Modeling Earth as a Rotating Solenoid Coil Greg Poole Electrical Power Engineer Pilot Hill, CA USA Abstract—Presented in this manuscript are conventional electrical engineering tools to model the earth as a rotating electrical machine. Calculations using known parameters of the earth and measured field data has resulted in new understanding of the earth’s electrical system

Benjamin Franklin’s Electric Motor

Wednesday, 04 October 2017 by

Benjamin Franklin (1706-1790) was not only a scientist, but also an engineer. More than a decade before James Watt invented his improved steam engine and launched the industrial revolution in England, Benjamin Franklin devised a working electric motor. Electrical technology in Franklin’s day consisted mainly of scientific instruments. By 1745, electrical scientists exploring the nature of

At long last, I get to blog about the paper that first piqued my interest about the research of Michael Faraday!  If you haven’t been following my Faraday posts, let me give a quick recap: Michael Faraday (1791-1867) was one of the greatest experimental physicists of all time, and the discoverer of some of the most important

DRIVES EQUIPMENT LIFE EXTENSION, MODERNIZATION, AND RETROFITTING DAVID DOLEZILEK AND GERALDO ROCHA, Schweitzer Engineering Laboratories, Inc.   I. INTRODUCTION Much of the power system equipment in use today is nearing or has passed its predicted operating life, and we are pushing equipment to increasingly higher levels to meet demands. Injuries, failed equipment, unscheduled downtime, and

Lessons for Electrical Safety and Reliability H. Landis “Lanny” Floyd, DuPont   First, it may be useful to share a bit of background on DuPont, the oldest Fortune 500 company. French immigrant Eleuthère Irénée du Pont founded the company in 1802 to make black powder to supply gunpowder and explosives used in farming, mining, and construction

Don A. Genutis, No-Outage Electrical Testing, Inc. & Neil Davies, EA Technology   Introduction Just like people, electrical assets age and deteriorate; and as with human medicine, there have been tremendous advances in recent years in the ability to diagnose in the early stages ailments suffered by assets, enabling us to keep them healthy and

BY MICHAEL SKELTON Kelvatek Background One of the most critical devices on any electricity network is the circuit breaker which can be described as the silent sentinel, standing guard over the network and only being called into action when a fault occurs. The circuit breaker needs to operate within its composite tripping time (relay trip

By Baldwin Bridger Many older installations of metal-clad switchgear are candidates for modernizing or upgrading. The interrupting duty may have grown past the interrupting capacity of the existing circuit breakers, maintenance costs may be getting out of hand, or circuit breaker parts may no longer be available.   Modernization may be accomplished by either of

Among engineers electrical engineers are the ones who specialise in the study of electricity and its applications. As the supply of power became common and commercial the need for professionals who could understand electricity and its implications arose giving birth to the specialised field of electrical engineering. As an electrical engineer there are many job
