Electrical Systems

Possibly the most important source of power that we rely on is electricity. Electricity powers our computers, drives the machines tools in a manufacturing shop, and lights the facility. To maintain all this electrical equipment, employees must understand the fundamentals of electricity and the components used to generate, control, and store it.



These classes explain the key concepts of electrical maintenance for individuals in the manufacturing environment. The class content first addresses the main principles, units of measurement, and components used in simple electrical circuits. Intermediate-level classes address methods for calculating electrical units, the principles of alternating current, and specific comparisons regarding the selection of electrical components.

OnlineMaintenance550Electrical Systems420010 Electrical Units 101 “Electrical Units” provides a foundational overview of electricity, including fundamental measures and terminology used to discuss electricity. Electricity is the flow of electrons, which are negatively charged particles. The amount of valence electrons in an atom determines how well it allows electricity to flow. There are two types of electricity, alternating current and direct current, but both flow from negative to positive. Current is measured by certain terms, including amperage, voltage, resistance, and wattage. Ohm’s Law and Watt’s Law describe the relationships between these values in a circuit.

When working with electrical systems, knowing how electricity flows and what different terms mean is very important. After taking this class, users should be familiar with the fundamentals of electricity and the vocabulary used to describe it. This enables users to build an understanding of more advanced electrical concepts and discuss them with the correct terminology.

OnlineMaintenance550Electrical Systems420110 Introduction to Circuits 201 “Introduction to Circuits” provides a foundational overview of electrical circuitry. Whether wired in series, parallel, or a combination of the two, all circuits consist of a source, path, control, and load. Each of these components serves a purpose, and many circuits have extra components to prevent safety hazards and damage. Visual representations of circuits, such as schematic diagrams, use symbols of these components to illustrate the circuit’s layout. This method makes it easier to understand circuits and the rules that describe how they function, such as Kirchhoff’s Laws.

Understanding how circuits work is essential when working with electricity. This includes being familiar with circuit components, circuit diagrams, and the rules that govern circuits, which serves as the basis for understanding advanced electrical topics. Without the foundational information presented in this class, users would not be prepared to study more complex aspects of electrical systems.

OnlineMaintenance550Electrical Systems420115 Introduction to Magnetism 211 “Introduction to Magnetism” provides a thorough overview of magnetism and how it relates to electricity. Magnetism is a force of attraction and repulsion that occurs when the molecules in a material align. Materials become magnetized when they are exposed to a magnetic field. Materials can be demagnetized with heat, vibration, or a magnetic field generated by alternating current. Magnets have two different poles, like the earth. Magnetic forces exit the north pole of a magnet and are attracted to the south pole. These forces, or lines of flux, are essential for producing electricity with magnetic induction.

Electricity and magnetism are closely related. Magnetism is used to create electricity, and electricity is used to create magnetism. Most of the world’s electricity comes from magnetic induction, and electric motors also operate on magnetic induction. Understanding how these and other magnetic devices work requires familiarity with magnetism and its relationship to electricit
