The synthesis of pyrene-1-butyric acid (PBA)-doped polyaniline (PANI) and its oxygen sensing properties, through fluorescence quenching, are reported. The structures of both undoped PANI (emeraldine) and PBA-doped PANI are investigated by means of Fourier Transform InfraRed (FT-IR) spectroscopy. The O2 sensing capability of the synthesized layer is demonstrated through fluorescence spectroscopy performed...
This paper presents the results of a feasibility study for installing FACTS devices in the South-Eastern part of Romanian power grid (Dobrogea a peninsular area), to increase the transfer capacity to the rest of the grid. This study assumed, on one hand, the scheduled increase in generated power in the area, mainly due to two new units in the Cernavoda nuclear power plant (1400 MW installed power)...
The paper emphasize the results of the first systematic electromagnetic field measurements performed in high and very high voltage substations belonging to the Romanian national power grid in order to face the requirements of the EU directives regarding the human exposure to the electromagnetic fields. In the first part of the paper, the experimental field measurement results from a recently rehabilitated...
The current technical condition of an equipment is best evaluated beginning with the analysis of its components. Some of the methods used for this type of diagnose are the mathematical methods implemented in the NOVA Predict software application. This paper briefly describes the main issues which led to the designing of the NOVA Predict software application, the architecture, the function, the features...
The paper presents the electric and magnetic fields distribution at steady-state operation in a very recently rehabilitated 400/220 kV voltage power station, taking into account the on-site equipments arrangement. The experimental measurement values are compared with the public and professional electromagnetic field exposure limits imposed by the EU 2004/40/EC Directive and by the local legislation...
