Research on Partial Discharge Localization in XLPE Cable Accessories Using Multi-Sensor Joint Detection Technology
A multi-sensor joint detection technology was proposed based on the theory of the high frequency current transformer (HFCT) method, Ultra-high frequency (UHF) method and acoustic emission (AE) method. An experimental partial discharge (PD) testing was applied on XLPE cable with artificial defect signals. The experimental results show that the multi-sensor joint detection technology will help to...
متن کاملApplication and Research of Ultrasonic Horn in Ultrasonic Ranging System
Aiming at the problem that echo signal is hard to recognize caused by ultrasonic energy’s overquick dispersion and attenuation, a kind of ultrasonic horn is designed. According to the acoustic theory analysis, the ultrasonic horn can increase its radiation energy by improving impedance matching. The ultrasonic horn can make the directivity of sound source sharper and energy more centralized bec...
متن کاملPartial Discharge Detection in Solid Dielectrics
Partial Discharge (PD) measurement and characterization provide vital information on insulation condition, different aspects of insulation ageing useful for equipment integrity verification and diagnosis. The work demonstrates standard test methods which employs capture of PD parameters with the aid of discharge detector. This paper investigates on the voltage amplitude at which PD of a specifi...
متن کاملWavelet packet denoising for online partial discharge detection in cables and its application to experimental field results
Partial discharge measurements taken online are severely corrupted by noise due to external disturbances. In this paper a powerful noise reduction technique, based on a wavelet packet denoising algorithm, is employed to isolate the signals from the noise. This methodology enables the denoising of partial discharges that are heavily corrupted by noise without assuming any a priori knowledge abou...
