Low‐Frequency Oscillation Suppression of FDR Time‐Domain Diagnostic Waveforms for Cable Defects Based on Splicing Technology

High Voltage, Volume 11, Issue 3, Page 681-691, June 2026.
ABSTRACT A time domain pulse (TDP) based on the frequency domain reflectometry (FDR) method can be used to diagnose the insulation state of cable defects. However, because of the limitations of the FDR test instrument, the lack of a reflection coefficient spectrum (RCS) in the low‐frequency band (LFB) can result in low frequency oscillation in the time
