Basic Electricity

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.

Underground Residential Distribution Systems

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.

Overhead Troubleshooting 2: Emergency Conditions

COURSE DESCRIPTION

When damage from storms and disasters is extensive, a much larger than normal troubleshooting effort is usually required to get customers back on line as quickly as possible. To support this effort, companies often have special emergency plans in place to make sure that their employees can deal with the problems and conditions that are likely to be encountered. This course examines some of the conditions that tend to make troubleshooting overhead lines under emergency conditions different from normal troubleshooting.

Overhead Troubleshooting 1

COURSE DESCRIPTION

Overhead systems are exposed to many hazards that can lead to a partial or total loss of power. When a problem occurs, troubleshooters are responsible for finding out what is wrong and determining how the problem can be corrected as quickly as possible. In order to locate and identify problems effectively, troubleshooters must be familiar with some basic steps of troubleshooting and know how to apply those steps to various situations. This course identifies some basic steps that can be used to troubleshoot any type of overhead system problem and describes how those steps can be applied in several different troubleshooting situations.

Troubleshooting Overhead Lines

COURSE DESCRIPTION

This course describes methods of safely locating problems on overhead lines that result in loss of power to customers. These methods are called troubleshooting. This begins by describing the logical steps for troubleshooting, one method of troubleshooting called patrolling, common problems to look for, and safety precautions to observe when troubleshooting overhead lines. This program also describes how to locate problems on a primary line using various sectionalizing approaches. It also describes how to locate trouble on secondary lines using various testing approaches.

Transformer Troubleshooting

COURSE DESCRIPTION

This course describes basic procedures for troubleshooting various types of transformers and transformer banks. The course begins by examining different types of transformers, transformer connections, and overcurrent and overvoltage devices that are typically used to protect transformers. The program identifies some typical causes of transformer outages and describes some general considerations involved in responding to a trouble call. The dangers associated with and the potential sources of backfeed are also covered. This course demonstrates procedures for isolating and testing single-phase transformers and three-phase transformer banks. The course also describes how to temporarily restore service in single-phase and three-phase applications.
