In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability. SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields.
A major problem facing Planet Earth is provision of an adequate supply of clean energy.
Hence, a major task for the new century will be to develop sustainable and environmentally friendly sources of energy. Wireless Power Transmission via Solar Power Satellite Projections of future energy needs over this new century show an increase by a factor of at least two and one Half, perhaps by as much as a factor of five.
All of the scenarios from reference 3 indicate continuing use of fossil sources, nuclear, and large hydro. Indeed, the projections indicate that the amount of energy derived from new renewables by will exceed that presently provided by oil and gas combined.
It will be a Herculean task to acquire this projected amount of energy. This author asserts that there are really only a few good options for meeting the additional energy needs of the new century in an environmentally acceptable way. One of the so-called new renewables on which major reliance is almost certain to be placed is solar power.
Solar power captured on the Earth is familiar to all. However, an alternative approach to exploiting solar power is to capture it in space and convey it to the Earth by wireless means. As will be described later, the power-collecting platforms would most likely operate in geosynchronous orbit where they would be illuminated 24 hours a day except for short eclipse periods around the equinoxes.
Thus, unlike systems for the terrestrial capture of solar, a space-based system would not be limited by the vagaries of the day-night cycle. Furthermore, if the transmission frequency is properly chosen, delivery of power can be carried out essentially independent of weather conditions.
Thus Space Solar Power could provide base load electricity.A low-dropout or LDO regulator is a DC linear voltage regulator that can regulate the output voltage even when the supply voltage is very close to the output voltage..
The advantages of a low dropout voltage regulator over other DC to DC regulators include the absence of switching noise (as no switching takes place), smaller device size (as neither large inductors nor transformers are needed.
