Substation Drawings and Applications – Physical
This course describes how to integrate information from a variety of sources into original drawings which are used during the installation of high voltage circuit breakers. Participants utilize cut sheets provided by circuit breaker, disconnect switch and structure manufacturers to develop plan and section views as well as cable and raceway drawings.
Who Should Attend
Project managers, engineers, supervisors, designers, technicians, analysts, consultants, managers and others who need to utilize physical electrical drawings as part of their assigned duties.
Benefits and Learning Outcomes
Upon completing this course, participants understand the details that need to be considered when installing high voltage circuit breakers in open air substations. This includes circuit breaker and disconnect switch orientation, working clearance, electric clearance and bushing designations.
After discussing sample drawings, reference documents and “industry best” work practices, participants use a scope of work document to develop the following:
- Material list
- General arrangement
- Foundation plan
- North-south section view
- East-west section view
- Grounding plan
- Conduit and raceway layout
Participants create a drawing list and exchange drawings to compare and peer-review work products. Participants perform operations, maintenance and constructability reviews to assure that final work products effectively present essential details.
Note: Substation drawings are custom products that reflect the preference of the individual who prepared the drawings. Participants are given copies of preliminary drawings that include 20% of the essential details and sample copies of similar drawings. Participants use preliminary drawings to create IFC (Issued for Construction) drawings that are peer-reviewed for accuracy and completeness.
