Harmonics / K-factor Ratings
Published by Siemens Canada, Siemens Limited Power Product Catalogue, Canadian Edition 2019. Section 18 – Technical, Contents: Harmonics / K-factor Ratings (18-16, 18-17) Non-Linear Loads When a sinusoidal voltage is applied to a linear load, the resultant current waveform takes on the shape of a sine wave as well. Typical linear loads are resistive heatingContinue reading “Harmonics / K-factor Ratings”
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?”
