This course explains, in general terms, how transmission and distribution systems deliver power from a power plant to customers. The course describes the major components of a typical T&D system, how they function, and how electricity flows through these components on its journey from the power plant to customers.

COURSE DESCRIPTION

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.

COURSE DESCRIPTION

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.

COURSE DESCRIPTION

This course is designed to familiarize trainees with the basic safe work practices and safety equipment that are used in transmission and distribution maintenance work.

COURSE DESCRIPTION

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.

COURSE DESCRIPTION

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.

COURSE DESCRIPTION

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.

COURSE DESCRIPTION

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.

COURSE DESCRIPTION

This program describes some of the common safety hazards found in URD work environments and how to minimize the effects of electrical, atmospheric, and structural hazards. The program also presents a vault emergency situation and discusses safe rescue procedures.

COURSE DESCRIPTION

This program describes two methods of installing underground cable: direct-burying and pulling cable in conduit. The program demonstrates how to lay cable in an open trench and pull cable in conduit. This course also demonstrates how to use various types of equipment and tools for rigging manholes and for pulling cable in conduit.

COURSE DESCRIPTION

This course discusses the basics of underground transformer operations. It presents problems that arise when operating transformers and discusses troubleshooting techniques and inspection procedures. This course also describes the general characteristics of two basic types of pad-mounted switchgear: oil-immersed disconnect switches and transclosures. This course also describes how pad-mounted switchgear can be used to sectionalize and reroute power in an underground feeder system.

COURSE DESCRIPTION

Cable splicing is the process of joining two cable ends together while maintaining the cable’s original design characteristics. This course focuses on cable design, voltage stress and preparation of cables for splicing using a splice kit.

COURSE DESCRIPTION

This course describes splicing three phase primary cables and secondary cables. It also includes splicing in a length of cable and how to install a secondary splice.

COURSE DESCRIPTION

Electrical cables are routinely connected to many different types of equipment. When a connection to equipment is made, the cable must be terminated, or ended, at the connection point. This course discusses pothead, single phase elbow, three-phase elbow and switchgear terminations, how they are installed, and how they help cables function properly. Problems associated with voltage stress are also discussed. This course also explains how to energize three-phase terminations in switchgear and transformers.

COURSE DESCRIPTION

This course is a general introduction to fault location in primary URD cable. The course covers capacitor discharge equipment, how it is used to locate faults, and a demonstration of how to locate a cable fault.

COURSE DESCRIPTION

This course explains how voltage gradient equipment works and demonstrates how to use voltage gradient equipment to locate faults in secondary URD cable.

COURSE DESCRIPTION

This course describes methods that can be used to troubleshoot two types of problems that may affect URD systems: transformer faults and cable faults.
