Coursework 2 – Transformer Core at the request of Dr. D.M.Hepburn | 1. Aims & Objectives 2.1. Aim The first aim of this coursework is to use the skills developed from lab session one to create a transformer model‚ using software package MagNet. This package allows you to simulate electromagnetic fields and measure the change in flux in the designed model. The second aim hoping to be achieved during this investigation is to gain a better understanding of the design of transformers and how

Vulnerability of the Nation’s Power Grid Mark Shelton San Diego State University PA571 November 18‚ 2014 Vulnerability of the Nation’s Power Grid There are some issues that United States governments (both state and federal) take more seriously than the others. Security matters are always given priority in the United States of America because there are many disgruntled parties who would like to see the sovereignty and unity of this nation go down the drain. The most recent security concern

DEFINITION: An amplifier with two or more stages arranged in a manner that the output of one serves as the input for the next‚ while amplifying at each step. It is also called cascade amplifier. EXPLANATION: In most of the cases the gain provided by a single stage amplifier stage is insufficient. Consequently two or more amplifier stages are cascaded in order to increase the gain. Several amplifiers can be connected in a cascaded arrangement with the output of one amplifier driving the input of the

Console is the section of the imaging system that most Technologists are familiar with. It is the Primary side of the main circuit and it includes the incoming current‚ the exposure switch‚ the autotransformer and the primary winding for the step up transformer. Through the Control Console‚ the tech is able to control the x-ray tube current and the voltage so that the useful x-ray beam that reaches the patient has the right quantity‚ or the intensity of the beam and is expressed in mR/mAs‚ and the right

Most students of electricity begin their study with what is known as direct current (DC)‚ which is electricity flowing in a constant direction‚ and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with definite positive and negative terminals)‚ or the kind of charge generated by rubbing

Earth-Fault Transformer Protection Casper Labuschagne‚ Schweitzer Engineering Laboratories‚ Inc. Izak van der Merwe‚ Eskom Enterprises Abstract—Restricted earth-fault (REF) protection on a transformer is a subject for which there has been little attention and‚ compared to other types of protection‚ very little literature exists. Depending on the method of transformer earthing and fault location‚ some transformer earth faults result in only a small increase in phase current‚ which transformer differential
