Abstract

Electrical equipment partial discharge（PD）ultrasonic array position is a new method

which is the ultra-sonic sensor array combined with array signal processing technology. It has high reliability and can accuratelyachieve the spatial location of the PD source. The ultrasonic array elements and the array sensor assembly are de-signed and developed

an L-typed ultrasonic array sensor is assembled and a set of local ultrasonic positioning sys-tem is built. A large number of the single

double PD source localization experiments are carried out

according tothe current localization methods of PD ultrasonic array position. The results show that the L array sensor can detectthe ultrasonic signal effectively and locate the local discharge source

it meets the needs of the project.
