Electrical Equipment Inspection, Testing and Troubleshooting

Dubai, UAE
From Date: 16-Oct-2023   
To Date: 20-Oct-2023
5 days

Electrical equipment and devices are vital in all electrical installations to ensure continuity and ehicient operations. Equipment like transformers, motors, variable frequency drives, uninterruptible power supplies and batteries are today’s common components in most electrical installations. Safe operations are essential as they are protected by modern and sophisticated relays and protection devices.



Attendees will have Practical illustrations of Electrical Equipment and Control systems which will help engineers and technicians to identify, prevent and fix common faults. Beside Protection systems which are installed to prevent faults from damaging electrical plants and to initiate isolation of faulted sections to maintain continuity of supply elsewhere on the system. Recent changes in technology, together with changes in the manner in which Utilities and Industrial organizations operate, has greatly emphasized the development of integrated protection and control.


When attendees complete this course, They will be able to understand the following:


  • Understand the operations and characteristics of transformers and motors.
  • Better understand the design and functionality of variable speed drives, UPS and batteries.
  • Utilize single-line diagrams and schematics for troubleshooting.
  • Understand standard work practices plus be able to develop job plans and maintenance strategies.
