Maintenance Scheduling for Electrical Equipment

Bijan Ghayour, P.E.


Course Outline

This 6-hour course is intended to establish recommended practice as well as to give general advice and guidance in the maintenance of electrical equipment. Specific technical details of maintenance are included in other documents which are referenced in this document.

Maintenance recommendations are based on industry standards and experience in existing facilities. However, equipment and situations vary greatly, and sound engineering and management judgment must be exercised when applying these recommendations. Other sources of information must be consulted (e.g., manufacturer's recommendations, unusual operating conditions, personal experience with the equipment, etc.) in conjunction with this course.

The course materials are based entirely on the Unified States Department of the Interior, Facilities Instructions, Standards, and Techniques Volume 4-1B.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.


Learning Objective

The purpose of this course is to provide guidance in the maintenance of electrical equipment.

At the conclusion of the course the student will be familiar with the:


Intended Audience

This course is intended for electrical engineers and maintenance personnel involved in the service, maintenance, and upgrade of electrical equipment.


Benefit to Attendees

Proper and timely maintenance of electrical equipment is the key to the reliable operation of any industrial or commercial facility. This course offers guidelines in understanding of basic maintenance philosophies such as: preventive maintenance, reliability centered maintenance, and condition based maintenance. The goal is to achieve fewer, shorter, and more predictable outages.

Traditionally, preventive maintenance (PM) has been the standard maintenance practice in most facilities. The maintenance recommendations in this course are based on a PM philosophy and should be considered as "baseline" practices to be used when managing a maintenance program.

This course also discuses the importance of the maintenance schedule and documentation, with emphasis on keeping track of equipment condition and any performed or planned maintenance.


Course Introduction

Guidance and recommendations herein are based on industry standards and experience in existing facilities. However, equipment and situations vary greatly, and sound engineering and management judgment must be exercised when applying these recommendations. All available information must be considered (e.g., manufacturer's and transformer experts' recommendations, unusual operating conditions, personal experience with the equipment, etc.) in conjunction with this course.


Course Content

This course contains specific examples, with practical emphasis on the maintenance and maintenance scheduling of electrical equipment.

You are required to study volume 4-1B, Maintenance Scheduling for Electrical Equipment, published by the Unites States Department of the Interior, Bureau of Reclamation.
