ABSTRACT OF THE INVENTION Analog output signals from decentralised transducers for current and voltage are sampled with timing patterns generated at a decentralised location and are transmitted to a central evaluating facility in the form of digitally encoded data streams (DUR, ...). For the purpose of generating data sets which are each based on one sampling of each analog output signal, such that the relative time displace- ment of the samplings should not exceed a predeter- mined 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 digitised sampled value arriving next of each data stream (DUR, ...) is temporarily stored. After the temporary storage has taken place, in each case a "Ready" signal (BUR, ...) is set. The "Ready" signals (BUR, ...) are combined in a logical AND operation to form a "Data set ready" signal (DB) which is trans- ferred to a computer which interrogates the tem- porarily stored data (ZUR, ...) via a databus.
