Electrical device e.g. power monitoring device, has detecting part for detecting electrical data, processing and displaying part for processing and displaying data, and transmitter and receiver coupled with one another by optical fiber

摘要

The device has a detecting part for detecting electrical data, and a processing and displaying part for processing and displaying the data, where the detected data is exchanged between the two parts, which respectively comprise an optical transmitter (18) and an optical receiver (22). The transmitter and the receiver are coupled with one another by an optical fiber (20) e.g. plastic optical fiber. The two parts jointly comprise a plate with two regions (12, 14) that are galvanically separated from each other, so that the optical fiber represents a single connection between the two parts.
