Basic Electrical Theory - Electricity and Magnetism Electricity and magnetism run nearly everything we plug in or turn on. Although it? s something we take for granted, it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Magnetism and electricity are closely related phenomena. Electric charge is a fundamental property of matter. Matter is made up of electrons, neutrons,  more...

Basic Direct Current DC Theory Direct current or DC electricity is the continuous movement of electrons from an area of negative (-) charges to an area of positive ( ) charges. A DC circuit is necessary to allow the current or stream of electrons to flow. Such a circuit consists of a source of electrical energy (such as a battery) and a conducting wire running from the positive end of the source to the negative terminal. DC  more...

Energy Management for Motor Driven Systems Overview A common misconception within industry has been to equate an energy reduction or conservation program with the concept of turning off equipment and shutting down processes. Instead, the program of energy management challenges plant staff to produce the products or services with the absolute minimum energy consumption. The objective is to minimize energy usage through production  more...

Instrumentation and Control Temperature Pressure Flow Level and Position Indication Overview Instrumentation is the art of measuring the value of some plant parameters, for example, temperature, pressure, flow, or level to name a few, and supplying a signal that is proportional to the measured parameter. The output signals are standard signals and can then be processed by other equipment to provide indication, alarms or automatic control. This course covers five modules  more...

Fire Protection of Confinement Ventilation Systems Overview Fires in industrial and nuclear facilities have been caused by a variety of energy sources, including electrical energy and spontaneous combustion of pyrophoric metals. While fixed fire suppression systems or operator intervention have limited the size and consequences of most of these fires, some did propagate and cause significant damage and material release. In this course the  more...

Fluid Flow Fundamentals This course covers the basics of fluid flow. You will learn the difference between laminar and turbulent flow, how to calculate Reynolds Number and how to do simple piping friction loss calculations. Learn the difference between pressure head, velocity head and elevation head, which are the components that comprise the Bernoulli Equation ? the basic equation of fluid flow. Understand the  more...

Explosives Safety Overview Department of Energy (DOE) policy requires that all DOE activities be conducted in a manner that protects the safety of the public and provides a safe and healthful workplace for employees. DOE has also prescribed that all personnel be protected in any explosives operation undertaken. The level of safety provided shall be at least equivalent to that of the best industrial practice. The  more...

Engineering Symbology Prints and Drawings Drawing is the universal language of engineering. Drawings from an engineer provide a raw account of the fundamentals that will eventually go into making something useful and necessary. Engineering drawings are a formal and precise way of communicating information about the shape, size, features and precision of physical objects. The drawings of the engineer are an obvious case of making  more...
