چکیده
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 comparing the simulation and test results, parameter permittivity is recalculated by considering semiconducting screen in the process of simulation and analysis of PD. After it is proved that simulation results and test results are almost similar in the laboratory, extensive simulations are performed to analyse various PD characteristics such as propagation velocity, attenuation, etc. in 60 mm 2 and 325 mm 2 CNCV cables. Authors are confident that results obtained in this paper will be used as important technical materials to detect and investigate PD generated in transmission and distribution power cables.

This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...
متن کاملPrediction of Incipient Faults in Underground Power Cables Utilizing S-Transform and Support Vector Regression
Incipient faults usually emerge from partial discharges which eventually cause insulation degradation between two insulated cable cores. Early detection of incipient faults is of particular importance because insulation defects caused by incipient faults may lead to permanent faults in underground distribution networks. This paper presents a novel approach using S-transform and support vector r...
