Electronic Tap-Changers as Custom Power Tools

Abstract

Electrical power generator units supply small and large electrical energy consumers in the most economical way, as such that the delivered electrical energy has acceptable reliability and quality (Billinton and Allan IEE J Electro Power 30(3):231-236, 1984). But for many decades, electricity suppliers had concentrated on generation, transmission and distribution of electrical energy to the consumers. This was while reliability and quality were not taken into account seriously (Bollen Understanding power quality problems. IEEE Press Series on Power Engineering, 2000). The reason was that those days lighting was the most important load of consumers. Of course electrical motors loads have been gradually grown as major loads of the power systems. However, consumers could wait hours for the re-connection of electricity. © Springer-Verlag Berlin Heidelberg 2011.
