Power Quality And UPS Training

Power Quality And UPS Systems

Our 2-Day Power Quality And UPS Training course deals with both the issue of harmonics and transients in power systems and their impact on uninterruptible power supply (UPS) systems.

This two-day technical course also deals with the need for UPS systems. It then covers the relative comparisons between various UPS topologies and their modes of operation. The batteries used for UPS systems are also covered How a battery works, their maintenance, safety and testing is throughly discussed.

A solid working knowledge of the typical electrical and electronic components found within a UPS system is explained, as well as 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 throughly discussed. This will be followed by a testing and troubleshooting section. Students will be given failure scenarios where they will learn how to determine which circuit component has opened, shorted or significantly changed in value to produce the alarm condition described. The course finishes with a general discussion on UPS system testing and maintenance procedures.

This UPS system training course is designed to assist organizations to identify the many savings to be gained from proper UPS system design, application, testing and maintenance..

Some working knowledge of basic electrical engineering principles is required, although this will be revised at the beginning of the course. Real-life experience in working with batteries and UPS systems will enable the course to be placed in context.

Satisfactory completion of the two-day version of this course satisfies the requirements of the Engineering Institute of Canada for the award of 1.4 Continuing Educations Unit credits.
