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.

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 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 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 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
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.

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.

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.

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.

COURSE DESCRIPTION
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.
