This electrical diagram training course helps with understanding the operation, maintenance and appropriate trouble response to power system equipment begins with a detailed knowledge of and ability to read and interpret electrical prints. This course is designed to provide the knowledge of the various types of electrical diagrams used in the industry, and to develop the skills necessary to read, draw, and interpret these diagrams. With a basic grasp on understanding electrical diagrams, technicians and engineers are able to develop a logical pattern of troubleshooting that can aid in the successful analysis of systems. This class presents a logical approach to troubleshooting electrical power systems. Resources for predicting the likelihood of equipment failure will be provided, and a basic program for clearly identifying problems. Common electrical devices and their operational requirements will be discussed. Knowing what is required for their operation, it makes easier to determine what is preventing their correct operation. Diagram analysis for troubleshooting will be practiced. Anyone who works on or near power generation, transmission, or distribution systems should attend this course. Additionally, supervisors, managers, safety personnel, and those responsible for ensuring a safe work environment should attend this course.
