Partial Discharge Detection Method of Fibre‐Composed HVDC Submarine Cable Based on φ‐OTDR and Hilbert Demodulation

open access: yesHigh Voltage, Volume 10, Issue 6, Page 1380-1389, December 2025.
ABSTRACT Partial discharge (PD) is the indicator of the insulation defect in cables. However, the pulse current method, which is widely adopted in land cables, cannot obtain PD signals of high‐voltage direct current (HVDC) submarine cables due to attenuation and installation position.
