This course offers guidelines and recommendations for choosing, installing, and maintaining uninterruptible power supply (UPS) systems. It covers the entire process, from determining the need for a UPS system to selecting, installing, and ensuring its ongoing maintenance. The course covers the theoretical foundations and principles of both static and rotary UPS systems, as well as the design and selection process, installation and testing procedures, operation and maintenance guidelines, rating and sizing considerations, battery management, troubleshooting techniques, handling harmonic distortions, grounding practices, checklists, and acceptance testing protocols for UPS systems.

Course Objectives:

The purpose of this course is to provide guidance for the facilities engineers in selecting, installing, and maintaining an uninterruptible power supply (UPS) system after the decision has been made to install it.

At the conclusion of the course the student will be familiar with the:

Principles and configurations of different UPS systems such as the static and rotary UPS systems.
Design and selection criteria such as the determination of the need, safety, availability and affordability of the UPS systems.
Installation and testing including the features, location and protection of UPS systems.
Test and startup and maintenance of UPS systems.
Describe the basic building blocks of UPS and high reliability power supply systems
Understand the construction and operation of the major commercial UPS systems
