Data Sheet

Events
The Events section is a summary of the voltage and current events that occurred at this
location during the monitor period.
Events are defined as changes in the monitored voltage or current. These changes may be
subtle or severe.
Tolerance curves provide a graphical representation of the likelihood of an event to disrupt
equipment operations. Tolerance curves classify the event by magnitude and duration;
there are standardized tolerance curves for voltage such as CBEMA or ITIC and for current,
circuit breaker manufacturers supply curves of their equipments operation.
