Tripping The
Measuring Measurements
page adds to the range of TRIPs that Ekip Touch is able to record (page 114).
The voltage, frequency or power protection that trips determines the measurements recorded the moment
the trip occurs

Notes
Voltage
Currents L1, L2, L3, Ne,
voltages U12, U23, U31, U0 Ne is available with CBs type 4P and 3P + N; U0 is
available in the case of trips due to RV protection
Frequency
Currents L1, L2, L3, Ne and
grid frequency
Ne is available with CBs type 4P and 3P + N
Power
Currents L1, L2, L3, Ne and
total power
Ne is available with CBs type 4P and 3P + N;
Active or apparent total power depending on which
protection tripped
Min-Max-Med measurements
The Measuring Measurements package adds to the range of measurements that Ekip Touch is able to record
(page 110):
• 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 52).
