Maintenance Basics

Rigging 1


Line crews are constantly required to use ropes, blocks, and other special equipment to raise and lower electrical components, tools, and equipment. In order to perform these tasks safely and efficiently, a fundamental knowledge of rigging and rigging equipment is necessary. This program concentrates on the basics of overhead rigging, including safe rigging practices, ropes, knots and knot tying, the use of handlines, and the use of blocks and tackle.

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.

Hydraulic Derricks


Many tools use hydraulic power to make a job easier. Some of the common jobs on electrical systems involve lifting or digging. This program discusses the major working parts, controls, and safe operating procedures for hydraulic derricks. The program also demonstrates how to use a digger derrick to dig a hole and install a utility pole.

Bucket Trucks


This program addresses some of the safety guidelines that should be followed when operating a bucket truck at the job site, including a thorough pre-trip inspection. The program reviews procedures for handling traffic conditions safely and positioning bucket trucks securely on paved, unpaved, and hilly work surfaces. The program also describes safety equipment for using bucket trucks near energized lines, and guidelines for maneuvering bucket trucks around the work area.

Overhead - De-energized

Overhead Distribution Systems


This program covers the basic layout of overhead distribution systems. It explains how to identify circuits and equipment in the field and introduces delta- and wye-connected distribution systems. The basic theory underlying the operation of delta- and wye-connected distribution systems is also presented, and the differences between the two systems are discussed. The program also explains how to differentiate between 34.5 KV systems and 13.2 KV systems.

Pole Framing and Guying


The main function of a utility pole is to support conductors. Because conductors are heavy, they can pull on a pole with a great deal of force. The equipment on a pole that supports the conductors must be constructed to withstand this force. This course describes methods used to frame a pole, that is, how to install crossarms and other conductor supports. This course also describes methods of supporting a pole using several different types of guying techniques.

Setting and Replacing Poles


This program presents some of the equipment and methods that can be used to set utility poles. The program describes three methods for digging holes, and outlines both power-operated and manual methods for installing poles. The program also includes guidelines for installing poles in open areas and safety considerations for installing poles around obstacles and energized lines. Additionally, this course describes basic methods for removing and replacing poles.

Safety in Overhead Line Maintenance


This course examines hazards that may be present during overhead line maintenance operations. The course also introduces protective equipment designed to create a barrier between linemen and high voltage lines and equipment, and reviews safety practices that will help ensure a safe work environment.

Safe Bucket Truck Operation


This course covers several aspects of bucket truck safety, including how to inspect a bucket truck prior to use, how to plan a job with safety in mind, and how to avoid shock hazards associated with working on or near bucket trucks.
