Method for transforming and testing of electrical coils in an inductive device

Abstract

Abstract AN INDUCTIVE DEVICE, FOR INSTANCE A MAGNETIC CORE HAVING ELECTRICAL COILS OR WINDINGS CARRIED IN SLOTS, FOR ARRANGEMENT IN A LOAD CIRCUIT. AT LEAST ONE PULSE OF ELECTRICAL ENERGY IS SELECTIVELY APPLIED TO THE LOAD CIRCUIT FROM AN ELECTRICAL ENERGY SUPPLY CIRCUIT FOR TRANSFORMING THE COILS FROM ONE CONFIGURATION INTO ANOTHER. A WINDING QUALITY TESTING CIRCUIT, SUCH AS ONE TO PERFORM A HIGH POTENTIAL TEST, IS THEN SELECTIVELY CONNECTED TO THE LOAD CIRCUIT FOR AUTOMATICALLY CONDUCTING THE TEST ON THE INDUCTIVE DEVICE WHILE IT IS STILL ARRANGED IN THE LOAD CIRCUIT TO DETERMINE THE QUALITY OF THE DEVICE, SUCH AS DETECTION OF WINDING-TO-GROUND FALUTS. IN THE EVENT THAT A WINDING DEFECT IS DETECTED, FURTHER TRANSFORMATION OF THE ELECTRICAL COILS IS DISCONTINUED. THIS INTERRUPTION PERMITS REPAIR, IF POSSIBLE, OF THE COIL AND CORE AT AN EARLY STAGE IN THE COIL TRANSFORMATION. ON THE OTHER HAND, WHERE THE QUALITY HAS BEEN FOUND TO BE SATISFACTORY, ANOTHER PULSE OF ELECTRICAL ENERGY MAY BE SELECTIVELY APPLIED TO THE INDUCTIVE DEVICE IF DESIRED TO EFFECT THE DESIRED TRANSFORMATION, WITH A SECOND WINDING QUALITY TEST BEING PERFORMED ON THE COIL THEREAFTER BY ONCE AGAIN CONNECTING THE WINDING QUALITY TESTING CIRCUIT TO THE LOAD CIRCUIT.
