The student will learn the importance of engineered documentation from the initial design concept, construction sequencing, and archiving documentation for the future care and maintenance of an existing electrical utility system. This course will cover AC/DC control diagrams, system 1 line, system 3 line, zones of protection, equipment wiring prints, logic diagrams and miscellaneous drawings. Concepts will include a basic understanding of electrical prints/schematics and their importance to the electrical power utility.

Students will study the history and importance of the electric power utility industry. This course includes instruction with regard to electrical utility safety, human performance, and utility regulation. The student will learn the basics of electric utility transformers, breakers, switches, generating plants, substations, power lines and miscellaneous utility infrastructure and operational protocol.

The student will learn the operation details of high voltage transformers.

The student will learn the operation details of high voltage circuit breakers.

This course is designed to provide students with an explanation of the history and philosophy of protective relays. Student will explore the differences between electromechanical and microprocessor based relays, electrical power fuses, fuse curves, and protection coordination in power systems. The different types of protective relays are also discussed and identified. Participants will also learn about current and potential instrument transformers.

Students will be introduced to the principles of operating over-current, line distance, reactance and differential relays. The course will involve discussions on distribution feeder, power transformers, substation bus, and generator protection. Students will participate in the operations of supervisory control and data acquisition (SCADA) equipment and programmable logic controllers (PLC). An introduction to microprocessor relay logic and program calculations is also covered.

This course will introduce students to the grounding and ground field principles associated with substation technologies. Students will be given a basic understanding of the DC current battery systems and battery charges. Substation control house design is explored and an understanding of Mobile Substation and applications is also discussed. Participants will explore the operation of miscellaneous alarm and control circuits.

This capstone project is a requirement for the completion of the A.S. in Engineering Technology Degree with Substation Relay specialization. Participants will be required to demonstrate their ability to engineer control house relay panel drawings in CAD and properly apply those drawings to the construction and wiring of a relay panel. Student must be able to functionally test and commission protective relays in a simulated environment and document print red lining for archival.
