Network Filters

Introduction

Passive filters are elements showing an identical impedance in different resistance-inductance capacitor combinations series or parallel connected. Even though these can be represented with simple passive elements, using filters has the advantage of eliminating nodes between components, thereby decreasing the number of nodes or the size of the Z matrix in the station where they are found. Meaning that the station simulation time is also decreased.

There are five types of filters available in HYPERSIM®, each offering both a series and grounding connection option:

Filter Type	Description

Filter Type	Description
C-Type	The series C-type filter is available both for 1-phase and 3-phase connections.
C-Type Grounded	The grounded C-type filter is available both for 1-phase and 3-phase connections.
Double-Damped	The series double-damped filter is available both for 1-phase and 3-phase connections.
Double-Damped Grounded	The grounded double-damped filter is available both for 1-phase and 3-phase connections.
Generic RLC	The series generic RLC filter is available both for 1-phase and 3-phase connections.
Generic RLC Grounded	The grounded generic RLC filter is available both for 1-phase and 3-phase connections.
High-Pass	The series high-pass filter is available both for 1-phase and 3-phase connections.
High-Pass Grounded	The grounded high-pass filter is available both for 1-phase and 3-phase connections.
Series-Parallel RLC	The series series-parallel RLC filter is available both for 1-phase and 3-phase connections.
Series-Parallel RLC Grounded	The grounded series-parallel RLC filter is available both for 1-phase and 3-phase connections.
