Lecture / Lab Hours:
Lab Hours: 30
Prerequisites: RET 120, EET 112 Grading Options:
Introduces the process of power generation. Discussion includes construction techniques involving cranes, rigging, and mechanical alignment procedures. Assemble a functioning scale model of power generating turbine and participate in a safety workshop at a local wind farm. Prerequisites: RET 120, EET 112
Upon finishing this course, students will:
be prepared to work in the power generation field understanding the process of power generation and the assembly, maintenance and operation of the machinery.
be knowledgeable about safety processes and procedures and be prepared to work safely around
cranes and other heavy machinery.
be prepared to work safely alone and within a team on power generation projects.
Outcome Assessment Strategies:
Evaluation is done by midterm and final exams, quality of lab work and of a term project.
