Operation method for a receiver fed with information transmitted over electric supply network and arrangement for carrying it.

摘要

The receiver (3) is connected to a first phase of the electrical power supply network (2) from which it is fed exclusively with the transmitted information items. At least one event is monitored in the phases of the electrical power supply network (2), the occurrence of which event in one of the phases exacerbates or renders impossible correct reception of the transmitted information items in the receiver (3) when the latter is fed exclusively from the relevant phase with the transmitted information items. The arrangement (1) is driven via in each case one voltage divider (9, 10, 11) per phase and contains a controller (8), a switching arrangement (15; 16; 17) and in each case one event monitoring arrangement (12, 13, 14) per phase. The arrangement contains in each case one event detector (25, 26, 27) and in each case one event counter (28, 29, 30) per monitored event. The method and the arrangement (1) produce statements on the quality of the transmission and of the transmission path, which statements can be used, inter alia, for statistical purposes, for saving temporarily stored measurement data in a non-volatile memory and for switching over the transmission path.
