High Performance of Power Cables Using Nanocomposites Insulation Materials

Improved Lead-Free Wire and Cable Insulation Performance Using Nanocomposites

Evaluation of Epoxy Nanocomposites for High Voltage Insulation

Polymeric materials containing nanometer (nm) size particles are being introduced to provide compact shapes for low and medium voltage insulation equipment. The nanocomposites may provide superior electrical performance when compared with those available currently, such as lower dielectric losses and increased dielectric strength, tracking and erosion resistance, and surface hydrophobicity. All...

High-Voltage Insulation Organic-Inorganic Nanocomposites by Plasma Polymerization

In organic-inorganic nanocomposites, interfacial regions are primarily influenced by the dispersion uniformity of nanoparticles and the strength of interfacial bonds between the nanoparticles and the polymer matrix. The insulating performance of organic-inorganic dielectric nanocomposites is highly influenced by the characteristics of interfacial regions. In this study, we prepare polyethylene ...

degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...

A Novel FEF Method for Insulation Status Monitoring of Underground Power Cables

Monitoring on underground power cables in a close-fitting manner using mobile robot can acquire more actual information about insulation status of cables. Focusing on a water tree detection module in the monitoring system, this paper proposes fringing electric field (FEF) method to detect probably formed water tree in the insulation layer. An arch substrate based interdigital FEF sensor is desi...
