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.
Measurement Monitor time Accuracy Notes
“_ _ _” (not available) is indicated
Peak factor 0,3 ÷ 6In 1,5% for currents outside the range and
disconnected sensors

Power factor The power factor is the real time measurement of the ratio between total active power and total apparent
power, expressed as cos φ.
Measurement Monitor time Accuracy Notes
“_ _ _” (not available) is indicated for:
Power factor 0,5 ÷ 1 2,5% (1) active and/or reactive power not available
or outside the admissible ranges

(1) accuracy 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

Energy counters The energy counters are the measurements of the total reactive and apparent active energy, updated every
minute.
Measurement Monitor time Accuracy
Total active, reactive and 1 kWh ÷ 2 TWh; 1 kVARh ÷ 2 TVARh; 1 kVAh ÷ 2 TVAh 2 % (1)
apparent energy

(1) accuracy 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
Reset measurements
The Energy RESET command is available in the Energy menu for the purpose of resetting the energy counters
(page 21).
