摘要：For secure power transmission and reliable power distribution,it is necessary to detect power equipment failure immediately when it occurs.In order to properly accomplish the failure detection,we pay attention to the measurement of a partial discharge noise at the electrical power equipment because the partial discharge should be observed before the failure due to insulation deterioration.In this paper,we developed an arrival direction detection system with a two antennas for the partial discharge noise.In the developed system,the twodimensional angle of arrival（AOA） of the partial discharge noise was estimated based on the phase difference between two received signals.We experimentally evaluated the accuracy of the AOA detection in two types of situations:anechoic chamber and outdoor environment,for an amplitude modulated signal as the first step to simulate a partial noise.The experimental results demonstrated that the detection error of AOA was below10 degrees.
