Instantaneous power
Description
Instantaneous power values are real time measurements of the total and phase power
NOTE:
phase power measurements are available with four-pole circuit-breakers or three-pole
circuit-breakers with external neutral.
Representations and access pages
The power measurements are available in different forms, accessible from the following pages:
• In the
Measurements synthesis
page, accessible from the
Histograms
page, there are the measurements
in kW or kVAR of the active, reactive and apparent total power.
• In the
Measuring instruments
page there is a graphical representation in the form of analog meters in
kW or kVAR, for active, reactive and apparent total power.
• In the
Measurements
page there are measurements in kW or to kVAR of the active, reactive and apparent
total power and of phase power (if any).
NOTE: with three-pole circuit-breakers only one Measurements
page is available. With
four-pole circuit-breakers or three-pole + neutral voltage circuit-breakers, there are three
Measurements
pages available that contain all power measurements (one for each phase).
The measurements in kW or kVAR are available with minimum voltages of 5 V and minimum currents of 0.03
In The maximum measurable power value is 1.25 Pn (phase power) / 1,25 Sn ( total power).
NOTE:
with voltages or currents lower than the minimum values, or power higher than 1.25
Pn / 1,25 Sn, the indication “…” is shown.

Path

Description
The presence of the Ekip Measuring Pro module introduces other types of trips, relating to the protections
active with Measuring Pro.
The ways to access theses pages and the information contained are similar to those for the trips of the Basic
protections.
Correlated measurements
The type of protection involved determines the measurements recorded at the moment of tripping:
Protection against
Measurements recorded at the moment of the tripping
Voltage
Phase currents (L1, L2, L3, Of), and line-to-line voltages (U12, U23, U31).
NOTE:
if protection RV trips, U0 is also recorded.
Frequency
Phase currents (L1, L2, L3, Of), and line frequency.
Power
Phase currents (L1, L2, L3, Of), and total power (active or apparent depending
on the protection tripped).
