Required measurements for Power Quality Performance monitoring
The following table shows which measurements are required for the different Power Quality Performance components:
NOTE: For each disturbance category, choose only the needed measurements from the supported list to log. Do NOT Log all of them. Logging all measurements can cause unwanted database growth, and performance issues.
