MEASUREMENT FUNCTION
Measured parameters can be divided to 7 types as follows:
-
Active/ Reactive/ Apparent Power
-
Fundamental/ Harmonic Power
-
RMS for Voltage and Current
-
Power Factor
-
Phase Angle
-
Frequency
-
Temperature
Measured parameters are average values that are averaged among
16 phase-voltage cycles (about 320ms at 50Hz) except for the tempera-
ture. The measured parameter update frequency is approximately 3Hz.
Refer to Table-15.
3.5.1
ACTIVE/ REACTIVE/ APPARENT POWER
Active/ Reactive/ Apparent Power measurement registers can be
divided as below:
-
active, reactive, apparent power
-
all-phase-sum / phase A / phase B / phase C
Altogether there are 12 power registers. Refer to 6.6.1 Power and
Power Factor Registers and the SVmeanT register (98H).
Per-phase apparent power is defined as the product of measured
Vrms and Irms of that phase.
All-phase-sum power is measured by arithmetically summing the
per-phase measured power. The summing of phases can be configured
by the MMode0 register.
3.5.2
FUNDAMENTAL / HARMONIC ACTIVE POWER
Fundamental / harmonic active power measurement registers can be
divided as below:
-
fundamental and harmonic power
-
all-phase-sum / phase A / phase B / phase C
Altogether there are 8 power registers. Refer to 6.6.2 Fundamental/
3.5.3
MEAN POWER FACTOR (PF)
Power Factor is defined for those cases: all-phase-sum / phase A /
phase B / phase C.
Altogether there are 4 power factor registers. Refer to 6.6.1 Power
For all-phase:
For each of the phase::
3.5.4
VOLTAGE / CURRENT RMS
Voltage/current RMS registers can be divided as follows:
Per-phase: Phase A / Phase B / Phase C
Voltage / Current
Altogether there are 6 RMS registers.
Neutral Line Current RMS:
Neutral line current can be calculated by instantaneous value
