4) The flux linkage or a transformer is the sum of the flux passing through each turn in the coil added over all the turns of the coil. 5) All the flux produced in the primary coil of a transformer also passes through the secondary coil. 6) When calculating the transformer voltage regulation, the effects of the excitation branch can be ignored, and only the series impedances need to be considered.

The core of a transformer operating at 50 Hz has an eddy current loss of 100 W/m3 and the corelaminations have a thickness of 0.50 mm. The core is redesigned so as to operate with the same eddycurrent loss but at a different voltage and at a frequency of 250 Hz. Assuming that at the new voltage themaximum flux density is one-third of its original value and the resistivity of the core remains unaltered,determine the necessary new thickness of the laminations.
