50hz nh3 analysis for transformers

Operating a transformer at 50Hz generates 20% more flux lines than at 60Hz. As the number of flux lines approaches the magnetic material's limit, the heat in both the transformer's core and its coil wires increases, and under certain circumstances, unpredictably so. This can result in a transformer that exceeds safe temperature levels.

    If a transformer is not designed for both 50 and 60 Hz frequencies as the supply frequency in US is 60Hz while in EU etc are 50Hz, then: When a 60Hz transformer is being operated on 50Hz supply source, it should be derated i.e. the supply voltage must be reduced by 1/6 to reduce the peak flux in the core and reduce the heat as well.

  • Transformer Frequency, common frequencies

    More iron and/or more turns of wire are required to have the same transformer winding inductive reactance at a 50Hz frequency. As a result, power transformers designed for use in U.S. 60Hz applications run very hot, and sometimes extremely hot, if used in 50Hz power mains, even if they have windings to accommodate the higher voltages.
