‘Docta Reacta’ Publishes e-Book on Harmonic Filter Reactors

Docta Reacta:  I am pleased to announce that I am publishing The Power Magnetics, Inc. Institute’s first e-book.  It is entitled “Understanding the Advantage In Power Magnetics, Inc. Medium Voltage Harmonic Filter Reactors.”  It is designed to help the reader, in particular, the OEM understand the advantages to the Power Magnetics design, construction and manufacturing methods used to produce what is rapidly becoming the “defacto” industry standard for medium voltage[…]

Design Criteria for Iron Core Reactors for Harmonic Filter Bank Applications

Prafessa Reacta with you today. The design criteria for harmonic reactors are driven by the harmonic spectrum provided along with current rating, inductance, temperature rise, taps and impulse rating. The following considerations apply equally to both the single phase harmonic reactor and the three phase harmonic reactor when used in harmonic filter banks. Harmonic filter reactor current ratings are typically based on the following considerations: The reactor core will not[…]

General Specifications for Iron Core Reactors in Harmonic Filter Bank Applications

Docta Reacta:  Continuing our discussion, I thought we should provide you with some of the trade-offs when using harmonic filter reactors in harmonic filter bank applications. The construction methods for trap reactors lend themselves to a substantial flexibility in specifications and ratings.  For filter bank applications, single phase iron core reactors are most often utilized because of the flexibility and inherently higher ratings.  Copper winding is frequently chosen when performance[…]

Iron Core Reactors for Harmonic Filter Bank Applications – Part 2

Docta Reacta: Here is more enlightenment and edification on the trade-offs between three phase reactors and single phase reactors, harmonic filter reactors if you will, when used in harmonic filter banks.  Iron core reactors can be designed as either single phase or three phase.  There are trade-offs for each reactor type summarized below.   It may appear that there is a bias towards single phase reactors, and certainly these is more[…]

Iron Core Reactors for Harmonic Filter Bank Applications – Part 1

Docta Reacta:  Today I would like to provide some elucidation and enlightenment on iron core reactors when they are used in harmonic filter banks! When OEM’s are looking for high reliability filter bank reactors, it comes down to a simple choice: Power Magnetics. Why? Because we have a very long history of providing iron core reactors, sometimes called harmonic filter reactors, to the manufacturers of harmonic filter banks that go into some of the most difficult applications[…]
