What is the paper about?

Partial discharge monitoring and diagnostic of the insulation of HV assets requires precise measurment. This paper presents a novel acoustic PD monitoring system developed by Optics11.

Thanks to its unique fiber optic technology, this system offers several advantages over classic PD sensing solutions that will be discussed in this paper. Optics11’s solution was tested in a one to one comparison with a HFCT sensor in detecting internal PD’s in a medium voltage joint. The Optics11 system was able to successfully detect PD events down to 70 pC with an SNR of 25 dB, with potential to detect PD events down to a few pC’s in instances with lower inception PD levels.

What is OptiFender monitoring system?
