Maintenance in transmission networks is an economical way to reduce upgrading network costs without decreasing its reliability. Hence, new studies regarding transmission expansion planning (TEP) must take into account the ...

This study presents a data analysis of the lead-acid vented batteries deterioration, that make up the emergency power systems of the stations’ priority loads of São Paulo’s Subway Line 1 - Blue. The objective is a definition ...

This project considers the adequate way to perform maintenance for grounding systems, in the subtransmission line at 69 kV of Sacha- Orellana. The maintenance manual, object of this project, details the procedures, personal, ...

The economic performance of a railroad is a reflection of the quality of the railway track and the frequency of maintenance required. Maintenance of the permanent road has a significant cost, especially when rail replacement ...

After many years of stability, the global automotive market undergoes transformations. Traditional manufacturers suffer financial crises in saturated markets, Asian manufacturers expand their market share, the BRICS ...

The maintenance organization is the first step towards a solid structuring of the sector. With well-defined processes and codes, the flaws are evident and can be studied so that the necessary measures are taken to achieve ...

Thyristor-based onload tap-changing ac voltage stabilizers are cheap and robust. They have replaced most mechanical tap-changers in low voltage applications from 300 VA to 300 M. Nevertheless, this replacement hardily ...

In the vast majority of cases, when consumers think of an electrical power system, the importance that electrical insulators play in the process of transmission and distribution of energy is often overlooked. However, ...

The WNT signaling system plays an important but paradoxical role in the regulation of pluripotency. In the cow, IWR-1, which inhibits canonical WNT activation and has WNT-independentactions, promotes the derivation of ...

En el desarrollo de este estudio, se tiene como objetivo la importancia del mantenimiento preventivo versus el mantenimiento correctivo, para reducir los altos costos en reparaciones no planificadas. Los beneficios de ...
