Power line voltage measurement modulated transmission system
First Claim
1. MEANS FOR MEASURING THE FLOW OF CURRENT IN A CONDUCTOR AND TRANSMITTING TO A REMOTE POINT A SIGNAL VARYING ACCORDING TO THE MAGNETIC OF SAID CURRENT FLOW COMPRISING, IN COMBINATION, A RADIO TRANSMITTER OPERATING AT A PREDETERMINED HIGH FREQUENCY AND ENERGIZED BY CURRENT FLOW THROUGH SAID CONDUCTOR, A LOW FREQUENCY GENERATOR ENERGIZED BY CURRENT FLOW THROUGH SAID CONDUCTOR TO GENERATE A PREDETERMINED LOW FREQUENCY FOR MODULATING SAID HIGH FREQUENCY, AND MEANS CONTROLLED BY CURRENT FLOW THROUGH SAID CONDUCTOR FOR CAUSING SAID LOW FREQUENCY GENERATOR TO GENERATE A SERIES OF PULSES OF SAID LOW FREQUENCY WITH THE NUMBNER OF PULSES OF SAID LOW FREQUENCY PER UNIT TIME BEING A FUNCTION OF THE MAGNITUDE OF THE CURRENT FLOW IN SAID CONDUCTOR.
