New Generation of DC Power Transmission Technology Using HTS Cables
High Tc superconducting (HTS) cables and their application to develop a DC power transmission system with substantial advantages have been studied. Technical analysis of the HTS DC electrical power transmission system behaviours have been carried out with the HTS DC cable technology employed and the system models built. Index Terms -High Temperature Superconductor (HTS), HTS Cable, DC Transmiss...
متن کاملThe Application of Partial Discharge Detection for the condition assessment of XLPE Power Cables
Partial discharge (PD) detection is an important means in the condition-based maintenance of high voltage apparatus including crosslinked polyethylene (XLPE) power cables. In this contribution, we introduce the recent work in Shanghai municipal electric power company on the condition-based maintenance of XLPE power cables. As to how to carry out the PD detection in different circumstances, thre...
متن کاملOn-line Partial Discharge Assessment and Monitoring of MV to EHV Cables
To effectively manage their electricity networks, owners and operators around the world have a very real need to understand the condition of their often ageing Transmission and Distribution assets. Of all the major asset classes, underground cables often have the least available condition data but at the same time have a significant impact on network performance. One of the predominant causes o...
متن کاملPartial Discharge Simulation and Analysis Based on Experiment in Underground Distribution Power Cables
This paper describes the simulation and experiment for partial discharge (PD) pulse propagation in 22.9kV CNCV power cables. To investigate the propagation characteristics of PD, experiments are carried out by injecting the PD pulse in 100m-long 60 mm 2 CNCV cable in the laboratory. The characteristics of PD are also simulated using EMTP to investigate and analyze PD in the same cable. By compa...
متن کاملOn-site Portable Partial Discharge Detection Applied to Power Cables Using HFCT and UHF methods
Partial discharge (PD) events happen inside the power cables and cable terminations with the insulation degradation. The PD detection can effectively supply the information of cable status. According to the electrical and electromagnetic emission of PD activities, high-frequency transformer (HFCT) and ultrahigh-frequency (UHF) methods are employed to detect the PD signals. Besides, a portable P...
