UPS Systems & Battery Chargers
UPS Systems & Battery Chargers
OBJECTIVES
The course is intended to develop knowledge of the need for a UPS, types available, UPS components, batteries, generators and maintenance.
WHO SHOULD ATTEND?
This course is directed at electrical technicians, maintenance professionals and electrical engineers who would like to expand their knowledge of UPS systems.
COURSE OUTLINE
DAY 1
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.
- Introduction
- Regulations
- Critical loads
- Purpose of an Installation
- Compatibility
- Protection and Devices
- UPS or Generator
- Maintenance
DAY 2
What is a UPS?
After identifying an item of 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
DAY 3
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
DAY 4
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 a battery?
- Storage and Care
- VLRA
- Choosing a battery size
- Size and location
- Charging
- Configuration
- Battery safety
DAY 5
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
