Maintenance and Troubleshooting of Ups Systems (Uninterrupted Power Supply) and Battery Power Supplies Course
Introduction:
Most commercial operations will be hampered by an unexpected power outage, which may prevent a company from engaging in trade. A continuous or backup power system will be required if an organization views electrical power as essential. The required continuity will be provided by installing a UPS. However, there are issues with these installations when maintenance is required, particularly when using the bypass. Failure due to Power Quality Compatibility Issues was the original purpose for installing the UPS.
Course Objectives:
The course is intended to develop knowledge of the need for UPS, types available, UPS components, batteries, generators, and maintenance.
Who Should Attend?
This course is directed at electrical technicians, maintenance managers, and electrical engineers who would like to expand their knowledge of UPS systems.
Course Outlines:
Introduction to the Resilient System
A sudden loss of power causes disruption to any business where there is no stand-by or safety service, the course introduces the term resilience.

What is a UPS?
After identifying an item of the load is critical then there is a need to protect or back-up the supply, a UPS is a solution.
- UPS Rating
- Parallel systems
- What is available
- Maintenance by-pass
- Off-Line systems
- Redundancy
- On-Line systems
- Interactive systems
UPS Components
How does it work? A question often asked and in this module, the method of operation is examined.
- Transformer methods
- Harmonics
- Invertors
- Twelve pulse rectifier
- Phase control
- Power factor
- Six pulse rectifier
- Static switch
Batteries
Batteries are essential as an alternative store of energy providing the reserve power needed by the UPS after a mains failure. They are also dangerous especially during installation and maintenance.
- What is the battery?
- Storage and Care
- VLRA
- Choosing a battery size
- Size and location
- Charging
- Configuration
- Battery safety
Generators and Site Planning
If a power failure exceeds the reserve battery capacity the system will fail but using a generator will ensure continuous power. Planning the site and considering the load will ensure a successful installation and careful maintenance planning will ensure reliability.
- Do I need a Generator?
- Environmental Constraints
- Mains failure
- Monitoring power
- UPS Compatibility
- Installing the UPS
- Generator size considerations
- Maintaining the UPS
