Am I not safe from harmonics if I use K-Rated transformers and oversized neutrals?

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. K-Rated transformers made their appearance several years ago as a means of preventing transformers from failing when subjected to heavy non-linear loading. They are essentially ‘beefed up’ transformers with extra steel in their cores andContinue reading “Am I not safe from harmonics if I use K-Rated transformers and oversized neutrals?”

How reliable are transformer energy efficiency tests (including Independent 3rd Party) under non-linear loading?

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. It is much more difficult to accurately determine the energy efficiency of a transformer under non-linear loading than it is under linear loading. The industry accepted technique for measuring transformer efficiency under linear load involvesContinue reading “How reliable are transformer energy efficiency tests (including Independent 3rd Party) under non-linear loading?”
