3.2.5 Power registers
The meter registers the current power (instantaneous power) in all four qudrants. Registration of active and
reactive Power in the meter use same individually Import/export calculation method as in the case of energy
measurements.
Actual power
Actual power shows the current three-phase power consumption. The actual power can be shown in the display
and is calculated and updated every second.
Peak Power
The peak power is the highest averagely determined power registered during the debiting period. The averagely
determined power is based on a period that corresponds to the integration period. The peak power is available for
P+
max
, P-
max
, Q+
max
and Q-
max
.
Furthermore, the meter can be configured to register the peak power P+
max
for T1 and T2. Thus, the biggest positive
active power during the debiting period is found for T1 and T2, respectively.
At the end of the debiting period, the peak power and the accumulated peak power are stored and a new period
starts. The accumulated peak power accumulates the values of each period and the accumulated peak power of
the previous period. The peak power, however, is reset after each period.
Below the power registers are described:
P+
Active positive instantaneous power of quadrants 1 and 4. The power is displayed in kW in format
4.3 (0000.000).
P- Active negative instantaneous power of quadrants 2 and 3. The power is displayed in kW in format
4.3 (0000.000).
Q+ Reactive positive instantaneous power of quadrants 1 and 2. The power is displayed in kvar in
format 4.3 (0000.000).
Q-
Reactive negative instantaneous power of quadrants 3 and 4. The power is displayed in kvar in
format 4.3 (0000.000).
P+
max
Maximum active positive power during the debiting period measured over an integration period
deriving from quadrants 1 and 4. The power is displayed in kW in format 4.3 (0000.000).
P-
max
Maximum active negative power during the present debiting period measured over an integration
period deriving from quadrants 2 and 3. The power is displayed in kW in format 4.3 (0000.000).
Q+
max
Maximum reactive positive power during the present debiting period measured over an integration
period deriving from quadrants 1 and 2. The power is displayed in kvar in format 4.3 (0000.000).
Q-
max
Maximum reactive negative power during the present debiting period measured over an integration
period deriving from quadrants 3 and 4. The power is displayed in kvar in format 4.3 (0000.000).
P+
max akk
Accumulated maximum active positive power during the present debiting period. To calculate the
accumulated peak power, the peak power of the present debiting period is added to the
accumulated peak power of the last debiting period.
P+
max, daily
Max active power within the 24 hours in question.
P+
min, daily
Min. active power within the 24 hours in question.
Available power registers depend on the chosen energy type. E.g. a two-qudrant meter (A+, A-) only contains P+
and P- power registers.
Power threshold value
It is possible to let a counter register how many times a power threshold value is exceeded. The value only
applies to active positive power P+.
The threshold value can be configured between 0 and 99 kW. If the limit is exceeded within the integration period
(5, 15, 30 or 60 min.), the counting is made in the power threshold counter.
The power threshold counter is registered in the debiting logger of the meter, and is reset at every debiting stop.
