Anordnung zur Zuführung von Energie von Erdpotential zu einer in eine Hochspannungsleitung geschalteten, auf Hochspannungspotential angeordneten elektrischen Vorrichtung

摘要

An arrangement for supplying electric energy to operating, measuring and indicating devices placed at the potential of a high voltage line. When current flows through the line, the energy is transmitted from the line to said devices through a saturated current transformer. When the line has no load, however, the energy is transmitted from an energy source at earth potential through a rotating electric generator at high potential.
