Abstract
Official abstract text for this publication.
The invention relates to a signal (feed) separator for dead-zero or live-zero measurement signals. The signal (feed) separator has a primary-side (feed) input, a secondary-side output, a direct-current transformer for transferring primary-side measurement input current, an output stage for providing a secondary-side measurement output current, and an auxiliary energy feed-in for supplying the primary side and for supplying the secondary side. The auxiliary voltage of the auxiliary energy feed-in is controlled on the secondary side by a control device with the aid of a measuring device in such a way that the power loss of the output stage is substantially independent of a load connected in the operating state.
First claim
Opening claim text (preview).
The invention claimed is: 1. A signal feed separator for dead-zero or live-zero measuring signals, comprising: a primary-side feed input; a secondary-side output; a DC transformer having a primary side and a secondary side for transferring primary-side measurement input current supplied to the primary side to secondary side measurement output current of the secondary side; an output stage comprising a transistor for providing the secondary-side measurement output current;…
