Course #: 006038
Duration: 10 hours
Course Prerequisites: Transformers (4040); AC Principles (Block A22); Basic Industrial Math (Block X21);
What Students Learn: The distribution of electrical power is comprised of a total system, starting with the production of electricity and ending with the consumption of electricity. This process includes the planned generation of power based on demand, the long distance transmission system, the local distribution system, and the customer's electrical wiring system. Each of these components includes equipment, material, and many devices that function as individual elements in the successful distribution of usable electrical energy.

In this study unit, students take a tour of the distribution of electrical energy, starting with the various methods of generation, through transmission systems, into the rural and urban substations, and ending at the customer's service entrance.

Duration: 10 hours
Course Prerequisites: AC Principles (Block A22); Basic Industrial Math (Block X21);
What Students Learn: Students learned in a previous study unit that the delivery of power includes several systems of components, including the generating plant, transmission system, subtransmission system, and the distribution system. The most visible method of delivering electricity is overhead transmission and distribution. However, an alternative method of getting electricity from the power plant to the customer is underground, both in the transmission and distribution systems.

This study unit examines methods and equipment associated with the underground primary transmission and distribution, and the secondary distribution, of electricity to the customer.
