-Power quality has always been a concern of power engineers. Certainly an argument can be successfully made that most parts of power engineering have the ultimate objective to improve power quality. AC motors were widely used in industrial and domestic applications. Generally, AC motors were of two types: Induction and Synchronous motors. In motor many parameters like different load cycling, switching, working in hot weather and unbalances creates harmonics which creates major reasons for temperature rise of the motors. Due to high peak value of voltage, harmonics can weaken insulation in cables, windings and capacitors and different electronic components. Higher value of harmonics increase the motor current and decrease the power factor which will reduce the life time of the motor and increase the overall rating of all electrical equipments. Harmonics reduction of all the motors in India will save more power. Coating of windings of the motor with nano fillers will reduce the amount of harmonics in the motor. Based on the previous project works, actions were taken to use the enamel filled with various nano fillers for the coating of the windings of the different AC motors. Ball mill method was used to convert the micro particles of Al 2 O 3 , SiO 2 , TiO 2 , ZrO 2 and ZnO into nano particles. SEM, TEM and XRD were used to augment the particle size of the powder. The synthesized nano powders were mixed with the enamel by using ultrasonic vibrator. Then the enamel mixed with the nano fillers was coated to the windings of the several AC motors. Harmonics were measured in terms of various indices like THD, VHD, CHD and DIN by using Harmonic analyzer. There are many other measures and indices to describe power quality, but none is applicable in all cases and in many instances, these indices may hide more than they show. Sometimes power quality indices were used as a basis of comparison and standardization. The efficiency of the motors was increased by 5 -10 %. The thermal withstanding capacity of the motor was increased by 5º to 15º C. The harmonics of the motors were reduced by 10 -50%.

“…The definition of nano technology was given by National Nanotechnology Initiative in U.S. Nano technology deals with structures having particle size of 1 to 100nm [1][2]. Nanotechnology is the design, fabrication and use of nano structured systems and the growing, assembling of such systems mechanically, chemically or biologically to form nano scale systems and devices [3][4] …”

“…Over heating may arise due to continuous running of motor and from the failure of many system components, such as, sensors, inverter, rectifier, power supply, etc. Many researches so far have given much importance on generalized approach for thermal analysis of 3-phase induction motor [4], [5], [8]. This paper proposes a modified d-q model that discusses the effect of variation of temperature on transient behavior of Induction motor system under running condition.…”

The main objective of this paper is to study the effect of temperature variations in Induction Motor on its transient behavior. Out of the several mathematical models available for Induction Motor, d-q model is chosen for the verification of the same, due to its enormous potential. Firstly, the d-q model is restated (Without considering the Temperature Variation) and then, the same d-q model is modified by considering the temperature variation effects. The proposed model is simulated and the performance parameters of a typical induction machine, such as, Efficiency, Power Factor, slip -speed characteristics are presented and compared.
