要約(日本語): After a no-loaded transformer de-energization a residual flux remains within the transformer core. This residual flux becomes important during the re-energization of a transformer system, because large inrush currents and voltage disturbances have to be expected for a complete random re-energization. The residual flux is typically approximated by the integral of the voltage measurement at the transformer terminal. If the voltage measurement is not available, an interpolation based on a limited set of voltage measurements can be considered as residual flux approximation. This paper illustrates an advanced interpolation method by a neuronal network of the type Perceptron.
