  • Optimizing transformer exciting current and loss test results by dynamically managing core magnetic state
    Patent number: 12094651
    Abstract: Disclosed herein are systems and methods for optimizing transformer exciting current and loss test results by dynamically managing core magnetic state. In an exemplary embodiment, a method includes injecting a direct current (DC) offset voltage; adjusting at least one of a polarity and a magnitude of the DC offset voltage while monitoring a test current for one or more criteria; and bypassing a source of the DC offset voltage when the test current has satisfied the one or more criteria, whereby residual magnetism, if any, of a core of the transformer is minimized.
    Type: Grant
