An intensive professional development training course on

Electrical Drawing

Why choose this Training Course?

Electrical equipment and devices are vital in all electrical installation so as to ensure continuity and efficient operations. The primary and basic tool for troubleshooting and maintenance of an electrical installation is to understand and interpret electrical drawings and ladder diagrams.

Electrical symbols, schematic and wiring diagrams facilitate the operations of the electrical installation equipment. This course will cover all these aspects with respect to electrical blueprint reading and tracing of circuits.

This course will familiarise engineers and technicians with the various standards and practices, and help to understand the power flow and equipment installed. Fitted diagrams and ladder diagrams will be presented to correlate with the electrical equipment installed. Tracing of electrical circuits with the relevant wiring diagrams will be demonstrated to ensure correct methods of troubleshooting.  

This course will highlight:

  • The interpretation and understanding of standard electrical symbols
  • The characteristics of single line diagrams
  • The importance of ladder diagrams
  • Using diagrams for circuit tracing
  • Troubleshooting electrical system using diagrams

 

What are the Goals?

At the end of this course, you will learn to:

  • Describe the various types of electrical drawings
  • Appreciate the importance of single line diagrams
  • Analyse the various electrical ladder drawings
  • Explain the operation of the electrical equipment using wiring and schematic diagrams
  • Recognise the symbols in electrical drawings

 

Who is this Training Course for?

The technicians and maintenance staff will be able to comprehend the construction, operations, function of major electrical equipment components. This will enable them to carry out effective maintenance activities.
