Paperback. Condition: New. Print on Demand. This book describes a new, precision electrodynamometer which measures alternating currents from 100 to 250 amperes, at frequencies from 90 to 180 cycles and is accurate for all wave shapes. The author, an expert in the field of electrical engineering, explains that this instrument, unlike other types of ammeters, is not subject to error caused by the inductance of shunts used with the instrument, nor by eddy currents in metal parts of the balance. The author details that this instrument may be calibrated by direct currents, measured by standard shunts, a potentiometer, and a standard cell; the moving coil circuit of the electrodynamometer is connected to terminals of a shunt designed to carry alternating current. The larger shunts are submerged in an oil bath which is water cooled and stirred. This new instrument is quick in action, convenient to operate, relatively inexpensive to build, and extremely accurate, making it a valuable tool for those working in the field of electrical engineering. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. …
