Abstract

A partial discharge detection apparatus, includes: a support structure and a first antenna configured to receive electromagnetic signals at least partially associated with partial discharges of an electric object and generate a first electrical signal, the first antenna having a first receiving effective area for first receiving directions and a second antenna configured to receive electromagnetic noise signals and generate a second electrical signal, the first and second antennas being arranged to cause the second antenna to have a second receiving effective area for the first receiving directions smaller than the first receiving effective area. The apparatus further includes a first processing module configured to generate from the first and second electrical signals a difference electrical signal representing a difference between the first electrical signal and the second electrical signal.
