Abstract

The present disclosure provides methods and apparatus for determining the presence of an electrical discharge in at least one predetermined spatial area in an electrical apparatus. According to one aspect, the method includes providing at least one sensing device configured for sensing the electrical discharge, such that the at least one sensing device is sensitive to one or more of the at least one predetermined spatial area, providing a predetermined mapping comprising data corresponding to a position, and optionally an orientation, of the at least one sensing device and a position of the at least one predetermined spatial area, sensing at least one signal using the at least one sensing device, and processing the at least one signal based on the predetermined mapping to determine the presence of the electrical discharge in at least one predetermined spatial area. According to another aspect, a detection system for detecting an electrical discharge in an electrical apparatus is provided, the system including at least one sensing device configured for sensing the electrical discharge, and a signal processing device configured for performing the method according to the above aspect.
