Distance relaying assembly

Claim 1

A PROTECTIVE RELAYING ASSEMBLY DESIGNED TO BE ENERGIZED IN ACCORDANCE WITH THE ALTERNATING VOLTAGE AND ALTERNATING LINE CURRENT OF AN ALTERNATING CURRENT TRANSMISSION LINE FOR DISTANCE DISCRIMINATION BETWEEN FAULTS OCCURRING ON THE LINE, COMPRISING A CIRCUIT BREAKER FOR SEGREGATING PORTIONS OF THE LINE, MEANS FOR DERIVING A FIRST DIRECT VOLTAGE HAVING A MAGNITUDE DEPENDENT ON THE MAGNITUDE OF THE ALTERNATING LINE CURRENT, MEANS FOR DERIVING A SECOND DIRECT VOLTAGE HAVING A MAGNITUDE DEPENDENT ON THE MAGNITUDE OF THE ALTERNATING VOLTAGE, MEANS FOR DERIVING FROM SAID ALTERNATING CURRENT ON ALTERNATING POTENTIAL DIFFERENCE DEPENDENT ON SUCH CURRENT, MEANS FOR DERIVING A THIRD DIRECT VOLTAGE DEPENDENT ON A RESULTANT FUNCTION OF SAID ALTERNATING VOLTAGE AND SAID ALTERNATING POTENTIAL DIFFERENCE, TRANSLATING MEANS RESPONSIVE FOR OPERATION TO SAID FIRST DIRECT VOLTAGE, RESTRAINING MEANS FOR RESTRAINING OPERATION OF THE TRANSLATING MEANS IN DEPENDENCE ON SAID THIRD DIRECT VOLTAGE, A CAPACITOR UNIT, RESISTIVE CICUIT MEANS FOR ENERGIZING SAID CAPACITOR UNIT IN ACCORDANCE WITH THE FIRST DIRECT VOLTAGE TO DEVELOP A CAPACITOR VOLTAGE ACROSS THE CAPACITOR UNIT, MEANS RESPONSIVE TO AN INCREASING VALUE OF SAID FIRST DIRECT VOLTAGE FOR SUBSTANTIALLY DISCHARGING SAID CAPACITOR UNIT, AND MEANS RESPONSIVE TO A FIRST DIFFERENCE BETWEEN THE CAPCITOR VOLTAGE AND THE SECOND DIRECT VOLTAGE FOR INCREASING THE RATIO OF THE EFFECT ON SAID TRANSLATING MEANS OF THE FIRST DIRECT VOLTAGE TO THE EFFECT ON SAID TRANSLATING MEANS OF THE THIRD DIRECT VOLTAGE, SAID TRANSLATING MEANS COMPRISING TRIPPING MEANS EFFECTIVE IN RESPONSE TO OPERATION OF THE TRANSLATING MEANS FOR TRIPPING THE CIRCUIT BREAKER, AND MEANS RESPONSIVE TO A SECOND DIFFERENCE BETWEEN THE CAPACITOR VOLTAGE AND THE SECOND DIRECT VOLTAGE FOR FURTHER INCREASING SAID RATIO.
