Ethylene-Propylene-Diene Monomer (EPDM) insulators are used as indoor and outdoor insulators for high and medium voltage applications. This paper presents detailed investigations of the electrical properties of EPDM cable terminations. The effects of different environmental conditions (Dry and Wet at different salinities) under the effects of various levels of the ultraviolet (UV) radiation on ...

Power transmission covering long-distances has shifted from overhead high voltage cables to underground power cable systems due numerous failures under severe weather conditions and electromagnetic pollution. The are limited by the melting point of insulator around conductor, which depends on surrounding soils’ heat transfer capacity or thermal conductivity. In past, numerical theoretical studi...

Cable bacteria induce long-distance electron transport in the seafloor and can exert a powerful control on the elemental cycling in marine sediments by creating extreme excursions in porewater pH. Yet, the natural distribution of cable bacteria is still largely unknown, and so their role in coastal biogeochemical cycling remains poorly quantified. Here we show that cable bacteria can be abundan...

Abstract. Sufficient thermal-electromagnetic stability against external heat sources is an essential design criterion for superconducting Rutherford cables, especially if operated close to the critical current. Due to the complex phenomena contributing to stability such as helium cooling, inter-strand current and heat transfer, its level is difficult to quantify. In order to improve our underst...

We are developing a novel high-efficiency, high-temperature steam electrolyzer. Although water or steam electrolysis is well known to be one of the cleanest ways to produce hydrogen, widespread utilization is hindered by high operational costs because of high electricity consumption. To decrease the electrical power input requirements in electrolysis, our approach uses natural gas as an anode d...

Based upon a framework of time-frequency analysis, a path towards systematic and comprehensive implementation of condition based maintenance (CBM), or maintenance only upon evidence of need, is outlined for both electrical and mechanical systems. Specifically, metrics are proposed for helicopter drivetrain systems and electrical cable. Using principles of time-frequency analysis, metrics for he...

Despite its status as a nature reserve, Wolong Nature Reserve (China) has experienced continued loss of giant panda habitat due to human activities such as fuelwood collection. Electricity, though available throughout Wolong, has not replaced fuelwood as an energy source. We used stated preference data obtained from in-person interviews to estimate a random utility model of the choice of adopti...
