Why Choose this Training Course?

The primary and basic tool for troubleshooting and maintenance of an electrical installation is to understand and interpret electrical drawings and control circuits. This seminar will familiarise engineers and technicians with the various standards and practices of electrical drawings, in addition to understand the power flow and equipment installed.

Electrical symbols and designations on schematic and wiring diagrams facilitate the operations of the primary and secondary equipment. These aspects with respect to reading and tracing electrical drawing will be covered in the seminar.

This course will feature ways how to:

  • Interpret single line diagrams
  • Read the concept of the circuit’ protection and control
  • Read and trace electrical diagrams
  • Integrate diagrams during troubleshooting


What are the Goals?

By the end of this course, participants will be able to:

  • Distinguish and be familiar with electric symbols
  • Recognize and gain knowledge of electric CAD with intelligent symbols
  • Analyse electrical drawings in problem solving
  • Identify and learn more about intelligent Building Information Modeling (BIM)


Who is this Course for?

This course is suitable for a wide range of professionals; however, it will greatly benefit the following attendees:

  • Electrical Engineers
  • Maintenance Engineers and Technicians
  • Electricians
  • Electrical Supervisors
  • Professionals interested in BIM


How will this be Presented?

This course will utilize a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes audio and video power point presentation. The course is designed to have an interactive format to maximize delegate participation. Questions and answers sessions are encouraged throughout the course. The case-studies are tailored to the attendees needs and various examples from practice will be discussed in problem solving workshop sessions.
