Course description and overview
SUBSTATION MAINTENANCE I | (SSMI | #230)
4.5 DAYS | 3.2 CEUs
This course provides an overview for apprentices, technicians and engineers responsible for the maintenance and testing of industrial and utility substations. Hands-on labs are a major part of this course to help the technician locate weak or faulty components in the substation systems. Course focus is on medium voltage circuit breakers (air and vacuum), and switchgear. The course is designed to aid skilled qualified substation maintenance technicians in the safe performance of substation component preventative maintenance. This course is available in Spanish.
Learning Objectives
To receive 3.2 CEUs, participants must attend 4.5 days of class (32 contact hours) and attain a minimum average of 80% (overall grade with consist of 50% lab practice and 50% final exam). Upon completion of the course labs, participants will demonstrate that they are able to:
- Explain the configuration and function of common equipment found in a substation.
- Identify components of air, oil, vacuum circuit breaker, and metal-clad switchgear (including switchyard equipment).
-
Utilize medium voltage circuit breaker and switchgear manufacturer instruction manuals and NETA specifications to:
- Performs all required tests
- Verify measurements
- Make adjustments as required
