IMPROVEMENTS IN OR RELATING TO ARRANGEMENTS FOR MEASURING CURRENTS IN HIGH TENSION CONDUCTORS

摘要

A modulation device at a high voltage has a reflector for reflecting high frequency oscillations in accordance with the magnitude of the current to be measured. The reflector has resonant characteristics corresponding to the magnitude of the current to be measured. A transmitter transmits high frequency oscillations to the reflector. A receiver converts the reflected oscillations to signals corresponding to the magnitude of the current to be measured.
