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.

COURSE DESCRIPTION
The purpose of this unit is to teach the common types of transformers and how they are connected. Basic concepts of transformers and primary systems are covered as well as single-phase connections. Single-phase distribution transformers can be interconnected to provide three-phase power in a number of different ways, providing a utility with the flexibility of meeting a variety of customer needs. This program demonstrates and explains how three-phase delta connections and three-phase wye connections are made. This program also explains how to make delta-wye, wye-delta, and open bank connections.

COURSE DESCRIPTION
Pole top capacitors are connected to circuits to accept and store charges. They are used to help overhead distribution feeder systems operate more efficiently and reliably. This course covers the basic theory and operating characteristics of overhead capacitors, explains how to detect problems in their operations, and demonstrates how to safely replace them when necessary.

COURSE DESCRIPTION
This course explains how to repair and replace energized pole top equipment with a minimum of interruption to customers. It describes how to bypass and replace a recloser. It also shows how to inspect and repair one type of gang-operated switch, and how to bypass and replace a different type.

COURSE DESCRIPTION
Voltage tends to decrease along a distribution feeder. It can also fluctuate above and below acceptable levels due to changing load conditions on the system. This course covers the basic theory and operating characteristics of voltage regulators, explains how to detect problems in their operation, and demonstrates how to safety replace them.

COURSE DESCRIPTION
This course provides an understanding of the basic procedures used to safely remove and install pole top transformers. Although specific types of transformers are used as examples, emphasis is placed on general procedures that apply to the majority of pole top transformers.

COURSE DESCRIPTION
During normal usage, pole top equipment is subjected to conditions such as heat, rain, lightning, and mechanical problems that can lead to equipment damage or failure. This course identifies some equipment used to prevent equipment damage or failure, and to provide coordinated protection for a distribution system. The course also explains how this equipment operates.

COURSE DESCRIPTION
This program reviews the fundamentals of caring for, storing, and inspecting some of the tools and equipment used in transmission and distribution work. The program demonstrates how to perform visual inspections, field inspections, and dielectric tests on rubber protective gear, line hose, hoods, mechanical jumpers, and hot sticks.

COURSE DESCRIPTION
This course introduces students to the principles and techniques of single-point, or equipotential grounding. For best results, students should have a basic knowledge of electrical theory, overhead distribution systems and equipment, grounding theory, equipment, and application and common work methods and procedures used in overhead distribution line maintenance.

COURSE DESCRIPTION
This program reviews some of the factors involved in planning a distribution job, including safety guidelines and site-specific considerations. The program also describes some of the conductors commonly used in secondary construction. In addition, the program reviews the basic procedures for paralleling a service with and without the use of a jumper.
