The problem of energy accessibility and production on Mars is one of the three main challenges for the upcoming colonisation of the red planet. The energetic potential on its turn… Read more
Engineers at MIT (Massachusetts Institute of Technology) have figured out a way to deal with virus that is better than just killing them: they’re putting them to work. The researchers… Read more
Galloping climate change and dwindling supplies of fossil fuels are driving ever-greater interest in renewable energy. As a result, wind energy is booming worldwide. Not since the heyday of the… Read more
Written by Ray Salemi State machines are a foundation of digital design. Eventually we all reach the point where we need to control our digital algorithm, and we almost always… Read more
Compressed SF6 gas used in MV and HV switchgears as an insulating medium has led to the development of compact gas-insulated substation (CIS) technology (figure 1). GIS , having many… Read more
Recommended minimum illuminances (E) for typical interior lighting tasks. The illuminances are aimed at a lighting level appropriate to the specific visual tasks to be performed in the space or… Read more
A load break switch is a disconnect switch that has been designed to provide making or breaking of specified currents. This is accomplished by addition of equipment that increases the… Read more
A number of electrical apparatus installed in substations are filled with oil that provides the necessary insulation characteristics and assures their required performance. Electrical faults in this power equipment can… Read more
In large, modern AC power systems, the transmission and distribution systems function to deliver bulk power from generating sources to users at the load centers. Transmission systems generally include generation… Read more
The vast majority of electrical utility substations designed to transform transmission voltages to distribution class voltages employ an open-air design. The configurations may vary, but usually consist of equipment that… Read more
