Multiphase voltage monitoring system

Claim 1

A SYSTEM FOR MONITORING AN A-C POWER SOURCE HAVING MULTIPLE PHASES FOR OVER- AND UNDER-VOLTAGE, SAID SYSTEM COMPRISING: A BUS; A PLURALITY OF RECTIFIERS EACH CONNECTING A RESPECTIVE PHASE OF THE POWER SUPPLY TO THE BUS FOR CONDUCTING POSITIVE PULSES OF THE POWER SUPPLY THERETO; FIRST AND SECOND RELAYS EACH HAVING A WINDING; FIRST AND SECOND VOLTAGE-RESPONSIVE CURRENT-CONTROL DEVICES EACH HAVING FIRST AND SECOND ELECTRODES BETWEEN WHICH ELECTRICAL CURRENT FLOWS WHEN THE DEVICE CONDUCTS, CURRENT FLOW BEING FROM THE FIRST TO THE SECOND ELECTRODE, AND A CONTROL ELECTRODE FOR RECEIVING A CONTROL VOLTAGE CONTROLLING CURRNET FLOW THROUGH THE DEVICE; A FIRST, SURGE-LIMITING RESISTOR HAVING FIRST AND SECOND ENDS; AN ISOLATING RECTIFIER CONNECTED BETWEEN THE FIRST RESISTOR FIRST END AND THE BUS; A FIRST CAPACITOR CONNECTED BETWEEN THE FIRST RESISTOR SECOND END AND GROUND; A FIRST LEAD CONNECTING THE FIRST CURRENT-CONTROL DEVICE FIRST ELECTRODE TO THE FIRST RESISTOR SECOND AND THROUGH THE FIRST RELAY WINDING; A SECOND RESISTOR HAVING FIRST AND SECOND ENDS, THE FIRST END BEING CONNECTED TO THE FIRST RESISTOR FIRST END; A SECOND LEAD CONNECTING THE SECOND RESISTOR SECOND END DIRECTLY TO THE RESPECTIVE SECOND ELECTRODES OF THE FIRST AND SECOND CURRENT-CONTROL DEVICES; A VOLTAGE-REGULATING DEVICE CONNECTED BETWEEN GROUND AND THE SECOND LEAD FOR MAINTAINING A SUBSTANTIALLY CONSTANT POSITIVE REFERENCE VOLTAGE THEREON; A FIRST POTENTIOMETER HAVING A RESISTANCE ELEMENT CONNECTED BETWEEN THE FIRST LEAD AND GROUND AND FURTHER HAVING A WIPER; MEANS CONNECTING THE WIPER TO THE FIRST CURRENT-CONTROL DEVICE CONTROL ELECTRODE AND INCLUDING A THIRD RESISTOR;
