Defect and Fault Diagnosis Method for Three-Phase Cross-Bonded Cables Based on High-Frequency High-Voltage Coordinated Excitation
To address severe transmission signal attenuation caused by inter-phase electromagnetic coupling in three-phase cross-bonded cables, which significantly limits the identification of insulation defects and fault types, this paper proposes a broadband impedance spectroscopy differential-frequency decoupling and defect di...
