Ekip Touch - Measurements
1 - Standard Measurements
List
The Standard measurements are:
Parameter
Description
Page
Instantaneous currents
Phase current and earth fault measurements in real time
Events
List of events, status changes, alarms, recorded by the Trip unit
Trip
List of current protection trips (TRIP)
Min-Max measurements
History of minimum and maximum currents, recorded at a settable
interval
Maintenance
CB status: contact wear and last maintenance
Operation counters
Number of mechanical and electrical operations
Instantaneous currents
The instantaneous currents, available in the
Measurements
pages, are real time measurements of the phase
and earth fault currents expressed in root mean square value; the monitor time and performance depend on
the rated current defined by the
Rating plug
