Course Description and Overview

SUBSTATION MAINTENANCE II | (SSMII | #OPN231)
4.5 DAYS | 3.2 CEUs

This course is the next step after Substation I to enhance the skills needed to perform all substation tasks including a focus on common transformer configurations. It offers training on the components of power and distribution type transformers, including common insulating and cooling mediums and explains common transformer configurations.

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:

Obtain required information from a transformer nameplate
Perform needed inspections per NETA/MTS
Demonstrate and interpret results of required tests performed on transformers
Calculate temperature corrections
Summarize ASTM requirements for testing and sampling gas and oil transformers
Outline storage battery maintenance

Lab and classroom attrire

AVO Training Institute is committed to the personal safety of each participant and require long pants and ANSI rated "safety-toe" work shoes for lab activities. Lecture courses may involve a tour of a workshop area and for this reason open-toe shoes and shorts are not considered appropriate attire for the classroom.
