INTRODUCTION Over past, necessary investment for essential improvement in the electricity system, with poor price addendum has been the scenario. With this approach of investment, especially for distribution sectors, it would be like opening Pandora’s for optimal supply to the demand. Reckoning the immense potential of energy efficient and energy savings methods, Bureau of Energy Efficiency has resorted to improvement in transformer standards. Efficient technology for equipment production and their energy efficient profile should be encouraged. By reducing power losses, utility of power distribution system is enhanced. Working of distribution transformer is to supply 24*7 powers to consumers, yet remain energized. It itself utilizes no power but undergo certain inertial losses e.g. core loss, winding loss etc. because of continuous work 24*7*365 throughout the year. In China with increase in demand of electricity, the increase in production of power and reduction in its wastage have been equated sharply. Increase in harmonics current distortion results in decreased life expectancy and increased transformer losses leading to unnecessary winding loss & typical temperature rise. Thus non-linear load was reduced & the rating system called K-factor was developed [1], [2]. Numerical simulation made it necessary to design the cable optimal structure showing current distribution control with proper twist pitch selection [3]. The distribution reforms were identified as true harmonics for better financial standards in power sector and to increase efficiency. The hallmark to transcend the void between supply and demand rests in energy efficient products & sustentation of energy which is blue print for “Power for all in 2017.” With increase in harmonic distortion of a transformer, there were increase in heating losses, higher temperature; shorten insulation lifetime and insulation stress, lower productivity, low power factor, and minimum performance of the system [7]. To obstruct these problems, rated capacity of transformer which supplied non-linear load must be reduced as per standards [4]. A design of distribution transformer that was capable of withstanding the effects of harmonic load currents should be developed by a rating system called K-Factor [5]. Harmonic currents increased losses in its structure and winding while Harmonic voltage increases losses in its magnetic core [8]. Thus extra heat was having quiet deleterious effect on the shelf life of the transformer insulation. Hence excessive winding losses due to increased eddy currents caused non- sinusoidal load current leading to abnormal temperature rise. Many works of harmonic effect on power transformer loss of life have been studied [6], [9]-[12]. Improvement of energy efficient profile of distribution transformer can be achieved by many ways like by using high performance product material like steel for transformer core, i.e. improvement in the material of the core, amorphous iron produced by annealing was available and was accepted worldwide. In contrast to the conventional steel cores, core loss is 30% less in newer transformers. The way of loading and transformer size was employed for increased savings. Transformer stands at maximum efficacy at 50% load [13]. The root cause of high losses in Indian system is at the level of distribution. Hence for decrease in loss, high energy profile equipment should be put to demand. T&D losses in India are high, in the range of 20-23 percent. The ministry of power says that aggregate technical and commercial (AT & C) losses are near 50% and even higher in some states and can be reduced if following parameters can be followed: i. Zone wise data collection on basis of percentage wastage of power loss. ii. Immediate preventive steps on war level should be adopted in high loss zones so that the average percentage may be reduce. iii. Some independent patrolling bodies should be involved that can thoroughly inspect all the working as per pre planned measurements.
