Measurements
instant [2]
NOTES:
(1) Accuracy referring to normal operating ranges according to IEC 61557-12
(2) Available for voltages greater than 30 V (with Un < 277 V) or 60 V (with Un >
277 V)
(3) Accuracy referring to Ekip Touch and Ekip Touch Measuring 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 performance
shown on page 103
(4) 45-55 Hz with setting of frequency = 50 Hz; 54-66 Hz with f = 60 Hz
(5) Pmin = 0.5 In x 5 V; Pmax = 3 x 16 In x 690 V

Openings
The Measuring Measurements package extends the range of TRIPs that Ekip Touch is able to
record (described on page 97 for current protections).
The voltage, frequency or power protection that trips determines the measurements recorded at
the time of opening:

Measurements
Min-Max-Avg
The Measuring Measurements package extends the range of measurements that Ekip Touch is
able to record (described on page 98 for current measurements).
 Maximum and average voltage
 Active, reactive and apparent maximum and average power
The type of information displayed, the commands available and the notes are the same as
described for current measurements.
NOTE: compared to current measurements, the graphical representation is compared
to 1 Un (with a maximum value of 1.25 Un) for voltage records and compared to 1 Sn
(with a maximum value of 1.25 Sn) for power records
