UPS Systems and Battery Maintenance

Who Should Attend?

Supervisors, electricians, technicians and others who need an understanding of the principles and techniques of Uninterruptible Power Supply (UPS) and Battery testing and maintenance.

Course Description:

The course begins with a discussion of the need for UPS systems with comparisons between various UPS topologies and their modes of operation. Battery fundamentals are discussed next including operation, maintenance, safety, and testing. A solid working knowledge of the typical electrical components found within a UPS system is developed before exploring how AC is converted to DC and then inverting DC back to AC.

When all of the above elements of a UPS are understood, a theoretical rectifier and inverter feedback loop are thoroughly discussed. This will be followed by a trouble shooting exercise. The students are given failure scenarios where they work in groups to find which circuit component has opened, shorted or significantly changed in value to produce the alarm condition described. The course finale includes a general discussion on UPS system troubleshooting.
