摘要

This study adopts the acoustic emission (AE) method to measure partial discharges (PD) in a cast-resin dry-type transformer and proposes a waveguide atop the high-voltage winding of the transformer to improve the propagation of the PD acoustic signals occurring in winding to acoustic emission sensors used. A waveguide is proposed to improve the signals' quick attenuation and it also is a safe method for electrical equipments measurement. Finally, a waveguide is practically installed on a cast-resin dry-type transformer; the measurements and the locating of PDs' AE signals for transformer are carried out. This study demonstrates a feasible new simple, safe and economical solution for diagnosing and locating PDs in the transformer.
