  • Universal measurement input for connecting a small signal transformer and electrical device with such a measurement input
    Patent number: 11892474
    Abstract: A universal measurement input for connecting a small signal transformer to an electrical device includes an electrical input for connecting a connection line of the small signal transformer, an electrical output for outputting a measurement signal to the electrical device, and a correction element having a digital filter with a filter transfer function adapted to the small signal transformer. In order to provide a measurement input with which all possible types of small signal transformers can be connected to an electrical device and which thus reduces the device variety of measurement inputs which are to be provided, the filter transfer function of the correction element is defined by a parameter set to be variably preset specifically for the small signal transformer. An electrical device with the measurement input is also provided.
