Popis:	Ultra high frequency (UHF) partial discharge (PD) detection approaches take advantages of strong anti-interference ability, and have been considered as a promising technology for online monitoring PD signals. This paper presents a meander antenna with wide frequency band and small size for UHF PD detection in power transformers. The optimal geometric parameters of the meander antenna were obtained through the parametric investigation. A prototype of the proposed antenna was fabricated. Actual PD experiments were carried out for typical artificial insulation defect models while the antenna was used for PD measurements. The experimental results show that the proposed meander antenna is suitable and effective for UHF online monitoring of PDs in transformers.
