Electric power quality and efficiency of power supply

21st IEEE Convention of the Electrical and Electronic Engineers in Israel. Proceedings (Cat. No.00EX377), 2002
The quality of power supply depends on the quality of electrical energy, and also on the frequency and duration of probable interruptions in power supply, which increase with decrease of electric power quality (EPQ). The problem of EPQ has an important economic and technical significance for all countries, including Israel.

A wind-operated electric power supply

Electrical Engineering, 1957
A new type of wind-operated power supply having only one moving part is described. Tests of more than three years' duration show that it may be operated without servicing under a wide range of weather conditions.

Power Politics: Electricity Supply in Europe

2007
AbstractElectricity offers another case to refine and test the book's arguments about the role of policy forms of internationalisation. Its economic institutions were historically similar to telecommunications and securities trading but internationalisation has differed: transnational technological and economic developments were limited over the period

Nigerian electric power supply quality improvement

Scientia Africana, 2017
Improving the quality of the Nigeria electric power supply means improving voltage, transient and frequency stabilities. Power system voltages are controlled by the reactive power component of the power supply; hence voltage and transient stabilities can be improved by using reactive power compensators to either supply or absorb reactive power from the
