Describe humming loss in a transformer
WebApr 15, 2024 · 2. Core Loss or Iron loss. Sometimes, core loss is known as ‘Magnetizing current Loss’ or Constant Loss‘.. It is caused by the generated alternating flux in the transformer core. It depends on the core construction and magnetic properties of the core materials like lamination, winding thickness, lamination resistance, component density. WebFollowing are the losses in a transformer : (1) Copper /Load/Ohmic loss: Load losses is due to ohmic resistance of the transformer wingdings. These losses varied according to the load and known hence it is also known as variable losses. Copper losses vary as the square of the load current.
