Facility Project Assignment

Describe a power quality upgrade plan for your facility or for part of your facility. You have two options for this assignment. Pick one and complete it.

Option #1

If your facility is already practicing excellent power quality, detail what was done to achieve this and describe a plan for maintaining a high level of power quality. What ongoing activities are planned to maintain good power quality?

OR

Option #2

Detail how you would set up and implement a power quality survey in your facility. Acting as the facility contact person for the power quality survey, what roles and responsibilities would you have? List the type of information that would need to be gathered to assist the power quality surveyors. How long do you think it would take to complete such a project?
