Patent ID: 8711531

Claim:
An electrical installation arrangement for the operation of an electrical consumer network, comprising: at least one first switch for the predeterminable disconnection of at least one first consumer and/or a partial network from the consumer network, at least one first arc detector, comprising at least one first sensor for measuring at least one first electrical parameter in the consumer network and for the output of a first measuring signal, with the arc detector further comprising an analysis unit for the analysis and/or evaluation of the first measuring signal as a result of at least one first analytical and/or evaluation scheme for recognizing an arc or at least an electrical effect of the arc on the electrical consumer network, at least one first tripping unit, which upon detection of an arc by the arc detector switches off the first switch and thereby disconnects the consumer and/or the partial network from the consumer network, wherein a second analytical and/or evaluation scheme is provided, wherein the first analytical and/or evaluation scheme has a higher sensitivity than the second analytical and/or evaluation scheme, wherein the second analytical and/or evaluation scheme is provided in the presence of a first living being of a predeterminable type in a predeterminable first surrounding area around the first consumer and/or the partial network, and wherein the first analytical and/or evaluation scheme is provided in the absence of the first living being in the first surrounding area.
