The Event Distribution Graph plots the magnitude of the event against
duration on a logarithmic scale in order to determine the importance of the
data. For example, a single random event may not be as significant as a
cluster of recurring events.
This information can be interpreted using the CBEMA Curve found in
Appendix B,
Power Quality Issues , in the PowerWatch Reference Guide.
Since the impulses have a duration that is unknown, they are represented as
having a width of 10 microseconds.
