Abstract
Analog output signals from decentralized transducers for current and voltage are sampled with timing patterns generated at a decentralized location and are transmitted to a central evaluating facility in the form of digitally encoded data streams (D.sub.UR, . . . ). For the purpose of generating data sets which are each based on one sampling of each analog output signal, such that the relative time displacement of the samplings should not exceed a predetermined value which corresponds to the maximum (.DELTA.) of the data-refresh intervals, latch commands (L) are generated at greater intervals in the central evaluating facility, following which in each case the digitized sampled value arriving next of each data stream (D.sub.UR, . . . ) is temporarily stored. After the temporary storage has taken place, in each case a 'Ready' signal (B.sub.UR, . . . ) is set. The 'Ready' signals (B.sub.UR, . . . ) are combined in a logical AND operation to form a 'Data set ready' signal (DB) which is transferred to a computer which interrogates the temporarily stored data (Z.sub.UR, . . . ) via a databus.
