Course Overview

This training course discusses transformer design and operation, as well as safe and proper maintenance and testing procedures on power transformers. It covers the elementary concepts of transformers including magnetism and electromagnetism, and the role of transformers in power systems, regulations, and voltages.

Transformers serve the vital function of converting voltages to meet the requirements of appliances. Incorrect use, maintenance and negligence of transformers can cause substantial losses to businesses as well as to the environment.

Therefore, this Construction, Installation and Maintenance of a Transformer course presents basic safe operational and field diagnostics of transformers with emphasis on safe construction, installation and maintenance.

Why is the maintenance of a transformer important? Transformers are fundamental components of a power distribution system, but sometimes they are the least understood. With a sound grasp on the construction, installation and maintenance of transformers, you will be able to make knowledgeable decisions about the performance and maintenance of this critical part of a power supply system.

What kind of knowledge does the ‘Construction, Installation and Maintenance of a Transformer’ course provide? This transformer training course provides a complete overview of electrical transformers found in the industry.

This course will also cover the special transformers, transformer components, materials, cooling of transformers, performance, electrical limitations and fault management.

During the course, participants will be able to understand the importance of the proper operation, protection, and management of transformers and learn how to perform transformer maintenance, routine examinations and diagnostic evaluations.

This Zoe training course will empower you with the consciousness of knowing the importance of maintenance procedures for transformers, as well as how to go about planning and carrying out its maintenance activities efficiently. The course covers basic transformers theory, its applications, and factors of consideration in its construction, maintenance and testing processes.
