The inverters (1a, 1b) have internal dome switches (2a, 2b), and control-inputs (3a, 3b) coupled with a control-output (6) of a dome switch-less external network- and device protection system (5). Error signal-evaluation units (4a, 4b) evaluate a signal (S...

A scale free communication network in a power network is provided. The scale free communication network comprises a plurality of distribution devices communicatively coupled to each other in a power network that include a protection device and a controller...

An actuator control system 1 includes a controlling controller 2 and one or more driving controllers 3 connected to the controlling controller 2 via a power line 9, wherein the controlling controller 2 generates a serial signal that composites a power-supp...

The system has a control device (1) attached to a phase conductor (L) of a supply voltage source (4). Load extension modules (3.1, 3.2, 3.m) are connected between the phase conductor and a load line (L'). The load extension modules are connected with the c...

The circuit has two antiparallel diode circuits (R6,Ok1,OK2) that detect the half waves connected in series with a resistance (R1), whereby the output signals (neg, pos) of the diode circuits are separately fed to the inputs of an evaluation circuit. A pot...

The central control radio receiver has a housing in which a computer unit with a decoder unit, at least one control relay (5), a plug-in point for a long-wave receiver and a ferrite antenna are arranged. A long-wave receiver or a clock module (1) can be pl...

The present invention relates to a control apparatus for managing communications between a plurality of electric appliances connected to a household power line network. The apparatus transmits a plurality of types of modulation method control signals to ea...

The method involves a transmission device (PNU,PNC) maintaining continuous contact with at least one other transmission device. The operating state of at least one part (EVN') of the supply network (EVN) is derived from events related to the continuous con...

A system for transmitting information over a power distribution network, particularly for transmitting information between domestic appliances and/or one or more domestic appliances and a remote controller, exploits the frequency available on the power lin...
