MOTOR SINGLE PHASING BASIC DEFINITION AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on May 9, 2012A 3-phase motor can be subjected to a situation referred to as “single phasing.” Single phasing means one phase is open—somewhere. The current values shown in the figures are for a “pure” single phasing condition with one motor only in...



FUEL CELLS BASIC PRINCIPLE AND TUTORIALS by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Feb 1, 2012BASIC PRINCIPLE OF FUEL CELLS How Fuel Cell Works? The fuel cell works by processing a hydrogen-rich fuel—usually natural gas or methanol—into hydrogen, which, when combined with oxygen, produces electricity and water. This is the reverse ele...
