Transformers & Circuit Breakers Testing & Maintenance
Course Description
Your transformer is a valuable device with many mechanical and chemical processes taking place all the time. This course combines theoretical and practical aspects of transformer design, operation, maintenance, testing, and troubleshooting. Switchgears play an important role in the distribution and control of electrical power in manufacturing or power plant and in a utility distribution system. Negligent maintenance practices can lead to power system inefficiency and loss of system reliability. Detailed knowledge on both the theory and operation of Transformers, circuit breakers are introduced. The course will develop and enhance an understanding of what is involved in the maintenance of these essential components of the power systems, through the tips and tricks learnt and developed by some of the World's pre-eminent electrical engineers.
The Training Course Will Highlight ?

This seminar is designed to update participants with the latest development of Circuit Breakers and to present some of the more common and updated aspects of low, medium and high voltage switchgear maintenance and troubleshooting. In addition to, necessary knowledge to maintain and test power transformer efficiently and safely is covered. Moreover, the course offers the participant the information necessary in helping him prevent premature failure and costly unplanned outages. The participant will learn the oil and electrical test requirements and how to interpret the test data as well as setting up a proper preventative maintenance program.

Training Objective
