Energieversorgung und Signalübertragung für Messtechnik auf Hochspannungspotential

摘要

The apparatus has a measuring system found at a high voltage potential, and transformers with primary and secondary windings placed in a common housing (12) to transfer electric energy and/or data. Primary winding of one transformer is at a ground potential and is connected to a control unit and/or supply unit and/or evaluation unit. Secondary winding of one transformer is at a high-voltage potential and is connected to the system. Each transformer is a fiber optic cable.
