Abstract
Abstract 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.
