COURSE NAME:Reading Electrical Diagrams


This course can be scheduled at your convenience, to request this course please click here

-This seminar is designed to prepare electrical personnel with the ability to read and understand the electrical diagrams, recognize equipment and verify the integrity of the existing schematics. Participants will be introduced to electrical symbols, one-line and three-line electrical schematics and their content, including basic layout and legends.

-Participants will participate in practical exercises in schematic reading, diagram verification and the steps required for creating and maintaining accurate one line diagrams. Participants are encouraged to bring examples of their own facility's prints to use during practical exercises. Low, medium and high-voltage installations can be reviewed as requested by participants.


-Create a block map of the installed equipment

-Transfer the information to the one line diagram

-Verify electrical prints and make changes to existing diagrams

- Create and maintain regulatory compliant electrical diagrams In order to comply with the above-mentioned  regulations, complete and up to date electrical single line diagrams and equipment operating and control  schematics must be made available in the work place. These important documents are required to be updated as  necessary or as equipment changes or is modified and sometimes verified on an annual basis. In addition, this two-day program is designed to provide knowledge of the various types of electrical diagrams used in the industry, and to develop the skills necessary to read, draw and interpret these diagrams.
