Process and system for operating and monitoring via their power distribution network discontinuously driven electrical loads

摘要

The method involves controlling loads over a provided AC voltage supply in an AC power distribution network, whereby operating pauses are provided, in which all loads are, or can be, switched off, and in which the AC voltage supply is at least occasionally supplied on the network. An amplitude of individual half-waves or half-wave groups of the AC voltage supply, are changed during the operating pauses, to transmit an information over the network. The information is preferably transferred as a binary signal, whereby the amplitude of one, preferably an uneven amount of half-waves, is reduced or switched off, for the transmission of a determined binary value.
