Abstract:
A method and apparatus of performing power line sensing is presented. The method and apparatus includes a three-axial vector magnetic sensor for detecting a magnetic field radiated from a power line. An active isolation system is used to determine the effects of noise and other magnetic fields on the three-axial vector magnetic sensor. Power line status information is then determined from data received from the three-axial vector magnetic sensor and the active isolation system.
