Single Line Electrical Diagram
The single line electrical diagram is a roadmap of how the electrical system in your facility is connected. The diagram should show the electrical connection from the main service entrance to all of the facility's electrical distribution panels and electrical loads. Accurate record keeping and periodic updates to the diagram ensure that future design changes to the electrical system can be done properly to avoid potential power quality issues.
This diagram along with the electrical disturbance log can help determine the strategic locations in your facility that need to be checked when conducting a site survey or power quality monitoring. As with the electrical disturbance log, accurate information is the key towards resolving the power quality issue.
