Abstract
A method and system for determining the state of one or both of an electrical conductor or an associated system utilizing a non-invasive sensor and a magnetostrictive response from the current of the electrical conductor. The method includes providing a sensor assembly including a magnetostrictive resonator sensor and a signal detector. A state of one or both of the electrical conductor or the associated system is determined with the fault detector in response to a first frequency profile and a second frequency profile obtained with the magnetostrictive resonator sensor. A fault monitoring system utilizing a magnetostrictive resonator sensor is also disclosed.
