Unbalanced current protection apparatus for parallel generator systems

Claim 1

IN AN UNBALANCED CURRENT PROTECTIVE SYSTEM FOR USE WITH A PLURALITY OF PARALLELED GENERATORS INCLUDING A FIRST GENERATOR, SIGNAL GENERATING MEANS OPERATIVELY CONNECTED TO ALL THE GENERATORS FOR PROVIDING A SIGNAL OF A FIRST PREDETERMINED AMPLITUDE WHEN THE DIFFERENCE BETWEEN THE CURRENT SUPPLIED BY SAID FIRST GENERATOR AND THE MEAN OF THE CURRENTS SUPPLIED BY ALL OF THE GENERATORS ATTAINS AT LEAST A FIRST PREDETERMINED VALUE, AND FOR GENERATING A SIGNAL OF A SECOND PREDETERMINED AMPLITUDE WHEN THE DIFFERENCE BETWEEN THE CURRENT SUPPLIED BY THE FIRST GENERATOR AND THE MEAN OF THE CURRENTS SUPPLIED BY ALL OF THE GENERATORS FALLS TO A SECOND PREDETERMINED VALUE LESS THAN THE FIRST VALUE, A UTILIZATION CIRCUIT INCLUDING A SOURCE OF ENERGIZING POTENTIAL, TRANSISTOR MEANS OPERATIVELY CONNECTED TO THE UTILIZATION CIRCUIT FOR SWITCHING THE UTILIZATION CIRCUIT BETWEEN ENERGIZED AND DEENERGIZED CONDITIONS IN ACCORDANCE WITH VARIATIONS IN THE CONDITION OF THE TRANSISTOR MEANS BETWEEN CONDUCTIVE AND NONCONDUCTIVE STATES, AND CIRCUIT MEANS INCLUDING A SEMICONDUCTOR DEVICE CONNECTING THE TRANSISTOR MEANS TO THE SIGNAL GENERATING MEANS FOR SELECTIVELY RENDERING THE TRANSISTOR MEANS CONDUCTIVE AND NON-CONDUCTIVE IN ACCORDANCE WITH VARIATIONS IN THE SIGNAL BETWEEN ONE AMPLITUDE AND THE OTHER AMPLITUDE OF SAID FIRST AND SECOND AMPLITUDE.
