Partial discharge detection using distributed acoustic sensing at the oil-pressboard interface
Partial discharge detection using distributed acoustic sensing at the oil-pressboard interface
This paper investigates novel, initial experimentation in detecting and analysing Partial Discharge at the Oil-Pressboard interface using a continuous fibre-optic-based Distributed Acoustic Sensing (DAS) system. Discharge was successfully detected at a minimum of 223 pC despite the sample rate of DAS being lower than the spectra of acoustic emission. DAS presents multiple advantages over conventional Partial Discharge techniques including inherent localisation, immunity to electrical and magnetic noise, as well as much greater detection distances.

Abstract
This paper investigates novel, initial experimentation in detecting and analysing Partial Discharge at the Oil-Pressboard interface using a continuous fibre-optic-based Distributed Acoustic Sensing (DAS) system. Discharge was successfully detected at a minimum of 223 pC despite the sample rate of DAS being lower than the spectra of acoustic emission. DAS presents multiple advantages over conventional Partial Discharge techniques including inherent localisation, immunity to electrical and magnetic noise, as well as much greater detection distances.
