Harmonic Filters & Sizing

Harmonic Filters & Sizing Analysis

Harmonic filters are extensively used to mitigate harmonic problems.

A properly designed harmonic filter can prevent the harmonic current from injecting into the system, or it can provide a low impedance path at the tuned frequency to remove a parallel resonance. The Harmonic Filter editor provides all the practical and popular filter structures for you to choose from.

Harmonic Filters & Sizing Software Key Features

Harmonic filter design & sizing
Harmonic filter sizing based on power factor correction, minimum cost, or minimum operation objectives
Automatic harmonic filter overloading checking & alert

Built-in Harmonic Filter Types

By-Pass
By-pass frequency characteristic
High-Pass Damped
High-pass with damped frequency characteristic
High-Pass Undamped
High-pass with undamped frequency characteristic
Single-Tuned
Single-tuned frequency point
3rd Order Damped
Special high-pass damped filter where the inductance is replaced with a series LC Circuit to provide zero losses at the fundamental frequency and therefore avoiding parallel resonance
3rd Order C-Type
Special high-pass undamped filter where the inductance is replaced with a series LC Circuit to provide zero losses at the fundamental frequency and therefore avoiding parallel resonance
