Project Description
Why attend
This course is created to provide a complete understanding of the various types of motors, variable-speed drives, transformers, generators, rectifiers and inverters, uninterruptable power systems (UPS), circuit breakers, and fuses. Once successfully completed, delegates will be able to identify, select, commission and maintain these equipment for their applications. Additionally, delegates will have sufficient information to achieve reduced capital, operating and maintenance costs along with increased efficiency.
Course Objectives
By the end of the course, participants will be able to:
Identify, select, install, operate, test, troubleshoot and maintain various types of electrical equipment such as transformers, motors, variable speed drives, generators, circuit breakers, switchgears and protective systems.
Apply diagnostic testing and inspection, advanced fault detection techniques, critical components, and common failure modes for electrical equipment.
Employ selection criteria, commissioning requirements, predictive and preventive maintenance, reliability, testing and cost estimation for electrical equipment.
Apply maintenance techniques required to minimize the operating cost and maximize the efficiency, reliability and longevity of electrical equipment.
Who should attend
This course provides an overview of all significant aspects and considerations of electrical equipment including transformers, motors, variable speed drives, generators, circuit breakers, switchgears and protective systems. It’s suitable for engineers and other technical staff who are involved in the selection, installation, operation, testing, troubleshooting or maintenance of such electrical equipment.
