In this country, as well as in most other developed countries, we have gotten used to the conveniences and comforts that electricity provides. Much, if not most, of our modern technology is heavily, or totally dependent on electricity as its energy source. This interactive online course covers the basics of Standby Electrical Power Systems. These are power systems which remain in a standby mode (meaning “ready to go”) just-in-case the utility-supplied electricity to a campus, a building, or an individual room fails, for whatever reason.

Learning Objectives

By the end of this course, you will be able to:

• Describe the basic purpose and function of an ATS (automatic transfer switch)
• Identify the two major categories of widely used standby power systems
• Describe the manual or automatic maintenance and inspection requirement for the standby generator and the transfer switch
• Describe the functionality of an engine block heater
• Identify the ATS steps of manually switching from the utility-supplied power to generated power

An electronic power supply is a device, or a group of devices, that converts normal generated alternating current (AC) power into power that is suitable for electronic equipment. An electronic power supply typically includes some or all of the following types of devices: transformers, rectifiers, filters, regulators, voltage multipliers, and voltage dividers. The components of a specific power supply are directly related to the requirements of the electronic equipment being served.

Learning Objectives

• Describe a power supply and its components.
• Explain the function of a transformer and how it operates.
• Explain rectifier circuit operations.
• Explain filter circuit operation
• Explain regulator circuits and operations.
• Explain the operation of a voltage multiplier circuit and a voltage divider circuit.

Rectifiers are essential for the operation of everyday electronics. However, problems with these rectifiers can arise, and it is just as essential to give these problems immediate attention. This course will serve as a brief discussion on how to troubleshoot both half-wave and full-wave rectifiers.

Learning Objectives

• Explain a troubleshooting process to identify a power supply half-wave rectifier circuit problem.
• Explain a troubleshooting process to identify a power supply full-wave rectifier circuit problem.
