Abstract:
A circuit arrangement for measured value detection, transfer and analysis For use in a power generation circuit, said arrangement comprisinga measured value detection section including a measured value recorder, a measuring transformer circuit, a switch controller having an input and connected upstream from the measuring transformer circuit, and a first current regulator having an input and connected upstream from the switch controller in series therewith; a measured value analyzing section including a voltage source, and an analyzing circuit; a connection consisting only of an outgoing conductor, and a return conductor between the measured value detection section and the measured value analyzing section, said switch controller delivering a constant operating voltage for the measuring transformer circuit, and the first current regulator, controlled by the measuring transformer circuit, setting a measured value and power supply current flowing through the outgoing conductor and the return conductor representing the measured value, and a capacitor connected parallel to the input of the switch controller whereby the current consumption of the measuring transformer circuit is controlled in such a way that the voltage drop via the first current regulator is made as small as possible, by reducing the current consumption of the measuring transformer circuit in the short term.
