Maintenance Basics

Basic Electricity Review


Modern Industrial plants contain a great deal of electrical equipment that needs to be maintained and repaired. To perform electrical maintenance tasks correctly and efficiently, electricians and electrical maintenance personnel must have (1) a basic understanding of the fundamentals of electrical theory; (2) a specific knowledge of the way electrical devices operate; and (3) practical hands-on experience.

Alternating Current Fundamentals


Most of the electrical equipment used today operates on alternating current (AC). The purpose of this training unit is to review significant terms, concepts, and principles associated with alternating current.

Electrical Safety


This course is designed to teach trainees about electrical hazards and about the protective devices and safety practices that can help prevent injuries and equipment damage on the job. The course discusses safety hazards and protective devices. It also presents a step-by-step explanation of safety practices associated with switching, tagging, testing, and protective grounding.

Introduction to Metering


This course is designed to present an overview of kilowatt-hour meters and meter operation. Although the program is intended to be introductory, several devices, procedures, and concepts presented assume a familiarity with basic electrical theory and distribution systems. Students without this prior training may require additional explanation or instruction.

Safety in Meter Work


This course covers the hazards and basic safety guidelines associated with meter work and emphasizes working safely near energized equipment, using caution when approaching potentially hazardous conditions, and using protective equipment properly.

Overhead - De-energized

Service Installation


This course describes basic procedures for installing and connecting services. The course describes common types of service connectors, and demonstrates the basic steps involved in making a service connection. The course also demonstrates procedures for installing both overhead and underground residential services. This course describes three types of voltage tests that should be performed before making service connections. The course also describes procedures involved in installing a three-phase service and replacing a three-phase service without interrupting service to the customer. Typical safety practices and job preparations are also covered.

Multimeter Operation


In this course trainees learn the difference between analog and digital multimeters, and how to read and use both types of multimeters. Trainees can then use their knowledge of multimeters in a variety of applications.

Power Quality


Power quality has become an important concern within the utility industry. An understanding of power quality is especially important to workers, such as field operations personnel and special services technicians, who come into contact with the public.


Underground Residential Distribution Systems


This course identifies and describes three common types of underground residential distribution (URD) systems: radial feed, loop feed, and double feed systems. URD components, cables, and terminations are also introduced and discussed. This course also describes how URD cable and equipment are installed. It describes checks performed during typical URD system maintenance inspections and how the flexibility of URD systems allows various portions of a loop feed URD system to be installed without interrupting service to customers.
