摘要： An apparatus for the detection of a current in a protection and metering current range comprises one current sensor (1), which generates a voltage signal, and a voltagelimited electronic element (7). For metering voltage signals exceeding the upper metering voltage limit of the electronic element or for protection voltage signals exceeding the upper protection voltage limit of the electronic element an attenuation element (3) with an attenuationn factor being larger than unity is electrically connected to the current sensor (1). The attenuation factor is chosen in such a way that the metering voltage signal divided by the attenuation factor is smaller than or equal to the upper electronic element metering voltage limit or the protection voltage signal divided by the attenuation factor is smaller than or equal to the upper electronic element protection voltage limit.

摘要： An arrangement for reading out an analogue voltage signal (V in ) comprises a voltage signal input (I) for applying the analogue voltage signal (V in ) thereto, reference means (ref) for generating an analogue reference voltage (V ref ) and converting means (ADC) for converting an analogue input signal (1 ) into a digital output signal (2). In order to enable online self calibration of the arrangement, the arrangement further comprises superposition means (sup) which are adapted to receive the analogue voltage signal (V in ) and the analogue reference voltage (V ref ). The superposition means (sup) contain modulation means for generating a modulated reference voltage (V mod ) from the analogue reference voltage (V ref ) and are adapted for generating a combined analogue signal (4) by superimposing the modulated reference voltage (V mod ) onto the analogue voltage signal (V in ) and for forwarding the combined analogue signal (4) to the converting means (ADC).
