JFET_V1_N2_A1 C. Thanga Raj Journal on Future Engineering and Technology 2230 – 7184 1 2 13 17 Energy efficiency, Induction motor, Power electronics, voltage control The Indian power sector more than tripled its installed capacity from 30 GW in 1981 to over 110 GW in 2003-04; however the country is still plagued by severe peaking and energy shortages. These shortages are exacerbated by inefficiencies in power generation, distribution and end use system. The efficiencies in the end use system are due to irrational tariffs, technological obsolescence of industrial equipment, and lack of awareness, a nascent energy service industry and inadequate policy drivers. This paper presents an analysis of partial loaded induction motor with energy efficiency. Attributes under investigations include, 1) effect of using oversize induction motor 2) voltage regulators 3) experimental study in 1 HP motor 4) case study at 55 kW Motor November 2005 - January 2006 Copyright © 2006 i-manager publications.
