Developing a Location Plan
Depending on the size of the organization, number of departments, and importance of certain locations, note the priority locations. The location plan may change throughout the power quality study as clues may direct you to a possible problem location.
Developing a Tolerance Plan
Thresholds should reflect the equipment being used. Even a heavy piece of machinery such as a CNC machine may be considered sensitive since it has electronic circuits.
The default settings function in EventView software is adequate for most sensitive loads. Some equipment may require tighter tolerances. If so, use the tolerances provided by the manufacturer of the equipment.
Developing the Study Duration Strategy
In order to determine how long to monitor the site, determine the organization’s workload cycle. A workload cycle is the duration of production, whether it is a product or service. A site should be monitored over the entire workload cycle.
Another consideration is the workload cycle vs. the time of day, month or season. At 10:00 AM the organization may be using all of its equipment at once. Air conditioners tend to operate more often in the summer months and space heaters tend to operate in the winter months. This, in conjunction with your organization’s workload cycle, can cause equipment conflicts throughout the year. To determine a workload cycle, answer the questions that are appropriate for your study.
Manufacturing How long does it take to produce a run of your product?
Services How often do you provide your service (daily, seasonally)?
Administration How does your staffing or workload vary (monthly, seasonally)?
Finalizing the Power Quality Monitoring Plan
The key to finalizing the power quality monitoring plan is to publish and assign responsibility for it. The power
