Claim 1
Independent Claim
125 words
IN AN ELECTRICAL SYSTEM, A SOURCE OF ALTERNATING VOLTAGE HAVING A FREQUENCY VARIABLE IN ACCORDANCE WITH THE MAGNITUDE OF A MEASURED QUANTITY, CONVERTER MEANS CONNECTED FOR ENERGIZATING FROM SAID SOURCE TO PRODUCE A DIRECT VOLTAGE HAVING A MAGNITUDE DEPENDENT UPON SAID FREQUENCY, A MEASURING INSTRUMENT CONNECTED FOR ENERGIZATION IN ACCORDANCE WITH SAID DIRECT VOLTAGE MAGNITUDE TO PROVIDE AN INDICATION OF SAID FREQUENCY, SAID INSTRUMENT BEING ACTUATED SUBSTANTIALLY INDEPENDENTLY OF THE MAGNITUDE OF SAID SOURCE VOLTAGE ABOVE A PREDETERMINED VOLTAGE MAGNITUDE AND ACTUATED DEPENDENTLY OF THE MAGNITUDE OF SAID SOURCE VOLTAGE BELOW SAID PREDETERMINED VOLTAGE MAGNITUDE, AND CONTROL MEANS OPERABLE IN RESPONSE TO A PRESELECTED CHANGE IN THE MAGNITUDE OF SAID SOURCE VOLTAGE BELOW SAID PREDETERMINED VOLTAGE MAGNITUDE TO EFFECT A ZERO INDICATION OF SAID INSTRUMENT.
