Abstract

Partial discharge（PD）detection for power equipments mainly includes pulse current method

radio frequency（high frequency）method

transient ground voltage method

UHF method

chemical detection method

opticaldetection method and ultrasonic method. Among them

the PD detection method based on optical fiber sensing tech-nologies has the advantages of safety

insulation and anti-electromagnetic interference

so it is suitable to be de-signed as embedded or intrusive sensors installed on the inner or outer shell of power equipments for PD on-line mon-itoring or live detection with prospects for development. In this paper

the measurement method of PD based on opti-cal fiber sensing technologies

principle parameters and advantages and disadvantages are summarized

and thenthe detection technology of extrinsic Fabry-Perot interferometers（EFPI）optical fiber sensing is introduced. The prin-ciple and research progress of detecting PD ultrasonic signal based on EFPI fiber optic sensor and its performancetests are described in detail. The key parameters and application problems in the development of the EFPI PD fiber optic sensor are analyzed. Finally

the development trend of the EFPI PD fiber optic sensor is expected.
