Power electronics based controllers used in distribution systems are called custom power devices. These devices have been proved to be quite effective in power quality enhancement. They may be of series, shunt and series-shunt or series-series type – depending upon their connection in the circuit...

Due to use of better grade materials and optimum design, sudden failures are reduced along with lower cost of maintenance, leading to increased life expectancy. These benefits add up and balance against the inevitable increase in purchase cost – as additional copper in the windings and better materials in the core will be used in the manufacture of high efficiency transformers...

Electrical power is transmitted through the transmission systems from the central generating stations to the end users using a series of distribution transformers and lines. From around 1990, there has been a growing interest in connecting generations directly to the distribution system, known as Distributed Generation (DG) or Distributed Energy Resources (DER). In some countries, a strict definition of distributed generation is made, based either on the rating of the plant or on the voltage level to which it is connected to the grid. However, these definitions usually follow technical documents.
