NON-CONTACT ARC DETECTION APPARATUS AND METHOD

摘要

The present invention relates to a non-contact arc detection, recognition, and warning apparatus for the detection of arcing in an electrical system. The apparatus includes an electric field detector having first and second electric field sensors adapted to sense electric fields; a magnetic field detector having a multi-axis magnetic field sensor adapted to detect a magnetic field; and a digital signal processor. The digital signal processor compares and enhances signals obtained from the electric field detector and the magnetic field detector and creates a response to alert a user of the presence of arcing.
