ELECTRICAL ENCYCLOPEDIA

Introduction to Electric Circuits Ebook   As in earlier editions, the central theme of Introduction to Electric Circuits, 8th Edition, is the concept that electric circuits are a part of the basic fabric of modern technology. Given this theme, this book endeavors to show how the analysis and design of electric circuits are inseparably intertwined with the ability of the engineer to design complex electronic, communication, computer, and control systems as well as consumer . continue.. Electric Circuits: Student Study Pack Ebook   Problem solving is fundamental to the study of circuit analysis. This resource teaches students techniques for solving problems presented in Nilsson & Riedel's Electric Circuits, 8e but was designed as a supplement to stand on its own as an instructional unit. Organized by concepts, this is a valuable problem-solving resource for all levels of students and includes step-by-step problem-solving techniques, additional examples, and practic...

Welcome to Transmission-line hub!   One of the most useful forms of energy ever utilized is in the form of electricity. It is a primary if not the sole contributor in the advent on human history and civilization. It is almost impossible to imagine living today without electric power. Without it, you won't be reading this blog, since nothing will power your computer. continue.. Basic Components of Overhead Power Lines   The most common way method of transmitting power is through overhead power lines. It is relatively less costly, visible detection of faults, repair and maintenance is easier compared to underground system. The following are the basic components of an overhead power line (click on links to see pic):. continue.. Uses of the single-line diagram   The single-line diagram may be used in a number of important ways in operating and maintaining an industrial or commercial power distribution system. Frequently, the single-line diagram, with all of the listed ...

Basic Steps in Solving Power Quality Problems   Steps in solving power quality problems usually include interaction between the utility supply system and the customer facility. This is because power quality problems have different causes that can be traced from both the utility and the end-users. Consequently, different solutions are available in order to improve the power quality and equipment performance. The problem solving process should also consider whether the assessment involves an existing power quality problem or one that could result from a new design or from proposed alterations to the system. continue.. Power Quality Basics:Voltage Swell   Voltage Swell is defined by IEEE 1159 as the increase in the RMS voltage level to 110% - 180% of nominal, at the power frequency for durations of ½ cycle to one (1) minute. It is classified as a short duration voltage variation phenomena, which is one of the general categories of power quality problems mentioned in the second...

What is powersystemsloss all about?    System's loss reduction is now one of the most growing trends in every electric distribution utility. Primarily triggered by economics and regulation concerns, Transmission and Distribution companies now sets more focus in reducing losses and become as an efficient utility as possible in delivering power. Information found in this site will be very useful not only to electrical practitioners but it is also our goal to help students better understand the actual world. Thank you and lets all enjoy learning! continue..   Back to basic    n case you don't know, the power we get from our household electrical outlet didn't just appear in the thin air. It may appear that it is coming out from our walls but we all know that looks can be deceiving. Before reaching our respective homes, electric current passes through miles and miles of c...

LED flasher circuit http://www.simple-electronics.com/2010/11/led-flasher-circuit-using-555-ic.html   This project is a flashing led circuit powered by 555 timer IC.This flasher circuit is composed of two versions, the simple led flasher  that uses only two LED, and big flasher that consists 20  LEDs. Simple LED Flasher circuit is powered from a 6V to 12V battery and delivers a current of about 20mA to LED. The frequency of the flashing on both LED is controlled by 100K potentiometer connected between the discharge and trigger pin of 555 timer IC. The rate of flash ranges from 1blink per 2 seconds up to 10 flashes per sec.  continue..   12V to 5V DC converter using 7805 regulator IC http://www.simple-electronics.com/2009/11/12v-to-5v-dc-converter-using-7805.html   This simple converter project uses 7805 IC to convert 12V dc from a battery to 5V DC. This converter also can be made even only one component, the 7805 regulator. Converter can produce a ma...
