How do Harmonic Mitigating Transformers save energy?
Published by Mirus International Inc., [2010-01-08] MIRUS-FAQ001-B2, FAQ’s Harmonic Mitigating Transformers, 31 Sun Pac Blvd., Brampton, Ontario, Canada. L6S 5P6. Harmonic Mitigating Transformers save energy by reducing losses in the following ways: 1. Zero phase sequence harmonic fluxes are canceled by the transformers secondary windings. This prevents triplen harmonic currents from being induced into theContinue reading “How do Harmonic Mitigating Transformers save energy?”

How do Harmonic Mitigating Transformers reduce voltage distortion?
Published by Mirus International Inc., [2010-01-08] MIRUS-FAQ001-B2, FAQ’s Harmonic Mitigating Transformers, 31 Sun Pac Blvd., Brampton, Ontario, Canada. L6S 5P6. Delta-wye transformers, even those with a high K-factor rating, generally present high impedance to the flow of harmonic currents created by the non-linear loads. Question 8 showed that the non-linear loads are current sources thatContinue reading “How do Harmonic Mitigating Transformers reduce voltage distortion?”
