Instantaneous powers

132 | © 2013 ABB | 1SDH001000R0002 - L7804
Description
Instantaneous powers are real time measurements of the total and phase power
NOTE: the measurements of the phase powers are available with four-pole circuit
breakers (4P) or three-pole circuit breakers configured with neutral voltage present
(3P + neutral voltage).
Representations and access pages
The power measurements are available in different representations, 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 powers.
• 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 powers.
• In the Measurements page there are measurements in kW or to kVAR of the active,
reactive and apparent total powers and of phase (if provided).
NOTE: with 3P circuit-breakers only one Measurements page is available. With 4P
circuit-breakers or 3P + neutral voltage circuit-breakers, there are three Measurements
pages available that contain all the measurements of the powers (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.
NOTE:
• With voltages or currents lower than the minimum values, or power higher than
1.25 Pn, the indication "..." is shown.
• Pn is calculated as the product of In and primary Vn

Description
The presence of the Ekip Measuring Pro module provides other types of openings, related to
the protections active with Measuring Pro.
The ways to access theses pages and the information contained are similar to those for
openings of the Basic protections.
Correlated measurements
The protection that trips determines the measurements recorded at the moment of the opening:

Phase currents (L1, L2, L3, Of), and phase-to-phase voltages
(U12, U23, U31).
NOTES: U0 is available with four-pole or three-pole circuit-
breakers configured with voltage on the neutral, in the case of
tripping of protection RV.
Phase currents (L1, L2, L3, Of), and Line frequency.
Phase currents (L1, L2, L3, Of), and total power (active or apparent
depending on the protection tripped).
