Harmonic Filter for Power Factor Correction in an Electrical Plant?
To ensure quality power supply in an electrical plant, Engineers know in mass the importance of Power Factor Correction equipment, and in advance Harmonic Resonance or Harmonic Filter.The standard and essential term Power Factor Improvement (PFI) or power factor correction in the Electrical Engineering sect is denoted in another previous post as Electrical Power Factor in Schematic Diagram where Electrical Power Factor in Schematic Diagram and Bangladesh Electricity Distribution Code Published by Bangladesh Energy Regulatory Commission is described briefly. So, in this article, the Harmonic Filter is highlighted only.
Harmonics are currents and voltages that are continuous multiples of the fundamental frequency 50 Hz such as 100 Hz (2nd harmonic) and 250 Hz (5th harmonic). So, the harmonic filter is used to eliminate the harmonic distortion caused by loads.
