Ekip Touch - Measurements

1 - Standard Measurements

List The Standard measurements are:
Parameter Description
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)
History of minimum and maximum currents, recorded at a settable
Min-Max measurements
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 (In):
Monitor time Normal operating Accuracy of
Measurement
(min-max) range value read (1)
Phase currents (4) 0,004 ÷ 64 In 0,2 ÷ 1,2 In 1% (3)
Internal earth fault current (2) 0,08 ÷ 64 In 0,2 ÷ 1,2 In 2 % (3)
External earth fault current (2) (4) 0,08 ÷ 4 In 0,2 ÷ 1,2 In 2 %
Residual current (2) (5) 2 ÷ 32 A 5 %

(1) the accuracies refer to normal operating ranges, as established by IEC 61557-12
(2) available with LSIG versions
(3) accuracies based on Ekip Touch without Class 1 Power & Energy Metering package; if the Class 1
Power & Energy Metering package is present and for all other trip unit models, check the indicated
performance values from page 41
(4) the higher phase currents are also available in the Histograms, Measuring instruments and
Measurement summary pages
(5) available by activating the presence of toroid S.G.R or Rc
