A Comprehensive Review on Impact of Machining Parameters on MRR and SR
No full textThe electrical discharge machining (EDM) process is a non-conventional machining process that is utilized to create high caliber and exact dimension items. This machining (EDM) is used to machine the smallest to complex geometrical shapes. Thermal energy helps to evaporate and melt the material from a work piece. Circulation of dielectric fluid removes out the debris from working zone and maintains the stability of machining process. EDM process is generally used for machining with different applications such as automobile, aircraft, aerospace, tools and dies, etc. This paper provides a review on the effect of different input parameters of EDM such as current, pulse off time, pulse on time, etc. on material removal rate (MRR) and surface roughness (SR)
A Comparative Review on ALU using CMOS and GDI techniques for Power Dissipation and Propagation Delay
No full textArithmetic and Logic Circuits are to be designed with less power, compact size, less propagation delay in this fast growing era of technology. Arithmetic operations are indispensable and the basic functions for any high speed low power applications like digital signal processing, microprocessors, image processing, etc. Consumption of power is the major issue in designing these circuits. Also the number of transistors required is also the one of the issues in designing the circuits. To minimize the transistors required in designing the circuits and to reduce the power consumption of the circuits, the authors have referred some techniques to overcome these problems in this paper. By reviewing all these techniques, the authors try to implement the GDI technique to reduce the power consumption and transistors count or the area required to design the circuits
Study about Power Filters in Power System Quality and Stability Enhancement
No full textThe excessive power electronics devices in the distribution systems have evolved the problem of power quality. Arc Furnaces, Variable Frequency Drives (VFD), Computer power supplies play a major role in the deterioration in the quality power by injecting harmonics in the utility supply source. Extensive use of non-linear loads leads to a multitude of unwanted harmonics in the operation of the electrical system. Of these, the harmonics of current and voltage are the most significant. in this paper presented is the power quality and the Shunt Active Power Filter and the description of the Harmonics and Its Effects

Study on Transmission Line and Associated Varying Parameters, Devices and Control Algorithms
No full textThe transmission line is the most important part of the electricity network. The need for electricity and its affiliations have increased exponentially in modern times and the main task of a transmission line is to transmit electricity from the area of ??origin to the distribution network. The explosion between limited production and huge demands placed more emphasis on reducing power losses. Losses like transmission loss and also conjecture factors as like as physical losses to various technical losses, another reason is that reactive power and voltage difference in the long distance transmission line are of great importance. In essence, fault analysis is a very important topic in network technology in order to eliminate errors in a short time and restore the electrical network as quickly as possible with minimal interruptions. However, detecting errors that interrupt the transmission line is in itself a difficult task to look for errors and improve system reliability. The transmission line is vulnerable to all parameters that connect the entire electrical network. A review of the transmission and associated equipment was described in this study. And it explains the classification and fault detection scheme. This document provides an overview of transmission line failure detection
