Tripping The Measuring Measurements page adds to the range of TRIPs that Ekip Touch is able to record (page 115).
The voltage, frequency or power protection that trips determines the measurements recorded the moment
the trip occurs

Min-Max-Med measurements The Measuring Measurements package adds to the range of measurements that Ekip Touch is able to record
(page 111):
• Maximum and medium voltage
• Active, reactive and apparent maximum and medium powers
The type of information given, the available commands and notes are the same as those described for the
current measurements.
NOTES:
• compared to the current measurements, graphic representation is with respect to 1 Un (with
maximum value 1.25 Un) for the voltage recordings and with respect to 1 Sn (with maximum
value 1.25 Sn) for the power recordings
• and the power measurement is negative, the color of the corresponding bar is different from
those with a positive value

Peak factor The peak factors are real time measurements of the ratio between the peak and RMS values of the phase
current; the measurement is supported by the Harmonic distortion protection function (page 61).
