Mirus Harmony Series Harmonic Mitigating Transformer Technical Guide

About this manual

The Mirus Harmony Series consists of Energy Efficient Harmonic Mitigating Transformers (HMT) designed to prevent voltage flat-topping and reduce energy costs. The series includes single-output (HARMONY-1), dual-output (HARMONY-2), and multi-output (HARMONY-3S & 4) models featuring phase shifting and low zero sequence impedance.

Frequently asked questions

What specific harmonics does the HARMONY-1 transformer treat within its secondary windings?

The HARMONY-1 treats triplen harmonics, specifically the 3rd, 9th, and 15th, within the secondary windings.

Which harmonics does the HARMONY-2 transformer treat inside its secondary windings?

The HARMONY-2 treats the 3rd, 5th, 7th, 9th, 15th, 17th, and 19th harmonics within its secondary windings.

What is the typical voltage for line-to-neutral rectifier loads that produce triplen harmonics?

Typical line-to-neutral rectifier loads operate at 120VAC and produce current harmonics including the 3rd, 5th, 7th, 9th, and higher.
