List
Standard measurements are:
Name
Description
Page
Real-time currents
Real-time measurements of phase currents
Events
List of events, status changes, alarms, recorded by the Trip
unit
Openings
List of trips (TRIP) for current protections
Min-Max
measurements
Log of minimum and maximum currents, recorded with
adjustable interval
Maintenance
CB status: contact wear and last maintenance
Counter operations
Number of mechanical and electrical operations
Real-time
currents
The real-time currents, available on the
Main page
and the
Summary pages
, are the real-time
measurements of phase and ground fault currents expressed in effective value. The
measurement range and the performance depend on the rated current defined by the rated size
of the Trip unit:
