What is Maximum Permissible Flux Density in Transformers about?
The document discusses maximum permissible flux density in transformer cores at rated voltage and frequency. It provides the following flux density limits: 1.9 Tesla for CRGO cores, 1.48T for conventional amorphous cores, and 1.56T for high permeability amorphous cores. These allow for 5-10% overfluxing as required by standards. The flux density will vary with tap position for transformers with taps and must meet overfluxing limits at all taps. Operating experience shows transformers designed to these limi
