ELECTRICAL STRESS CONCENTRATION AT THE TERMINALS OF M.V. & H.V. XLPE CABLES

High 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. ...

Short Literature Survey on the Reliability of Ehv Xlpe Cables

An Accelerated Wet Ageing Test on Meduim Voltage Xlpe Cables

The failure of medium voltage (MV) cables in North Queensland has led Ergon Energy to consider the relative economics of refurbishment or replacement. In order to provide data to inform decision making, an accelerated ageing program has been designed to investigate the ageing of new, field aged, and refurbished cables. This paper describes the considerations affecting the design of the ageing e...

Remote control of HV stations and MV substations in Milan

Aem Elettricità SpA Aem Elettricità is part of Aem Group, a former multi-service power utility located in Milan, Italy. Following the market evolution, Aem Group is undergoing a period of deep changes, too. The major one derive from the achievement of the city distribution network previously owned by ENEL. Indeed, AEM and ENEL have shared the distribution in Milan since 1962. Now, according to ...

تخمین عمر عایقی کابل های فشار قوی XLPE تحت تنش های حرارتی، الکتریکی و همزمان

The aging of insulating materials can be estimated by an electrical breakdown occurring in electrical components so that the relationship between lifetime, failure probability and reliability of electrical components may be studied using the life models in high voltage cables networks. In last decades with attention to higher features as electrical, thermal, mechanical characteristic, widely cr...
