ACTIVE HARMONIC FILTERS (AHF)

Active Harmonic Filters (AHF) are power quality devices that monitor the nonlinear load and dynamically provide controlled current injection, which cancels out the harmonic currents in the electrical system. They also correct poor displacement p...

HARMONIC FILTER DESIGN CONSIDERATIONS BY IEEE 1531

IEEE 1531 has outlined key harmonic filter design considerations for its proper selection. They are grouped into performance and rating criteria. The former relate to normal expected operating conditions. Meanwhile, the rating criteria refer to unusu...

ETAP TUTORIALS: HARMONIC FILTERS & SIZING

The purpose of this ETAP Tutorial is to show how to size a shunt passive harmonic filter using the Harmonics Module. It illustrates the advantage of using the ETAP software to improve the speed and accuracy in conducting the power quality s...

OVERVIEW OF PASSIVE HARMONIC FILTERS

Passive Harmonic Filters are currently the most common method used to control the flow of harmonic currents. They are built using a series of capacitors (capacitance) and reactors (inductance) forming an LC circuit in parallel with the power source.
