چکیده
Cross-linked polyethylene (XLPE) cables are widely used in the distribution and transmission networks of power systems. The insulation materials these stressed by over voltages also exposed to various environmental conditions. This leads degrade during their normal life span. Therefore, it would be advantageous for utilities acquire cable’s condition frequently operation. In this paper, experimental studies were carried out on short sections field aged as well un-aged medium voltage (MV) XLPE investigate using non-destructive diagnostic techniques such Dissipation Factor (DF), Isothermal Relaxation Current (IRC), Partial Discharge (PD) characteristics at 60Hz. From set experiments, different parameters will analyze dielectric response condition. Finally, results show how VLF dissipation factor works efficiently assess cable aging.

Insulation coordination of MV cables against lightning - induced overvoltages generated by LEMP - coupled overhead lines
-The paper deals with the stresses of cable insulations due to lightning induced overvoltages for the case of distribution networks composed by MV overhead lines and buried cables. We are here interested only in the conditional probability of the cable breakdown in absence of line flashovers, which means that flashovers along the overhead line are disregarded. We illustrate a procedure based on...
متن کاملElectric Field Investigation in MV PILC Cables with Void Defect
Abstract—Worldwide, most PILC MV underground cables in use are approaching the end of their design life; hence, failures are likely to increase. This paper studies the electric field and potential distributions within the PILC insulted cable containing common void-defect. The finite element model of the performance of the belted PILC MV underground cable is presented. The variation of the elect...
متن کاملHigh Frequency Characteristics of Medium Voltage XLPE Power Cables
The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. A cable model has therefore been worked out based upon the high frequency properties of the cable insulation and conductor systems. ...
