THE WORKSHOP
Power supply networks are growing continuously, and their reliability is getting more important than ever. The complexity of the whole network comprises numerous components that can fail and interrupt the power supply for the end user. Equipment such as Generators, transformers, cables and motors are vital for efficient power delivery. Any fault that impairs the proper functioning of any of this equipment must be expediently identified and rectified. Incorrect decisions would result in further damage to the equipment and inevitable increase in the cost of repairs and extended downtime.
In this two-day course, the main causes of Generator, Motor, Transformer and Cable failure, types of faults that may occur, as well as the types of tests and their application in a fault-finding process will be presented.
Through a number of case studies, guidance on how to interpret the test results will be elaborated.
“This course was a game changer for me—practical, insightful, and packed with tools I now use daily to diagnose and resolve electrical faults efficiently and safely!”
– Sarah T., Electrical Engineer
